Better than an array

[oldcity]

Using Linux Mint 18.2 and Python 3.5.2 as before I'm old school basic.
Need help with this array type problem.

What is your question / problem?

You can use enumerate as a counter:

1 2 3 4

for lcnt, line in enumerate(catgs, 1) :     dfiles = line.strip(",")     dcatagory = dfiles.rstrip("\n")     mcatg[lcnt] = dcatagory

As mentioned earlier my lifetime programming language was Basic.
I ran a test of your suggestion and it gives an error message I have
no idea how to deal with.
Any suggestion most helpful.

#!/usr/bin/python3 dcatagory = '' lcnt = 0 with open('COL-HDRS-Sel4', 'r') as catgs:     for lcnt, line in enumerate(catgs, 1) :         dfiles = line.strip(",")         dcatagory = dfiles.rstrip("\n")         mcatg[lcnt] = dcatagory           catg = 5  # catg value to be assigned later print ("\n") print(mcatg[catg]) print("bye ")

Code produces this error message.

1 2 3 4 5

@oldcity ~/MyPython $ python3 fix-here Traceback (most recent call last):   File "fix-here", line 8, in <module>     mcatg[lcnt] = dcatagory @oldcity ~/MyPython $

It's a name error. You have not defined mcatg before that point, so you can't index it. If this is meant to be a list, you should define it as mcatg = [], and use append: mcatg.append(dcategory). If it is meant to be a dictionary you would define it as mcatg = {}, but then you don't need to make any other changes to the code.
