Question

Which of the following is an invalid statement?

(a) abc = 1,000,000

(b) a b c = 1000 2000 3000

(c) a,b,c = 1000, 2000, 3000

(d) a_b_c = 1,000,000

I got this question in class test.

The origin of the question is Variable Names in chapter Variable Names, Operators, Data Types & Numeric Types of Python

Answer 1

The correct answer is (b) a b c = 1000 2000 3000

To explain I would say: Spaces are not allowed in variable names.
