为什么我能够把档案目录储存在一个变数中,供作案人使用(档案)?
原标题:Why can t I store the file directory in a variable for use with csv.reader(file())?

我需要在一个变数中储存一个档案目录,因为它稍后将使用。 在我下面的发言稿中,我要打印内容,但我只读一个<条码>。 类型Error:文档物体不可用。

文字:

posfile =  C:/Users/name/Desktop/textfile.txt 
csv_data=csv.reader(file(posfile))
count_test = 0
for row in csv_data:
    count_test = count_test + 1
    print count_test, row
最佳回答

Try:

posfile =  C:/Users/name/Desktop/textfile.txt 
csv_data=csv.reader(open(posfile,  rb ))
count_test = 0
for row in csv_data:
    count_test = count_test + 1
    print count_test, row

您也不妨检查一下,您的法典中有些地方的档案价值没有变化。

file(posfile) 

应当工作。

如果你做的是档案=某些档案。 在法典中,你可能会遇到问题。 由于档案不再是档案标的。
