使用python讀取CSV文件時的編碼問題

Question

嘗試使用python讀取CSV文件時遇到障礙。

更新：如果您只想跳過字符或錯誤，可以打開文件，如下所示：

with open(os.path.join(directory, file), 'r', encoding="utf-8", errors="ignore") as data_file:

到目前為止，我已經嘗試過了。

for directory, subdirectories, files in os.walk(root_dir):
    for file in files:
        with open(os.path.join(directory, file), 'r') as data_file:
            reader = csv.reader(data_file)
            for row in reader:
                print (row)

我得到的錯誤是：

UnicodeEncodeError: 'charmap' codec can't encode characters in position 224-225: character maps to <undefined>

我努力了

with open(os.path.join(directory, file), 'r', encoding="UTF-8") as data_file:

錯誤：

UnicodeEncodeError: 'charmap' codec can't encode character '\u2026' in position 223: character maps to <undefined>

現在，如果我只打印data_file，它說它們是cp1252編碼的，但是如果我嘗試

with open(os.path.join(directory, file), 'r', encoding="cp1252") as data_file:

我得到的錯誤是：

UnicodeEncodeError: 'charmap' codec can't encode characters in position 224-225: character maps to <undefined>

我也嘗試了推薦的套餐。

我得到的錯誤是：

UnicodeEncodeError: 'charmap' codec can't encode characters in position 224-225: character maps to <undefined>

我要解析的行是：

2015-11-28 22:23:58,670805374291832832,479174464,"MarkCrawford15","RT @WhatTheFFacts: The tallest man in the world was Robert Pershing Wadlow of Alton, Illinois. He was slighty over 8 feet 11 inches tall.","None

任何想法或幫助表示贊賞。

我會使用csvkit ，它使用自動檢測適當的編碼和解碼。 例如

import csvkit
reader = csvkit.reader(data_file)

正如聊天解決方案中所討論的那樣-

for directory, subdirectories, files in os.walk(root_dir): 
    for file in files: 
        with open(os.path.join(directory, file), 'r', encoding="utf-8") as data_file: 
            reader = csv.reader(data_file) 
            for row in reader: 
                data = [i.encode('ascii', 'ignore').decode('ascii') for i in row] 
                print (data)
