Binary to decimal converter

Implement a module with a main that reads a string representing a binary number from the keyboard. If any character in the string is different from 0 or 1, the program will warn the user that the entered string does not represent a binary number and will ask to read the string again. Finally, the main will display the decimal integer value of the entered binary number.

In the main you must use 2 functions that you have to define, and test with pytest:

• check_if_is_binariy that given a text string, it returns True if the string is composed of only 0 and 1, and if it does not, it returns False.

• convert to convert a string in binary format (i.e. only 0 and 1) to decimal format.

What test cases would you run to test your main well? And for the 2 functions? Implement the tests with pytest.
