python脚本替换文件中的字符串

可以使用以下的Python脚本来替换文件中的字符串：

def replace(file_path, old_str, new_str):
    f = open(file_path, 'r+')
    all_lines = f.readlines()
    f.seek(0)
    f.truncate()
    for line in all_lines:
        line = line.replace(old_str, new_str)
        f.write(line)
    f.close()

replace(file_path, old_str, new_str)

这个脚本会打开指定的文件，逐行读取文件内容，并将需要替换的字符串替换为新的字符串，然后将修改后的内容写回文件中。你只需要调用`replace`函数，并传入文件路径、需要被替换的字符串和新的字符串作为参数即可。请确保文件路径是正确的，并且你有足够的权限来读取和写入该文件。
