My Python Array Resets Every Time I Run it

Question

The array journal is set to empty automatically.

import os
import time
journal=[]
x=input()
for word in x:
    os.system('clear')
    print word,
else:
    print ""
    journal.extend(x)
    print journal

What is the actual question? It's good to know that _"The array journal is set to empty automatically"_ though. — AGN Gazer, Nov 09 '17 at 01:43
Also, your code makes no sense and therefore it is very difficult to understand what you wanted to achieve and therefore it is difficult to help you (or how to fix it). One thing I can say is that `else` usually follows an `if` and not a `for`. — AGN Gazer, Nov 09 '17 at 01:45
@AGNGazer The else statement executes at the end of the for loop. — Nathan Tibbitts, Nov 09 '17 at 15:40

Assuming you run this code through the python interpreter your array (they're lists in python, arrays can be created using python modules) will be removed from memory when the script ends, you will need to save the values to a file or through some other method. You could try to add a while loop to the code in order to keep prompting the user to input until they quit the program.

As a side note; even if the array was still saved to local memory when the script ended, you are resetting the list in the first line journal=[].

How would I make it so it saves, though, because deleting it would throw an error. – Nathan Tibbitts Nov 09 '17 at 15:51
You can create a text file and store the variable within that file – S. Allen Nov 10 '17 at 10:35

You have to save the information somehow if you’d like to have data persistency. Use the pickle module and create a file for the data to be stored and look up the docs for pickle for how to read and write.
