How To Extract A Word From A List In Python

👻 Bank check our latest review to cull the all-time laptop for Machine Learning engineers and Deep learning tasks!

Method # i: Using carve up()
Using the split function, we can split up a string into a list of words, and this is the most mutual and recommended method if someone wants to consummate this specific task. But the downside is that it doesn't work in cases where the string contains punctuation marks.

# Python3 lawmaking to demonstrate # to extract words from string # using split()  # initializing cord test_string = "Python.Technology is all-time Reckoner Science Portal"  # press original string impress ("The original string is : " + test_string)  # using split up() # to excerpt words from string res = test_string.split()  # press result impress ("The list of words is : " + str(res))        

Output:

The original string is: Python.Engineering is best Informatics Portal
The list of words is: ['Python.Engineering science',' is', 'best', 'Computer', 'Scientific discipline', 'Portal']

How to extract a word from a string in Python

Method # 2: Using regex (findall ())
In cases that contain all special characters and punctuation marks, equally discussed higher up, tr The traditional method of searching for words in a cord using splitting tin fail and therefore requires regular expressions to accomplish this task. The findall office returns a list after filtering the string and extracting words, ignoring punctuation marks.

# Python3 lawmaking to demonstrate # to excerpt words from string # using regex( findall() ) import re  # initializing string test_string = "Python.Engineering science, is best @# Computer Science Portal.!!!"  # printing original string impress ("The original string is : " + test_string)  # using regex( findall() ) # to extract words from string res = re.findall(r'west+', test_string)  # press result print ("The list of words is : " + str(res))        

Output:

The original string is: Python.Engineering science, is best @ # Information science Portal. !!!
The listing of words is: ['Python.Engineering', 'is', 'best', 'Co mputer ',' Science ',' Portal ']

Method # three: Using regex () + string.punctuation
This method likewise used regular expressions, only the get all punctuation string function is used to ignore all punctuation and get the filtered consequence cord.

# Python3 code to demonstrate # to extract words from string # using regex() + string.punctuation import re import string  # initializing cord test_string = "Python.Engineering, is best @# Computer Science Portal.!!!"  # press original cord print ("The original string is : " + test_string)  # using regex() + string.punctuation # to excerpt words from string res = re.sub('['+string.punctuation+']', '', test_string).split()  # press result print ("The list of words is : " + str(res))        

Output:

The list of words is: ['Python.Engineering', 'is', 'best', 'Computer', 'Science', 'Portal']

Getting the get-go word from a cord

I study Python, at that place is a problem - to receive the beginning word from a line. The string may start with spaces, dots, etc. ("….case, strings"). We demand a office that will render the discussion "instance". My code in which I managed to go the word, simply I can't get rid of the comma:

will impress "Hullo", only if the string is "Hello, world" then it volition print "globe"

In this approach, all words volition be found:

>>> import re >>> word = '.... example, cord' >>> pattern = re.compile(r'westward+') >>> pattern.findall(word)[0] 'case'        

In this, only the first match:

>>> blueprint.search(word).grouping() 'example'        

Example without regular expressions:

>>> for i in word: ...     if not i.isalpha() and i != ' ': ...             word = word.replace(i, '') ... >>> word ' example string' >>> word.split()[0].strip() 'example'

I was preparing for my coding interview, cheers for clarifying this - Python Extract words from a given string in Python is not the simplest one. I but hope that will not emerge anymore

Thanks for explaining! I was stuck with Python Excerpt words from a given string for some hours, finally got information technology done 🤗. I am just not quite sure it is the best method

re Python module is always a fleck confusing 😭 Python Extract words from a given string is not the only problem I encountered. Volition get back tomorrow with feedback
