Anytime you use eval, chances are that it isn't fixed at all, but just

Hey all,
It's mostly solved. The program prints out to the screen just fine except
for the new line return. Here is what I ended up using:
#Merges two files into one using dictionaries
xml = open("final.txt",'r')
gen = open("final_gen.txt",'r')
PIDS = {}
for proteinVals in g
I sent both emails and may have confused things:
1. PIDS.has_key(ID) returns True/False. you need to make sure the dictionary
has the key before you fetch PIDS[NotAKey] and get a KeyError.
2. line.split() splits at and removes whitespace, leaving commas.
line.split(",") splits at and removes comma

Morning all,
I took the pseudocode that Emile provided and tried to write a python
program. I may have taken the pseudocode to literally.
So what I wrote was this:
xml = open("final.txt",'r')
gen = open("final_gen.txt",'r')
PIDS = {}
for proteinVals
"join" operates on lists. It "joins" the elements of the list using the
leading character or string as the delimiter. In this case it is NUL.
Try putting a character or string, like 'XX\n' in front of the ".join" in
both places. It should illustrate what's really happening.
"XX\n".jo

some lines I changed:

for root, folde
Ok, now I see what I did. Legacy from when the get_rain_data function

It works perfectly now. Thanks for all the help.
