如何在python中传递csv文件的第一列(How to pass the first column of a csv file in python)

如何在python中传递csv文件的第一列(How to pass the first column of a csv file in python)

我刚写了这段代码：

EXl = ('C:\\vd36e404.vdb','C:\\vd368c03.vdb') x=0 for x in EXl: import os filesize= os.path.getsize(x) print (filesize);

我想做的是这个。 我有一个csv文件，它在第一列中有我需要给上面程序的路径列表，然后它应该给我输出csv文件给出的路径文件的大小。

有谁知道如何编码？

I have just written this code:

EXl = ('C:\\vd36e404.vdb','C:\\vd368c03.vdb') x=0 for x in EXl: import os filesize= os.path.getsize(x) print (filesize);

What I would like to do is this. I have a csv file which has in the first column the list of path I need to give to the above program, which should then give me as output the size of the path-file given by the csv file.

Does anyone know how to code that?

我认为这适合你：

http://docs.python.org/library/csv.html

看看这个例子：

import csv spamReader = csv.reader(open('eggs.csv', 'rb'), delimiter=' ', quotechar='|') for row in spamReader: print ', '.join(row) Spam, Spam, Spam, Spam, Spam, Baked Beans Spam, Lovely Spam, Wonderful Spam

I think this would fit you :

Look at this example :

import csv spamReader = csv.reader(open('eggs.csv', 'rb'), delimiter=' ', quotechar='|') for row in spamReader: print ', '.join(row) Spam, Spam, Spam, Spam, Spam, Baked Beans Spam, Lovely Spam, Wonderful Spam
