【程序改错】下列给定程序中，fun函数的功能是： 分别统计字符串中大写字母和小写字母的个数。请改正程序中的错误，使它能得出正确的结果。例如：给 字符串s输入：AAaaB Bb6123CCcccd，则应输出： wpper=6， lower=8。 注意：不可以增加或删除程序行，也不可以更改程序的结构。一 --'"' def Upper(s): a = 0 for i in range(len (s)): if ( stil >= 'A' and sil 'a' and $1<'2):1216+=1retarn b def main0:s= input("请输入一个字符串，并按回车继续：”) upper = Upper(s) lower = Lower(s) print("upper = §}, lower = O". format (upper, lower)) if . name == ' main ': main()

There are multiple syntax errors in the provided code. Here's the corrected code:

def Upper(s):
    a = 0
    for i in range(len(s)):
        if s[i] >= 'A' and s[i] <= 'Z':
            a += 1
    return a

def Lower(s):
    b = 0
    for i in range(len(s)):
        if s[i] >= 'a' and s[i] <= 'z':
            b += 1
    return b

def main():
    s = input("请输入一个字符串，并按回车继续：")
    upper = Upper(s)
    lower = Lower(s)
    print("upper = {}, lower = {}".format(upper, lower))

if __name__ == '__main__':
    main()

The changes made to the code are:

1. Added missing colons at the end of function definitions.
2. Corrected the if conditions in Upper and Lower functions.
3. Fixed the typo in the if condition of Upper function.
4. Replaced the special character '§' in the print statement with a curly brace '{'.
