更简单的方法

my_num = 6
print(f'{my_num:b}')

python包Binary Fractions包含二进制和二进制分数的完整实现。您可以进行如下操作:

from binary_fractions import Binary
b = Binary(6) # creates a binary fraction string
b.lfill(8) # fills to length 8

这个包有许多其他的方法来完全精确地操作二进制字符串。

def int_to_bin(num, fill):
    bin_result = ''

    def int_to_binary(number):
        nonlocal bin_result
        if number > 1:
            int_to_binary(number // 2)
        bin_result = bin_result + str(number % 2)

    int_to_binary(num)
    return bin_result.zfill(fill)

另一个想法:

>>> bin(6)[2:].zfill(8)
'00000110'

通过字符串插值的更短方法(Python 3.6+):

>>> f'{6:08b}'
'00000110'

    def convertToBinary(self, n):
        result=""
        if n==0:
            return 0

        while n>0:
            r=n%2
            result+=str(r)
            n=int(n/2)
        if n%2==0:
            result+="0"
        return result[::-1]

走老路总是管用的

def intoBinary(number):
binarynumber=""
if (number!=0):
    while (number>=1):
        if (number %2==0):
            binarynumber=binarynumber+"0"
            number=number/2
        else:
            binarynumber=binarynumber+"1"
            number=(number-1)/2

else:
    binarynumber="0"

return "".join(reversed(binarynumber))
