Question

Here is a beginners question:

I made a function that reads a txt file (selected by the user) and makes a list of many numbers contained in the file, called A. I called this function open_file.
Then I want to change the name of that list with the original name of the file, plus “_values“

My try

file_name = raw_inpunt('Give the name of the file:') # the user chooses the file
open_file (file_name) #A list is created

file_name +'_'+'values' = A

This doesn’t seem to work. Any ideas?

Answer 1

You can try using:

vars()[file_name+"_values"] = A

The reason it is not working because you are trying to save a list in a string.

Basically file_name+"_"+"values" is a string a not a variable. Hence you will get an error.

However I would highly suggest you saving the list of values for each filename in a dictionary.

values = dict()
values[file_name] = A

This is a more efficient way of storing values.
