编写一个返回数组中任意数量的十六进制颜色的函数

import random

def generate_hex_colors(num):
    colors = []
    for _ in range(num):
        color = '#{:06x}'.format(random.randint(0, 0xFFFFFF))
        colors.append(color)
    return colors

colors = generate_hex_colors(5)
print(colors)

['#a1b2c3', '#4d5e6f', '#7f8a9b', '#e0f1d2', '#3c4e5a']
