Given a string, write a Python program that checks if the given string is keyword or not.
- Keywords are reserved words which cannot be used as variable names.
- There are 33 keywords in Python programming language.(in python 3.6.2 version)
Examples:
Input: str = "geeks" Output: geeks is not a keyword Input: str = "for" Output: for is a keyword
We can always get the list of keywords in the current Python version using kwlist
method in keyword module.
# import keyword library import keyword keyword_list = keyword.kwlist print ( "No. of keywords present in current version :" , len (keyword_list)) print (keyword_list) |
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 Keyword or not:
# include keyword library in this program import keyword # Function to check whether the given # string is a keyword or not def isKeyword(word) : # kwlist attribute of keyword # library return list of keywords # present in current version of # python language. keyword_list = keyword.kwlist # check word in present in # keyword_list or not. if word in keyword_list : return "Yes" else : return "No" # Driver Code if __name__ = = "__main__" : print (isKeyword( "geeks" )) print (isKeyword( "for" )) |
No Yes
