f = open('attendees1.csv')

只要我的程序文件和csv文件在同一目录中即可.但是，如何提供指向另一个目录中的csv文件的链接?

As long as my program file and csv file is in the same directory. But how do I provide a link to the csv file sitting in another directory?

我有一个包含多行和多列的列表，如何将这些数据传输到csv文件并将其保存在特定位置?

I have a list with multiple rows and columns, how do I transfer this data to a csv file and save it down in a particular location?

答

open() 是文件，可以是诸如C:\Program Files\file.csv的绝对路径，也可以是诸如../../file.csv的相对路径，此处..指当前目录上方的目录，而.指当前目录

First argument of open() is file, which can be an absolute path like C:\Program Files\file.csv or a relative one like ../../file.csv here .. refers to the directory above the current directory and . refers to the current directory.

import csv
with open('../path/to/file.csv', 'w') as f:
    csv_writer = csv.writer(f)
    csv_writer.writerows(your_row_data)

your_row_data是列表列表.
