我正在編寫一個程序來讀取一首歌曲的mysql表格，並在youtube上找到該歌曲。我想下載該歌曲並將其放在我的soundcloud帳戶上。我試圖爲此編寫代碼。問題是，我每次運行它的時候，我得到了以下問題：編碼問題-python
Non-ASCII character '\xe2' in file on line 164, but no encoding declared
請幫助解決一樣。

[Python「SyntaxError：文件」中的非ASCII字符'\ xe2']的可能重複（http://stackoverflow.com/questions/21639275/python-syntaxerror-non-ascii-character-xe2-in-文件） –
對不起，我沒有時間仔細查看你的代碼，但這很可能是unicode的問題。您可能需要在某處編碼一個unicode字符串，可能只需使用'string.encode'（'utf8'，'replace'）'。看看這裏：https：//pythonhosted.org/kitchen/unicode-frustrations.html。 –
就這麼你知道，我在'cursor.execute'行看到一個錯誤，你只需要'artist_final（'utf-8'）''這需要'artist_final.encode'（'utf-8'）'。 – CasualDemon
