How to check if a string is a valid keyword in Python?
Defining a Keyword
In programming, a keyword is a “reserved word” by the language which convey a special meaning to the interpreter. It may be a command or a parameter. Keywords cannot be used as a variable name in the program snippet.
Keywords in Python: Python language also reserves some of keywords that convey special meaning. Knowledge of these is necessary part of learning this language. Below is list of keywords registered by python .
False, elif, lambda,
None, else, nonlocal,
True, except, not,
and, finally, or,
as, for, pass,
assert, from, raise,
break, global, return,
class, if, try,
continue, import, while,
def, in, with,
del, is, yield,
Python in its language defines an inbuilt module “keyword” which handles certain operations related to keywords. A function “iskeyword()” checks if a string is keyword or not. Returns true if a string is keyword, else returns false.

How to print list of all keywords
Sometimes, remembering all the keywords can be a difficult task while assigning variable names. Hence a function “kwlist()” is provided in “keyword” module which prints all the 33 python keywords.
The list of keywords is : ['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']
