Convert decimal to binary in python

Question

Hello,

Is there any module or function in python i can use to convert a decimal number to its binary equivalent ? I am able to convert binary to decimal using int('[binary_value]',2),so any way to do the reverse without writing the code to do it myself ?

Thank You

Answer 1

all numbers are stored in binary. if you want a textual representation of a given number in binary, use bin(i)

>>> bin(10)
'0b1010'
>>> 0b1010
10

Answer 2

"{0:#b}".format(my_int)

I agree with @aaronasterling's answer. However, if you want a non-binary string that you can cast into an int, then you can use the canonical algorithm:

def decToBin(n):
    if n==0: return ''
    else:
        return decToBin(n/2) + str(n%2)
