Python get word in string

How to get the last word from a string in Python?

In this tutorial, I’ll discuss how you can get the last word from a given string in Python. It’s very easy to get the last word from a given string in Python. To get the last word from a string, we have to convert the string into a list at the first. After converting the string into a list, simply we can use the slicing operator to get the last word of the string and then we can print it. For converting a string into a list we can simply use the split() method.

your_string.split(Separator, Maxsplit)

Separator: This is optional. This is used to specify where we want to split the string. By default, it takes whitespace as a separator.

Maxsplit : This is also optional. This is used to specify how many splits we want to do in the given string. By default, it takes the value as -1, which means all the occurrences or no limit on the number of splits.

Now, let me give an example to understand the concept

#taking input from the user string = input("Enter your string: ") #splitting the string words = string.split() #slicing the list (negative index means index from the end) #-1 means the last element of the list print(words[-1])

Enter your string: Welcome to Codespeedy Codespeedy

In this above code, I gave the input as ‘Welcome to Codespeedy’ and it gave me output as ‘Codespeedy’ that is the last word of the string.

So I hope now you’re familiar with the concept of how you can get the last word from a string.

Extract a specific word from a string in Python

While handling text data, sometimes we have to search for occurrences of specific words in the text and extract specific words. In this tutorial, we will learn about different methods to extract a specific word from a string in python using inbuilt string methods and regular expressions.So, let’s dive into it.

Extract a specific word from a string using string slicing in python

If we know the exact position of the word to be extracted from the string, we can perform slicing operation on the string to extract the desired word from the string as shown below.

 search_string= "I am a python programmer and I am writing this code for pythonforbeginners.com" print("String from which word has to be searched is:") print(search_string) print("word to be extracted from string:") word="writing" print(word) #calculate length of the word lword=len(word) #suppose we already know the starting index of word writing i.e. 34 extracted_string= search_string[34:34+lword] print("Extracted word is:") print(extracted_string)

String from which word has to be searched is: I am a python programmer and I am writing this code for pythonforbeginners.com word to be extracted from string: writing Extracted word is: writing

Extract a specific word from a string using find() method.

If we want to extract a specific word from the string and we do not know the exact position of the word, we can first find the position of the word using find() method and then we can extract the word using string slicing.

The find() method when invoked on any string, takes the string to be searched as a parameter and gives as output the position of first occurrence of the input string which was to be searched. If the string to be searched is not present, the find() method returns -1.

After finding the position of the word to be extracted with find() method, we can simply extract it using slice operation as follows.

search_string= "I am a python programmer and I am writing this code for pythonforbeginners.com" print("String from which word has to be searched is:") print(search_string) print("word to be extracted from string:") word="writing" print(word) #calculate length of the word lword=len(word) start_index=search_string.find(word) print("start index of the word in string is:") print(start_index) extracted_string= search_string[start_index:start_index+lword] print("Extracted word is:") print(extracted_string)

String from which word has to be searched is: I am a python programmer and I am writing this code for pythonforbeginners.com word to be extracted from string: writing start index of the word in string is: 34 Extracted word is: writing 

Using index() method.

If we don’t know the exact position of the word to be extracted,we can also use string index() method to find out the exact position of the word and then we can use slicing to extract the word.

The index() method when invoked on any string, takes the string to be searched as a parameter and gives as output the position of first occurrence of the input string which was to be searched. If the string to be searched is not present, index() throws an exception. For this reason we will have to use python try except to handle the exceptions while using index() method.

We can extract a specific word from a string in python using index() method and string slicing as follows.

 search_string= "I am a python programmer and I am writing this code for pythonforbeginners.com" print("String from which word has to be searched is:") print(search_string) print("word to be extracted from string:") word="writing" print(word) #calculate length of the word lword=len(word) try: start_index=search_string.index(word) print("start index of the word in string is:") print(start_index) extracted_string= search_string[start_index:start_index+lword] print("Extracted word is:") print(extracted_string) except: print("word not found") 

String from which word has to be searched is: I am a python programmer and I am writing this code for pythonforbeginners.com word to be extracted from string: writing start index of the word in string is: 34 Extracted word is: writing

Using regular expressions to extract any specific word

We can use regular expressions in python to extract specific words from a string. We can use search() method from re module to find the first occurrence of the word and then we can obtain the word using slicing.

re.search() method will take the word to be extracted in regular expression form and the string as input and and returns a re.MatchObject which contains the starting and ending index of the word.If the given word is not found, re.search() will return None . After getting the indices of the word to be extracted, we can extract it using string slicing as shown below.

import re search_string= "I am a python programmer and I am writing this code for pythonforbeginners.com" print("String from which word has to be searched is:") print(search_string) print("word to be extracted from string:") word=r"writing" print(word) #calculate length of the word lword=len(word) start_index=re.search(word,search_string).start() print("start index of the word in string is:") print(start_index) extracted_string= search_string[start_index:start_index+lword] print("Extracted word is:") print(extracted_string)

 String from which word has to be searched is: I am a python programmer and I am writing this code for pythonforbeginners.com word to be extracted from string: writing start index of the word in string is: 34 Extracted word is: writing

Conclusion

In this article, we have seen how to find any specific word in a string using different string methods and regular expressions and then print the word using string slicing in python. We can also use python string split operation when we just have to search if the word is present or not, given that words are space separated. Stay tuned for more informative articles.

How to get the first word in a string Python

Sometimes we come across situations where we need to get first word in string python. Hence it is often helpful to have shorthands to perform this function. This article also covers the situations where we need all words present in the string.

Method #1: Using split()

Using the split function, we can break the string into a list of words. Use str.split() and list indexing to get the first word in a string. Call str.split() to create a list of all words in str separated by space or newline character. Index the result of str.split() with [0] to return the first word in str.

Get first word in string Python

Getting the first word in a string will return the first series of characters that precede a space or a newline character. For example, getting the first word in the “Tutorials Website” string returns “Tutorials.”

Output:

Get the All words in a string

Getting all words in a string will return the series of characters that precede a space or a newline character. For example,

Output:

[ ‘Tutorials’ , ‘Website’ , ‘is’ , ‘the’ , ‘best’ , ‘Online’ , ‘Web’ , ‘Development’ , ‘Tutorials’ , ‘Portal’ ]

Conclusion:

Using the Split function to Get first word in string python is the most generic and recommended method to perform this particular task. But the drawback is that it fails to contain punctuation marks in string cases.
