Printing Dictionary in Python

A dictionary is a data structure that stores key-value pairs. When you print a dictionary, it outputs pairs of keys and values.

Let’s take a look at the best ways you can print a dictionary in Python.

Print dictionary

The content of a Python dictionary can be printed using the print() function.

If you run the code, Python is going to return the following result:

Both keys and values are printed.

You can also use the dictionary method called items().

This function will display key-value pairs of the dictionary as tuples in a list.

dict_items([('brand', 'Toyota'), ('model', 'Corolla'), ('year', 2018)])

Printing with the for loop

items() can be used to separate dictionary keys from values. Let’s use the for loop to print the dictionary line by line.

If you run the code, the key-value pair will be printed using the print() function.

brand Toyota model Corolla year 2018

Print keys and values separately

With the items() method, you can print the keys and values separately.

for values:

Python offers additional methods keys() and values() methods to achieve the same result.

keys() method:

values() method:

Using list comprehension to print dictionary

With a list comprehension, we can print a dictionary using the for loop inside a single line of code.

This code will return the contents of a dictionary line by line.

brand Toyota model Corolla year 2018

In a similar manner, you can also do list comprehension with keys() and values().

brand model year Toyota Corolla 2018

Prettyprint dictionaries as a table

If a dictionary becomes more complex, printing it in a more readable way can be useful. This code will display the dictionary as a table.

Inside the new dictionary, four elements represent multiple cars. The first part is a key, and the second part (value) is a list consisting of the brand of a car, its model, and its year of production.

The first print() function displays four headers: “Key”, “Brand”, “Model”, “Year”. Each of them is spaced by the number of characters from the previous column.

The same is done to the dictionary items. Each value is a list assigned to three variables: brand, model, and year, with the same amount of spacing.

If you run the code, you’ll see a dictionary displayed in a pretty tabular form.

Key Brand Model Year 11 Toyota Corolla 2018 2 Audi A6 2014 4 Citroen C5 2009 7 Ford Focus 2017

Как распечатать элементы словаря в Python

Чтобы напечатать элементы словаря пары ключ:значение, вы можете использовать dict.items(), dict.keys() или dict.values.(), функцию print().

В этом руководстве мы рассмотрим примеры программ, чтобы напечатать словарь как одну строку, словарь пары ключ:значений по отдельности, ключи словаря и значения словаря.

Распечатать словарь, как одну строку

Чтобы распечатать все содержимое словаря, вызовите функцию print() со словарем, переданным в качестве аргумента. print() преобразует словарь в одностроковый литерал и выводит на стандартный вывод консоли.

В следующей программе мы инициализируем словарь и распечатаем его целиком.

dictionary = print(dictionary)

Как распечатать пары ключ:значение?

Чтобы распечатать пары ключ:значение в словаре, используйте цикл for и оператор печати для их печати. dict.items() возвращает итератор для пар ключ:значение во время каждой итерации.

В следующей программе мы инициализируем словарь и распечатаем пары ключ:значение словаря с помощью цикла For Loop.

dictionary = for key,value in dictionary.items(): print(key, ':', value)

Печать ключей словаря

Чтобы напечатать ключи словаря, используйте цикл for для обхода ключей с помощью итератора dict.keys() и вызова функции print().

В следующей программе мы инициализируем словарь и распечатаем ключи словаря с помощью For Loop.

dictionary = for key in dictionary.keys(): print(key)

Печать значения словаря

Чтобы распечатать значения словаря, используйте цикл for для просмотра значений словаря с помощью итератора dict.values() и вызова функции print().

В следующей программе мы инициализируем словарь и распечатаем значения словаря с помощью For Loop.

dictionary = for value in dictionary.values(): print(value)

Printing dictionary python – Python: Print items of a dictionary line by line (4 ways)

How to print items of a dictionary line by line in python ?

Printing dictionary python: In python a dictionary is one of the important datatype which is used to store data values in key : value pair. Generally keys and values are mapped one-to-one. But it is not impossible that we can not map multiple values to a single key. So in this article we will discuss how we can map multiple values per key in dictionary. Let’s see left what else, python print dictionary keys and values, Python print dictionary pretty, Python print dictionary as table, Python print dictionary value, Print list of dictionaries python, Print nested dictionary python, Python print items of a dictionary line by line 4 ways *0#, Print dictionary items line by line python, Print dictionary line by line python, Print dictionary python in one line, Print list items line by line python, Print list in line python.

Syntax of dictionary :

• key1, key2… represents keys in a dictionary. These keys can be a string, integer, tuple, etc. But keys needs to be unique.
• value1, value2… represents values in dictionary. These values can be strings, numbers, list or list within a list etc.
• key and value is separated by : (colon) symbol.
• key-value pair symbol is separated by , (comma) symbol.

Example of a dictionary population where multiple values are associated with single key.

So, let’s first create a dictionary and we will see how it prints the dictionary in a single line.

#Program #dictionary created population = #printing dictionary in a line print("Printing dictionary in a single line :") print(population)

Output : Printing dictionary in a single line : population =

It was very easy to print dictionary in a single line as to print the dictionary we just passed the dictionary name i.e population in the print statement. As the dictionary is small so we printed it in a single line also we understood it easily.

But think about a situation when the dictionary is too big and we need to print the dictionary line by line means one key-value pair in a single line then next key-value pair in next line and so on. It will be very easy for us also to understand a big dictionary very easily. So, in this article we will discuss how we can print items of a dictionary in line by line.

Method -1 : Print a dictionary line by line using for loop & dict.items()

Python print a dictionary: In python there is a function items( ) , we can use that along with for loop to print the items of dictionary line by line. Actually dict.items( ) returns an iterable view object of the dictionary which is used to iterate over key-value pairs in the dictionary.

So, let’s take an example to understand it more clearly.

#Program #dictionary created population = #printing dictionary in line by line # Iterating over key-value pairs in dictionary and printing them for key, value in population.items(): print(key, ' : ', value)

Output : Odisha: 40000000 Telangana: 50000000 Delhi: 80000000 Goa: 10000000

Method -2 : Print a dictionary line by line by iterating over keys

Python print dict: Like in method-1 we did iterate over key-value pair, in method-2 we can only iterate over key and for each key we can access its value and print the respective value.

So, let’s take an example to understand it more clearly.

#Program #dictionary created population = #printing dictionary in line by line # Iterating over key in dictionary and printing the value of that key for key in population: print(key, ' : ', populationPython print словаря построчно)

Output : Odisha: 40000000 Telangana: 50000000 Delhi: 80000000 Goa: 10000000

Method -3 : Print a dictionary line by line using List Comprehension

Print python dictionary: Using list comprehension and dict.items() , the contents of a dictionary can be printed line by line.

So, let’s take an example to understand it more clearly.

#Program #dictionary created population = #printing dictionary in line by line [print(key,':',value) for key, value in population.items()]

Output : Odisha: 40000000 Telangana: 50000000 Delhi: 80000000 Goa: 10000000

Method -4 : Print a dictionary line by line using json.dumps()

Python print dictionary: In python, json.dumps( ) is provided by json module to serialize the passed object to a json like string. So to print the dictionary line by line we can pass that dictionary in json.dumps( ).

So, let’s take an example to understand it more clearly.

#Program import json #dictionary created population = #printing in json format print(json.dumps(population, indent=1))

Output : Odisha: 40000000 Telangana: 50000000 Delhi: 80000000 Goa: 10000000

Print Dictionary Line by Line in Python

Python provides four data types for collecting and storing data. These data types are also known as Python Collections. One of these four data types is a dictionary.

A dictionary is capable of storing the data in key:value pairs, due to which there are certain styles in which it can be printed. This tutorial focuses on and demonstrates the different ways available to print a dictionary line by line in Python.

One of the four collection data types, a dictionary is a changeable and ordered collection that is able to store and retain data in key:value pairs. Much like a set, a dictionary does not allow any duplicity.

Important: Dictionaries used to be unordered before Python 3.7. In all the newer versions of Python after the 3.7 release, all dictionaries are ordered.

How To Print Dictionary Line by Line in Python?

There are four ways that can assist with the task of printing a dictionary line by line in Python, with all four of them being a little different from each other. All the ways are thoroughly described in the article below.

Using the dict.items() function along with the for loop

The dict.items() function is utilized to get a more readable and iterable view of the dictionary objects by which we can iterate over all the key:value pairs in the dictionary. This function alone though, would not get us the optimum result.

The dict.items() function, when utilized with the for loop is able to properly access both the key and the value pairs and is able to print them line by line.

The following code uses the dict.items() function along with the for loop to print a dictionary line by line in Python.

The above code provides the following output:

The advantage of making use of this method is that the control over each key:value pair is totally in the user’s hands.

Using the dict.items() functions along with List Comprehension

List Comprehension aids in making the core more compact and is an easier way to create lists with reference to an already existing list.

However, apart from creating lists, when List comprehension is utilized with the dict.items() function, it can implement the task of printing a dictionary line by line in Python.

The following code uses the dict.items() functions along with List Comprehension to print a dictionary line by line in Python.

The above code provides the following output:

Iterating over keys to print a dictionary line by line in Python.

This is a more unconventional method as compared to the one mentioned above, as it involves two separate operations which need to be understood and implemented.

In this way, we iterate over each key one by one, and post accessing the certain key , we access the value assigned with it and print both of them in a separate line.

The following code iterates over keys to print a dictionary line by line in Python.

The above code provides the following output:

Using the json.dumps() function

JSON is a big part of the Python programming world and stands for JavaScript Object Notation . It has a crucial role in major areas of Python programming and is basically a syntax that is utilized for the purpose of storing and exchanging data.

One such function provided by the JSON module is the json.dumps() function that is able to serialize the given object into a string that is similar to a JSON string.

In other words, this function passes the dictionary and a string is generated that contains all the key:value pairs in the given dictionary in separate lines. This string can then easily be printed with the generic print function.

The JSON module needs to be imported to the Python code first in order to implement this method.

The following code uses the json.dumps() function to print a dictionary line by line in Python.
