Python3 讀取 utf8 檔案

紀錄一下，每次都忘記 Orz

預設的話不是 utf8 讀檔案，所以會噴類似這樣的錯誤訊息

File “/usr/lib/python3.6/encodings/ascii.py”, line 26, in decode
return codecs.ascii_decode(input, self.errors)[0] UnicodeDecodeError: ‘ascii’ codec can’t decode byte 0xe9 in position 29: ordinal not in range(128)

解法就是開啟檔案時加上encoding=”utf-8″。

with open(os.path.join("./", inputfile), "r", encoding="utf-8") as my_file:
    tree_text = my_file.read()
