有人可以帮助我理解此代码吗？ 我的朋友将其发送给我，但是不想帮助我理解它，这是我的家庭作业。 如果您为每行代码写下一个主题标签以帮助我理解它，将不胜感激。

passlen是一个字符串，您正尝试将其转换为整数，您不应这样做，而应使用len来获取输入字符串的长度
根据密码中的字符数，更正下面的代码，它从字符列表中随机选择许多字符，并打印出字符串
from random import *
#List of characters to choose from
s="""1234567890+!#$%&/()=?qwertyuiopasdfghjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM
,.-;:_*@<>≤≥©™£€∞§|[]≈±`•Ω醵üıπß∂ƒ¸˛√ª÷≈ç‹›‘’°˝É‡˜ÜŒ∏◊∑∆∫¯˘¬º⁄Ç«»“”"""
while True:
while True:
#Take the password string as input, and use len to get the length of password
passlen = len(input("""Password must between 8 and 16 character """))
#Once the password of correct length is printed, exit the loop
if 8 <= passlen <= 16:
break
#For the length of password, pick a random character from string s and print it
for i in range(passlen):
print(s[randint(0, len(s))], end="")
print()
