Program to convert decimal to binary in python

The python program to convert decimal to binary using recursion is as follows:

 

# Owner : TutorialsInhand Author : Devjeet Roy

def decimal_to_binary(n):
    if n > 1:
        decimal_to_binary(n//2)
    print(n%2, end = "")

if __name__ == "__main__":
    number = int(input("Enter a number: "))
    decimal_to_binary(number)

The output of python program to convert decimal to binary using recursion is as follows:

 

PS C:\Users\DEVJEET\Desktop\tutorialsInHand> python code.py
Enter a number: 7
111

Few important tips about this program

1. Here, we ask the user to enter a number and we type convert it to integer data type.

2. Then we call the function "decimal_to_binary" to convert the number to binary.

3. The function calls itself until the number itself becomes less than 1. We have used recursion here.

4. Python provides a bin() function whicn can directly convert a decimal number to binary.
