Python program to check if a given string is a keyword or not

|

Given a line, write a Python program that checks if a given line is a keyword or not.

  • Keywords — these are reserved words that cannot be used as variable names.
  • There are 33 keywords in the Python programming language (in Python 3.6.2)

Examples:

  Input:  str = "geeks"  Output:  geeks is not a keyword  Input:  str = "for"  Output:  for is a keyword 

We can always get a list of keywords in the current version of Python using the kwlist method in the keywords module.

# import keyword library

import keyword

 

keyword_list = keyword.kwlist

print  ( "No. of keywords present in current version: " ,

  len (keyword_list))

  

print (keyword_list)

Exit :

No. of keywords present in current version: 33
[’False’, ’None’, ’True ’,’ and ’,’ as’, ’assert’, ’break’, ’class’,’ continue ’,’ def ’,’ del ’,’ elif ’,’ else ’,’ except ’,’ finally ’, ’for’, ’from’, ’global’, ’if’, ’import’, ’in’, ’is’,’ lambda ’,’ nonlocal ’,’ not ’,’ or ’,’ pass’, ’raise ’,’ return ’,’ try ’,’ while ’,’ with ’,’ yield ’]

Below is the Python code to check if a given string is a keyword:

# enable library key output words to this program

import keyword

 
# Function to check if a given one
# string is a keyword or not

def isKeyword (word):

 

# kwlist keyword attribute

# the library returns a list of keywords

# present in current version

# python language.

keyword_list = keyword.kwlist

 

# check the word currently in

# keyword or not.

if word in keyword_list:

return "Yes"

  else :

return "No"

 

 
Driver code

if __ name__ = = "__ main __" :

 

print (isKeyword ( " geeks " ))

print (isKeyword ( "for" ))

Exit :

 No Yes
