写入 CSV：“UnicodeDecodeError：‘charmap’编解码器无法解码字节

Question

我试图将一个大的 csv 文件拆分成多个文件，为此我使用了这个代码片段。我正在使用 Python 3.7.7 并且在 Windows 操作系统上。我尝试添加 utf8 编码，但它仍然不起作用。你知道为什么吗？这是我的代码：import osdef split(filehandler, delimiter=',', row_limit=125000, output_name_template='jokes_%s.csv', output_path='.', keep_headers=True):    """    Splits a CSV file into multiple pieces.    A quick bastardization of the Python CSV library.    Arguments:        `row_limit`: The number of rows you want in each output file. 10,000 by default.        `output_name_template`: A %s-style template for the numbered output files.        `output_path`: Where to stick the output files.        `keep_headers`: Whether or not to print the headers in each output file.    Example usage:        >> from toolbox import csv_splitter;        >> csv_splitter.split(open('/home/ben/input.csv', 'r'));    """    import csv    reader = csv.reader(filehandler,  delimiter=delimiter)    current_piece = 1    current_out_path = os.path.join(         output_path,         output_name_template  % current_piece    )    print(current_out_path)    current_out_writer = csv.writer(open(current_out_path, 'w', encoding='utf8', newline=''), delimiter=delimiter)    current_limit = row_limit    if keep_headers:        headers = next(reader)        current_out_writer.writerow(headers)    for i, row in enumerate(reader):        if i + 1 > current_limit:            current_piece += 1            current_limit = row_limit * current_piece            current_out_path = os.path.join(               output_path,               output_name_template  % current_piece            )            print(current_out_path)            current_out_writer = csv.writer(open(current_out_path, 'w', encoding='utf8', newline=''), delimiter=delimiter)            if keep_headers:                current_out_writer.writerow(headers)        current_out_writer.writerow(row)split(open('jokes.csv', 'r'))

Answer 1

split(open('jokes.csv', 'r'))你可以换个split(open('jokes.csv', 'r', encoding="utf8"))试试。
