Question

Mark and John are developing a program using Python. They name a variable 24_hour_mart, but then recognize that this name violates a Python naming convention. What naming convention does it violate?
Variable names can not include the underscore character (_).
Variable names can not begin with a number.
Variable names can not exceed ten characters in length.
Variable names can not be fewer than fifteen characters in length.

Answer 1

Answer:

Option 2: Variable names can not begin with a number.

Explanation:

As given Mark and John named a variable as 24_hour_mart while writing a program in python.

While it is forbidden to name a variable starting with any digit, only alphabets (capital and smaller) and underscore can be the first letter of the variable name.

Moreover, by considering the other options given:

• Variable name can include the underscore (_) between the words. It is used instead of spaces that are not allowed.
• There is no upper limit for variable length, it can be of any reasonable length and more than 10 characters say 11 or 12 are reasonable.

• There is no lower limit for variable length, it can be any reasonable length , even it can be of 1 character.

Variables named in python language must not be the keywords as they are reserved for other purposes.
