Question

我想使用python的3模块写入csv。但是，我没有找到任何文档可以告诉我如何传递编码参数。

我的代码：

for item in list_documents:
    print("The item is: ", item)
    wb = openpyxl.load_workbook(path+item)
    sh = wb.get_active_sheet()
    split_item = item.split(".")[0]
    new_name = str(split_item) + ".csv"
    with open(path + new_name, 'w', newline="") as f:
        c = csv.writer(f, delimiter=";")
        counter = 0
        for r in sh.rows:
            counter += 1
            print(counter)
            c.writerow([cell.value for cell in r])

我的代码从xlsx文件读取行并将其放入csv。对于csv.writer，我似乎无法指定我想要UTF-8编码。

错误消息：

Traceback (most recent call last):
  File "C:/Users/aprofir/Desktop/python_project/transform_data/xlsx_to_csv.py", line 31, in <module>
    c.writerow([cell.value for cell in r])
  File "C:\Users\aprofir\AppData\Local\Programs\Python\Python37-32\lib\encodings\cp1252.py", line 19, in encode
    return codecs.charmap_encode(input,self.errors,encoding_table)[0]
UnicodeEncodeError: 'charmap' codec can't encode character '\u0142' in position 173: character maps to <undefined>

据我了解，字符\u0142表示波兰字母ł。我有办法解决这个问题吗？我无法删除或更改数据。

您可以在此处打开文件时指定编码：

with open(path + new_name, 'w', newline="", encoding='utf-8') as f:

如何为csv.writer指定编码类型？
