如何优化这个随机通道生成器？

Question

初学者在这里，我尝试制作一个随机密码生成器，但我觉得有一种更有效的方法，请帮助，谢谢！

import random
x = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 
'q', 'r', 's','t', 'u', 'v', 'w', 'x', 'y', 'z']
y = ['a', 'b', 'c', 'd', 'e', 'f', 'g', 'h', 'i', 'j', 'k', 'l', 'm', 'n', 'o', 'p', 
'q', 'r', 's','t', 'u', 'v', 'w', 'x', 'y', 'z']
z = ['1', '2', '3', '4', '5', '6', '7', '8', '9', '0']
for i in range(len(y)):
    y[i] = y[i].upper()
g = 1
while g == 1:
    a = random.choice(x)
    b = random.choice(y)
    c = random.choice(z)
    d = random.choice(x)
    e = random.choice(y)
    f = random.choice(z)
    h = random.choice(x)
    i = random.choice(y)
    j = random.choice(z)
    k = random.choice(x)
    l = random.choice(y)
    m = random.choice(z)
    n = random.choice(x)
    o = random.choice(y)
    p = random.choice(z)
    break
print(a+b+c+d+e+f+h+i+j+k+l+m+n+o+p)

Answer 1

首先，简化您的字符串创建：

import string

# this will give you all upper and lower case letters and numbers 0-10
all_chars = string.ascii_letters + string.digits

然后，只需用户random.choice在all_chars范围内：

# the length of your string will be range(x) - 1
print(''.join(random.choice(all_chars) for i in range(10)))

输出：

bHGsT5swSv

所以完整的代码：

import string
import random

all_chars = string.ascii_letters + string.digits
# 'abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789'

# 9 character output
print(''.join(random.choice(all_chars) for i in range(10)))

# or as suggested by the comments using unpacking
print(*random.choices(all_chars, k=10), sep='')
