Question
What will be the output of the following Python code snippet?print('my_string'.isidentifier())OptionsTrueErrorNoneFalse
Solution
The output of the given Python code snippet will be True.
Here's the step by step explanation:
-
The
isidentifier()function in Python is used to check if a string is a valid identifier or not. An identifier is a name given to entities like class, functions, variables, etc. It helps to differentiate one entity from another. -
In the given code, 'my_string' is a valid identifier as it follows the rules of being an identifier - it starts with a letter (a to z or A to Z) or an underscore (_), followed by zero or more letters, underscores and digits (0 to 9).
-
Therefore, when we call 'my_string'.isidentifier(), it returns True because 'my_string' is a valid identifier.
