从一个文件写入另一个文件

Question

以secret_msg和路径为参数
1. 以a+模式打开路径中提到的文件
2. 在上面打开的文件中写入secret_msg的内容。我该怎么做呢？它说错误

'str' object has no attribute 'write' 4. Closes the file

Returns: 该函数没有 return 个参数

message_parts=[secret_msg_3, secret_msg_1, secret_msg_4, secret_msg_2]
final_path= user_data_dir + '/secret_message.txt'

#Code starts here
secret_msg = " ".join(message_parts)
def write_file(secret_msg, path) :
    open("path" , 'a+' )
    path.write(secret_msg)
    path.close()

write_file(secret_msg,final_path)

print(secret_msg)

Answer 1

您需要 open 文件，然后调用 write 方法。

这是一种方式：

def write_file(secret_msg, path):
    f = open(path, 'a+')
    f.write(secret_msg)
    f.close()

或使用with:

def write_file(secret_msg, path):
    with open(path, 'a+') as f:
        f.write(secret_msg)

我建议你看看How to write a file with Python。
