Python Program to Convert Decimal to Binary

Jul 20, 2017

Using Loop


To convert Decimal to binary we check if the number is divisible by 2, if yes then we take a string and append 0 to and and if not then append 1 to it and divide the number by 2 and do the same again.

finally we reverse the string and print the result

numb = 121
binary = '' 

while(numb):
 if(numb % 2 == 0):
  binary += '0'
 else:
  binary += '1'
 numb = numb//2

''.join(reversed(binary))

print(binary)

Using Inbuilt function

 converting decimal to binary is quite easy

a = bit(121)
print(a[2:])
