Convert decimal to binary number in Python program

Python Server Side Programming Programming

In this article, we will learn about the solution to the problem statement given below.

Problem statement − We are given a decimal number, we need to convert it into its binary equivalent.

There are two approaches to solve the given problem. Let’s see them one by one−

Recursive Approach

Example

def DecimalToBinary(num):
   if num > 1:
      DecimalToBinary(num // 2)
   print(num % 2, end = '')
# main
if __name__ == '__main__':
   # decimal input
   dec_val = 56
   # binary equivalent
   DecimalToBinary(dec_val)

Output

All the variables and functions are declared in the global scope shown in the figure above.

Using Built-In method

Example

Live Demo

def decimalToBinary(n):
   return bin(n).replace("0b", "")
# Driver code
if __name__ == '__main__':
   print(decimalToBinary(56))

Output

All the variables and functions are declared in the global scope shown in the figure above.

Conclusion

In this article, we have learned about the python program to convert a list into a string.
