Check if a Number is Binary in Python

❮ Previous Next ❯

A Python program to check whether a given number consists only of 0s and 1s (binary number).

Here’s the explanation in dot points:

Purpose: Checks if a number consists only of 0s and 1s (binary).
Function: is_binary(number) converts the number to a string and checks each digit.
For Loop: Iterates through the string to check if each digit is '0' or '1'.
Return False: Returns False if any digit is not '0' or '1' (not binary).
Return True: Returns True if all digits are either '0' or '1' (binary).
User Input: Takes user input, calls the function, and prints whether the number is binary or not.

Program:

def is_binary(number):
    number_str = str(number)
    for i in number_str:
        if i not in ['0', '1']:
            return False
    return True


number = int(input("Enter a number: "))


if is_binary(number):
    print(f"{number} is a binary number.")
else:
    print(f"{number} is not a binary number.")
