有人可以帮助修复python中函数参数的代码吗

Question

所以我正在尝试制作密码强度检查器，但在尝试检查密码的正确输入长度然后尝试测试运行代码时它显示未定义的名称“pwd”第 12 行。但是我无法找到解决方法这。请帮忙！谢谢。

def pwd_validate(pwd):
# Validate the length of the password
    while True:
        pwd = input("Please enter your new password, it should be 12 characters long: ")
        if len(pwd) == 12:
            print("""Thank you for entering a 12 charcter password 
            Now checking strength of password...""")
            break
        else:
            print("Password must contain only 12 characters please:")

pwd_validate(pwd)

你传递给函数的密码没有定义，它至少应该是一个空字符串。只需在将其传递给函数之前定义它

def pwd_validate(pwd):
# Validate the length of the password
    while True:
        pwd = input("Please enter your new password, it should be 12 characters long: ")
        if len(pwd) == 12:
            print("""Thank you for entering a 12 charcter password 
            Now checking strength of password...""")
            break
        else:
            print("Password must contain only 12 characters please:")

pwd = ""
pwd_validate(pwd)
