All you need to do to remove a file is call os.remove()
Example:

import os
os.remove("ChangedFile.csv")
print("File Removed!")

How to resume a file download in Python 3?

I would like to download a file. If the connection is OK, I can download the file with:

import urllib.request
urllib.request.urlretrieve(remote_file, local_file)

Sometimes when I am connected on week wireless (not mine) network I get WinError 10054 exception (windows 7). When it happens, I would like to resume download instead of doing everything from very beginning.

How to do that? I read about Range header and chunks, but this server doesn't have any headers.
What options do I have with this particular file?

How to find items in csv file A and not in file B and vice versa using python

Let's say I want to compare two csv files: file A and file B. They are both similarly built - the first column has product IDs (one product per row) and the columns provide some stats about the products such as sales in # and $.

I want to compare these files - see which product IDs appear in the first column of file A and not in B, and which in B and not A.
Finally, it would be very great if the result could be written into two new CSV files - one product ID per row in the first column. (no other data in the other columns needed)

This is the script I tried:

import csv

#open CSV's and read first column with product IDs into variables pointing to lists
A = [line.split(',')[0] for line in open('Afile.csv')]
B = [line.split(',')[0] for line in open('Bfile.csv')]

#create variables pointing to lists with unique product IDs in A and B respectively 
inAnotB = list(set(A)-set(B))
inBnotA = list(set(B)-set(A))

print inAnotB
print inBnotA

c = csv.writer(open("inAnotB.csv", "wb"))
c.writerow([inAnotB])

d = csv.writer(open("inBnotA.csv", "wb"))
d.writerow([inBnotA])

print "done!"

But it doesn't produce the required results.
It prints IDs in this format:

247158132n

and nothing to the csv files.
