May need to be in oepn function parameters and encoding="utf-8" or encoding="GBK encoding specified file

Didn't understand that, a great god

The for loop a indentation

refer to the second floor suao123 response:

Read the file, and then use the generator expressions (char for char string if in word (char) & lt; 128) filtering (including word (char) & lt; 128 is condition), only the ASCII characters in English, because the generator expressions do not return a string, so using '. Connect the join, converted to a string, and then written to the output file

You are not understand don't understand that part or all,
The problem solving steps I write to you:

3. The filtered words written text
