03. Example: Get All Python Keywords

The following Python program retrieves the complete list of keywords using the keyword module.

Python Code:

import keyword

# Get the list of all Python keywords
keyword_list = keyword.kwlist

# Print the type and the list of keywords
print("Class Type:", type(keyword_list))
print(keyword_list)

# Print the total number of keywords
print("\nTotal Number of Keywords:", len(keyword_list))

Output:

Class Type: <class 'list'>
['False', 'None', 'True', 'and', 'as', 'assert', 'async', 'await', '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']
