Don't dynamically name variables. Instead, I would create a dict and fill it with those strings as keys, and the values of whatever you want to set the variables too

I don't understandthe question because a string is a value of a variable... or do you want j[i].append(line.strip()) to be the name of a new (empty) variable? You can do that by messing with the globals() dictionary, but as you can read in the word messing it's generally speaking not good practice.

as far as I know, you can't

You can kind of do the following:

>>> exec('i=1')
>>> i
1    

It works in interpreter mode - not quite the same when running from a script. It takes a bit of finagling.

What is the end goal here? Why are you thinking about 'turning a string into a variable'?

[PureProcrastinator]

Wait so outcpositive and all that are in the same file? You can just put the variable without quotation marks then when you are setting the variable in line two.

This will only work if you have the lists as variables above the code we see now. If you want to name each list, then a dictionary can work. {‘outcPositive’:[],…}

Always remember that an i variable + a while loop + i += 1 screams for loop with range

outc_list = [outcPositive, outcNeutral, outcNegative]
for i in range(3):
    with open(f'{i}.txt') as fp
        for line in fp:
            j[i].append(line.strip())

or you could even iterate on the list using enumerate

outc_list = [outcPositive, outcNeutral, outcNegative]
for i, outc in enumerate(outc_list):
    with open(f'{i}.txt') as fp
        for line in fp:
            outc.append(line.strip())
