This is the error I get when I try running a certain program. The fun part is the program runs successfully in Windows but displays this error in Ubuntu.
I even tried updating the python from 2.7 to 3.5.
Please help me! :)
Posting the code would be helpful.
you can not really expect we can help without seeing your code. Please post your code (small snippet that reproduce the error) in python tags, as well as full Traceback in error tags.
Sorry for the trouble!
This is the code!

the netlist is :

I used glob because there will be more files in there (in the future) only with a small difference.
Put print function after line 8 to see what glob() returns

print(files)
Check the values of point, ind2
Print them too before the if statement
I would also print len(files) and point.

note that dict is built-in function, so better choose another name not to overwrite the built-in function
