In this article, we will learn about the solution and approach to solve the given problem statement.

Problem statement

Given a number we need to convert into a binary number.

Approach 1 − Recursive Solution

DecToBin(num):
   if num > 1:
      DecToBin(num // 2)
      print num % 2

Example

def DecimalToBinary(num):
   if num > 1:
      DecimalToBinary(num // 2)
   print(num % 2, end = '')
# main
if __name__ == '__main__':
   dec_val = 35
   DecimalToBinary(dec_val)

Output

100011

All the variables and functions are declared in the global scope as shown below −

Approach 2 − Built-in Solution

Example

 Live Demo

def decimalToBinary(n):
   return bin(n).replace("0b", "")
# Driver code
if __name__ == '__main__':
   print(decimalToBinary(35))

Output

100011

All the variables and functions are declared in the global scope as shown below −

Conclusion

In this article, we learnt about the approach to convert a decimal number to a binary number.
