1. By Mitali
Made by Mitali. For a given decimal number as input,this code will convert the decimal number into equivalent binary number, E.g If input is “25” the output will be “11001”. Source
The binary equivalent of 1 is 1 .
number=int(input())

rem=number%2
binary+=str(rem)
number=number//2
print("The binary equivalent of "+str(temp)+" is "+binary[::-1]+" .")

About Binary number:
A binary number is a number expressed in the base-2 numeral system or binary numeral system, a method of mathematical expression which uses only two symbols: typically "0" (zero) and "1" (one).
The base-2 numeral system is a positional notation with a radix of 2. Each digit is referred to as a bit, or binary digit. Because of its straightforward implementation in digital electronic circuitry using logic gates, the binary system is used by almost all modern computers and computer-based devices, as a preferred system of use, over various other human techniques of communication, because of the simplicity of the language.
