import re

def fun(pwd):
    score = 0
#     规则一、密码长度:
    if len(pwd)<=4:
        score += 5
    elif len(pwd)<=7:
        score += 10
    else:
        score += 25
#     规则二、字母:
    if re.findall('[a-z]', pwd) and re.findall('[A-Z]', pwd):
        score += 20
    elif re.findall('[a-z]', pwd) or re.findall('[A-Z]', pwd):
        score += 10
    else:
        score += 0
#     规则三、数字:
    count = len(''.join(re.findall(r'\d+', pwd)))
    if count==0:
        score += 0
    elif count==1:
        score += 10
    else:
        score += 20
#     规则四、符号:
    count = len(''.join(re.findall('[^0-9a-zA-Z]', pwd)))
    if count==0:
        score += 0
    elif count==1:
        score += 10
    else:
        score += 25
#     规则五、奖励:
    if re.findall('[a-z]', pwd) and re.findall('[A-Z]', pwd) and re.findall(r'\d+', pwd) and re.findall('[^0-9a-zA-Z]', pwd):
        score += 5
    elif re.findall('[a-zA-Z]', pwd) and re.findall(r'\d+', pwd) and re.findall('[^0-9a-zA-Z]', pwd):
        score += 3
    elif re.findall('[a-zA-Z]', pwd) and re.findall(r'\d+', pwd):
        score += 2
#     判断等级
    if score>=90:
        print('VERY_SECURE')
    elif score>=80:
        print('SECURE')
    elif score>=70:
        print('VERY_STRONG')
    elif score>=60:
        print('STRONG')
    elif score>=50:
        print('AVERAGE')
    elif score>=25:
        print('WEAK')
    elif score>=0:
        print('VERY_WEAK')
