What I am essentially looking for is the `paste' command in bash, but in Python2. Suppose I have a csv file:

a1,b1,c1,d1
a2,b2,c2,d2
a3,b3,c3,d3

And another such:

e1,f1
e2,f2
e3,f3

I want to pull them together into this:

a1,b1,c1,d1,e1,f1
a2,b2,c2,d2,e2,f2
a3,b3,c3,d3,e3,f3

This is the simplest case where I have a known number and only two. What if I wanted to do this with an arbitrary number of files without knowing how many I have.

I am thinking along the lines of using zip with a list of csv.reader iterables. There will be some unpacking involved but seems like this much python-foo is above my IQ level ATM. Can someone suggest how to implement this idea or something completely different?

I suspect this should be doable with a short snippet. Thanks.

file1 = open("file1.csv", "r")
file2 = open("file2.csv", "r")for line in file1:print(line.strip().strip(",") +","+ file2.readline().strip()+"\n")

Extendable for as many files as you wish. Just keep adding to the print statement. Instead of print you can also have a append to a list or whatever you wish. You may have to worry about length of files, I did not as you did not specify.
