如何将 integer 转换为其二进制表示形式为 numpy 数组？

Question

I'm interested in taking a single integer and converting it to a numpy array of 1's and 0's equal to the number's binary representation. I'd like to fix the length of the array (pad with zeros as needed) while I'm at it. How can this been done?

Something along these lines:

>>> func(19,bits=7)
np.array([0,0,1,0,0,1,1])

Answer 1

Use Python's bin() for binary conversion

def func(x, bits):
    return np.array([int(i) for i in bin(x)[2:].zfill(bits)])
