Question

运行此代码时，由于字符串末尾的\ n，我收到错误。我该如何解决这个问题？

import urllib
prefix = 'http://archive.outernet.is/'
with open(!file_list.txt, 'r') as f:
    stock = f.read().splitlines()
    for l in stock:
        l = l.strip()
        content =   ("%s%s") % (prefix, l)
        print(content)
        urllib.request.urlretrieve(content, l)

文件列表包含

1.zip
2.zip
3.zip

错误代码类似于

Errno 2, no such file or directory 'website.ca/1.zip\n'

Answer 1

从每一行中删除空格：

for l in stock:
    l = l.strip()
    content =   ("%s%s") % (prefix, l)
    # etc. ...

Answer 2

这是我正在运行的代码。

import urllib.request

prefix = 'http://archive.outernet.is/'
with open("input.txt", 'r') as f:
    stock = f.read().splitlines()
    for l in stock:
        content = ("%s%s") % (prefix, l)
        print(content)
        print(urllib.request.urlretrieve(content, l))

输出：

http://archive.outernet.is/003669cf61a1f17115b0bf74256114ea.zip

因为\ n而无法使用字符串？
