I've got about 6 *.csv files that I am trying to open; change the header names (to get rid of spaces); add two new columns, which are just the results of a string.split() command; drop the column I just split; and then finally export to *.txt files. Here's the code I'm using:

Its generally a good idea in programming to separate separable problems. Since you say:

you should probably write and have checked the code that handles one file. For example a function that takes as parameters the two: the input/output files (maybe names or handles), and then
- check that that function works for one file
- call it in your loop

[BTW your code seems to mixup the variable-names for file-names and handles]
