Question

Which of the following cannot be a variable in python?

(а) IN

(b) Name.student

(c) FOR

(d) False​

Answer 1

(b) Name.student and (d) False cannot be variables in Python.

Variables, or to be more specific, identifiers, are names given to identify a value/function/for storing values, etc.

• An identifier should have no special characters [except an underscore(_)] in them.

Name.student has a special character [a fullstop] in it, and hence cannot be called an identifier.

• An identifier shouldn't be a keyword either.

Keywords in Python are reserved words used for a specific function/purpose.

False is a Boolean value, and cannot be used as an identifier.
