想請問要如何讓output的ch能夠在FlipOnePosition()後仍保持一樣的值呢?而s則為flip後的值
output:
Before [1 0 1 1 1]
After [1 0 1 1 1]
s [1 0 1 1 0]

import random
import numpy as np

def FlipOnePosition(pk,num):
    position = random.randint(0, num - 1)
    if pk[position] == 0:
        pk[position] = 1
    else:
        pk[position] = 0
    return pk

if __name__ == "__main__":
    ch = np.random.randint(0, 2, 5)
    print("Before",ch)
    s = FlipOnePosition(ch, 5)
    print("After",ch)
    print("s",s)
    
    '''
    output:
        Before [1 0 1 1 1]
        After [1 0 1 1 0]
        s [1 0 1 1 0]
    '''

import random
import numpy as np

def FlipOnePosition(pk,num):
    ret = pk.copy()
    position = random.randint(0, num - 1)
    if ret[position] == 0:
        ret[position] = 1
    else:
        ret[position] = 0
    return ret

if __name__ == "__main__":
    ch = np.random.randint(0, 2, 5)
    print("Before",ch)
    s = FlipOnePosition(ch, 5)
    print("After",ch)
    print("s",s)
