Python import for string

Python string Module

In this article, we are going to learn the Python string module. the string is a built-in module in Python which is used to precess the string.
the string is a built-in module, That means the string is pre-installed with Python. In the previous tutorial, we have seen the Python string HTML module.

To understand this example you should have basic knowledge of Python Programming .

    Python String Module:

    Python provides a built-in module named string which provides lots of functions and properties to precess the string.

    Python string module is a built-in Python module that means you don’t need to install it by using pip. To use the string module in Python you need to import using the import keyword.

    Python String Module Properties:

    Let’s look constants, define in the string module.

    string.ascii_letters

    This constants return the combination of ascii.lowercase and ascii.uppercase letters.

    import string x = string.ascii_letters print(x) 

    abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ

    string.ascii_lowercase:

    string.ascii_lowercase constants return the lowercase letters.

    import string x = string.ascii_lowercase print(x)

    abcdefghijklmnopqrstuvwxyz

    string.ascii_uppercase:

    string.ascii_uppercase constants return the upper case letters.

    import string x = string.ascii_uppercase print(x)

    ABCDEFGHIJKLMNOPQRSTUVWXYZ

    string.digits:

    string.digits return the digits.

    import string x = string.digits print(x)

    string.hexdigits:

    The string.hexdigits return the hexadecimal:

    import string x = string.hexdigits print(x)

    string.octdigits:

    The string.octdigits return the hexadecimal.

    import string x = string.hexdigits print(x)

    Output will be:- 01234567

    string.punctuation:

    The string.punctuation return the punctuations.

    import string x = string.punctuation print(x) 

    string.whitespace:

    The string.whitespace return the whitespaces.

    import string x = string.whitespace print(x)

    string.printable:

    The string.printable constants return the combination of ascii_letters, digits, punctuations and whitespace.

    import string x = string.printable print(x)

    0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ!"#$%&'()*+,-./:;?@[\]^_`<|>~ 

    Python string module Helper Functions:

    string module provides function which are used to process the string.

    capwords(s, sep = None)

    The string.capwords() helper function is used to split the string into the words using str.split() function. Then it capitalizes each word using str.capitalize() function. Finally, it joins the capitalized words using str.join().

    Example 1:

    import string txt = "Programming Funda is programming portal" x = string.capwords(txt) print(x)

    Output will be:- Programming Funda Is Programming Portal

    Example 2:

    import string txt = " Programming Funda is programming portal " x = string.capwords(txt, "g") print(x)

    progRamming funda is progRamming portal

    Python string module Classes:

    Python built-in string module provide two class Formatter and Template.

    Formatter:

    Formatter class is used to format the string same as str.format() function.

    from string import Formatter formatter = Formatter() print(formatter.format('', portal = 'ProgrammingFunda is a portal')) print(formatter.format('<> ', 'Programming Funda', portal = 'is a programming portal')) print('<> '.format('Welcome to the', portal = 'programming Funda')) 

    ProgrammingFunda is a portal Programming Funda is a programming portal Welcome to the programming Funda

    Template:

    Template class is used to create the string template for simple string substitute.

    from string import Template temp = Template("$name is the Founder of $portal") s = temp.substitute(name = "Vishvajit Rao", portal = "Programming Funda") print(s)

    Vishvajit Rao is the Founder of Programming Funda

    Conclusion:

    In this tutorial, you have learned about the Python string module. string module in Python provides lots of functions that are used to process the string. This is the legitimate module to work with string.

    I hope this tutorial will help you, if you like this article, please comment and share with your friends who want to learn Python programming from scratch to advanced.

    How to import modules from string in Python?

    

    Dynamic module importing made easy with Python’s importlib

    In Python, you can use the import statement to import a module or package into your code. However, sometimes you may want to dynamically import a module or package from a string, rather than hard coding the module or package name. In this article, we’ll explore how to import modules from string in Python using the importlib module.

    The importlib module provides a number of functions for interacting with the import system, including the import_module function, which can be used to import a module from a string. To use the import_module function, you need to pass it the name of the module as a string, and it will return the module object.

    For example, to import the math module from a string, you can use the following code:

    import importlib module_name = 'math' module = importlib.import_module(module_name) 

    Once you have the module object, you can use it like any other module, accessing its attributes and functions using the dot notation. For example, to use the pi constant from the math module, you can use the following code:

    import importlib module_name = 'math' module = importlib.import_module(module_name) print(module.pi) # 3.141592653589793 

    You can also use the import_module function to import submodules or subpackages from a string. To do this, you simply need to include the submodule or subpackage name in the string, separated by a dot. For example, to import the urllib.parse module from a string, you can use the following code:

    import importlib module_name = 'urllib.parse' module = importlib.import_module(module_name) 

    In addition to the import_module function, the importlib module also provides the import_from_string function, which allows you to import a module or object from a string containing the fully qualified name of the module or object. For example, to import the Decimal class from the decimal module from a string, you can use the following code:

    import importlib module_name = 'decimal.Decimal' module = importlib.import_from_string(module_name) decimal = module('3.14') print(decimal) # 3.14 

    In conclusion, the importlib module provides a number of functions for importing modules and objects from string in Python. By using these functions, you can dynamically import modules or objects
