Python —— 随机生成验证码

# 示例一


import random   # 导入一个模块   random:随机
data =  []
for i in range(4):  # 4位验证码
    v = random.randint(78,89)  # 验证码的随机范围是78 ~ 89 .
    data.append(v)
print(data)   #  [81, 84, 82, 87]

------------------------------------

# 示例二


import random
data =  []
for i in range(4):  
    v = random.randint(78,89)
    data.append(chr(v))   #  chr() ：将十进制转换成unicode编码中的对应字符串
    
print(data)       #  ['y','s','o','s']
print(''.join(data))       #  YSOS  

------------------------------------------

# 示例三


import random
def get_random_code(length=6):  #默认验证码长度等于6
    data = []
    for i in range(length):
        v = random.randint(78, 89)
        data.append(chr(v))

    return ''.join(data)

code = get_random_code()
print(code)   # QWVWXO (该验证码随机生成)
