如果你正在寻找与hex()等价的bin()，它是在python 2.6中添加的。

例子:

>>> bin(10)
'0b1010'

使用numpy pack/unpackbits，它们是你最好的朋友。

Examples
--------
>>> a = np.array([[2], [7], [23]], dtype=np.uint8)
>>> a
array([[ 2],
       [ 7],
       [23]], dtype=uint8)
>>> b = np.unpackbits(a, axis=1)
>>> b
array([[0, 0, 0, 0, 0, 0, 1, 0],
       [0, 0, 0, 0, 0, 1, 1, 1],
       [0, 0, 0, 1, 0, 1, 1, 1]], dtype=uint8)

下面是我刚刚实现的代码。这不是一个方法，但你可以把它作为一个现成的函数使用!

def inttobinary(number):
  if number == 0:
    return str(0)
  result =""
  while (number != 0):
      remainder = number%2
      number = number/2
      result += str(remainder)
  return result[::-1] # to invert the string

计算二进制数:

print("Binary is {0:>08b}".format(16))

计算一个数的十六进制小数:

print("Hexa Decimal is {0:>0x}".format(15))

计算所有的二进制直到16::

for i in range(17):
   print("{0:>2}: binary is {0:>08b}".format(i))

要计算十六进制小数，直到17

 for i in range(17):
    print("{0:>2}: Hexa Decimal is {0:>0x}".format(i))
##as 2 digit is enogh for hexa decimal representation of a number

def binary(decimal) :
    otherBase = ""
    while decimal != 0 :
        otherBase  =  str(decimal % 2) + otherBase
        decimal    //=  2
    return otherBase

print binary(10)

输出:

1010

你可以这样做:

bin(10)[2:]

or :

f = str(bin(10))
c = []
c.append("".join(map(int, f[2:])))
print c
