在python中将十进制分数转换为二进制

Question

I am trying to convert decimal fractions to binary in python. Can anyone help

def deci_to_bin(n):
    c=n%2
    print c
    n=n/2
    if n == 1:
        print n
        print n "conversaion of decimal to binary is given above see button to top"

    else:
        return deci_to_bin(n)

n=int(raw_input("enter decimal digit"))
deci_to_bin(n)

So far I got this but I keep on getting an error

Answer 1

您需要单独print参数 -> print n, "your text"

Answer 2

You can always use the Binary fractions package.

Example:

>>> from binary_fractions import Binary
>>> b = Binary(15.5)
>>> print(b)
0b1111.1
>>>

It has many more helper functions to manipulate binary strings such as: shift, add, fill, to_exponential, invert...

PS: Shameless plug, I'm the author of this package.
