在文本文件的每一行中将一个字符与另一个字符更改第n次

def change_characters(line, n):
    new_line = ""
    for i in range(len(line)):
        if i % n == 0:
            new_line += chr(ord(line[i]) + 1)  # 将字符与另一个字符更改
        else:
            new_line += line[i]
    return new_line

file_path = "path/to/your/file.txt"  # 文件路径
n = 3  # 更改次数

with open(file_path, "r") as file:
    lines = file.readlines()

new_lines = []
for line in lines:
    new_line = change_characters(line.strip(), n)
    new_lines.append(new_line)

with open(file_path, "w") as file:
    file.write("\n".join(new_lines))
