Python批量将csv文件编码方式转换为UTF-8_python 如何写utf8的csv

import os
import pandas as pd
import chardet


def convert_encoding(file_path, file_encoding):
    # try:
    # 读取文件
    with open(file_path, 'rb') as f:
        data = f.read()
        # 检测文件编码方式
        file_encoding = chardet.detect(data)['encoding']
        print(file_encoding)
    # 重新编码文件
    if file_encoding != 'utf-8':
        df = pd.read_csv(file_path, sep=None, encoding=file_encoding, engine='python')
        df.to_csv(file_path, sep=',', encoding='utf-8', index=False)
    # except Exception as e:
    #     print('Error:', e)


def encoding_transform(folder_path, file_ext):
    # 遍历文件夹下所有文件
    for file_name in os.listdir(folder_path):
        file_path = os.path.join(folder_path, file_name)
        # 如果是csv文件
        if os.path.isfile(file_path) and os.path.splitext(file_path)[1] == '.' + file_ext:
            convert_encoding(file_path, 'utf-8')


encoding_transform(r'D:\csv_test', 'csv')

在用office打开时，可能会出现乱码的情况，将encoding='utf-8'变成encoding='utf_8_sig'即可
