随机生成指定位数的验证码

import random
import string

# 方法一：
def code_1(m, choice):
    code=‘‘.join(random.sample(choice, m))
    return code

print(code_1(4, string.ascii_letters + string.digits))

# 方法二：
def code_2(n):
    code=‘‘
    for i in range(n):
        number=random.randint(0, 9)  # 0-9
        lower_char=chr(random.randint(97, 122)) # a-z
        upper_char=chr(random.randint(65, 90)) # A-Z
        char_1=random.choice([number, lower_char, upper_char])
        code+=str(char_1)
    return code

print(code_2(4)

print(random.randint(1,100))

print(random.randrange (0,100,2))

print(random.randrange ( 1 , 100 , 2))

print(random.random())
print(random.uniform(1,10))

print(random.choice(r‘qwertyuiop[]\asdfghjkl;zxcvbnm,./‘))

print(code=‘‘.join(random.sample(choice, m)))
