Python编写读取和查找2个文件中匹配字母的数量并返回此数字的程序

import re

def count_matching_letters(file_path):
    with open(file_path, 'r') as file:
        content = file.read()
        matching_letters = re.findall('[a-zA-Z]', content)
        return len(matching_letters)

file1_path = 'path/to/file1.txt'
file2_path = 'path/to/file2.txt'

file1_matching_letters = count_matching_letters(file1_path)
file2_matching_letters = count_matching_letters(file2_path)

print("文件1中匹配字母的数量：", file1_matching_letters)
print("文件2中匹配字母的数量：", file2_matching_letters)
