将文件中的参数添加到python中的给定URL

Question

I would like to generate a series of urls using given urls plus some params in a txt file.

For example, the given urls are:

http://stackoverflow.com/questions/ask1
http://stackoverflow.com/questions/ask2

They are stored in A1, A2, respectively, in Sheet1 in url.xlsx file.

The params are stored in params.txt file, with following content:

w3e
1
123456
fy

I would like to generate urls like following:

http://stackoverflow.com/questions/ask1/param.x
http://stackoverflow.com/questions/ask2/param.x

This means I will get 2x4=8 urls.

Any idea how to make this work? Many thanks!

Read both files into lists, then use itertools.product() to combine them:

from itertools import product

with open('urls.txt') as urlfile:
    urls = [line.strip() for line in urlfile]

with open('params.txt') as paramfile: parameters = [line.strip() for line in paramfile]

for url, param in product(urls, parameters):
    print url + param
