Python:输入一个密码，判断其强度（源码+效果图）

源码：

t = input("请输入字符串：")
upper, lower, digit, space, other = 0, 0, 0, 0, 0
for i in t:
    if i.isalnum():
        lower = 1
    elif i.islower():
        lower = 1
    elif i.upper():
        upper=1
    elif i.isspace():
        space = 1
    else:
        other=1
x = lower+upper+digit+space+other
if(x==5):
    print("强")
elif(x==4):
    print("较强")
elif(x==3):
    print("较弱")
elif(x==2):
    print("弱")
elif(x==1):
    print("极弱")
else:
    print("不合格")
