Question

我是Python编程的新手，最近我正在尝试读取csv文件，然后将该csv文件中的数据保存到文本文件中。这是我正在使用的代码

csv_file = open('example.csv', 'r')
txt_file = open('example.txt', 'w')

with open(txt_file, 'w') as my_output_file:
    with open(csv_file, 'r') as my_input_file:
        [my_output_file.write(" ".join(row)+'\n') for row in csv.reader(my_input_file)]
    my_output_file.close()

我收到此错误

File "c:\Users\Desktop\Folder\tokenizing.py", line 41, in <module>
    with open(txt_file, 'w') as my_output_file:
TypeError: expected str, bytes or os.PathLike object, not _io.TextIOWrapper

有谁知道为什么抱怨？

Answer 1

将文件名传递给open调用并使用for循环而不是list comp，并让文件对象的with context manager负责关闭文件：

csv_file = 'example.csv'
txt_file = 'example.txt'

with open(txt_file, 'w') as my_output_file:
    with open(csv_file, 'r') as my_input_file:
        for row in csv.reader(my_input_file):
            my_output_file.write(" ".join(row)+'\n')

Python csv文件标记化
