How can we store dynamic array values permanently

Question

I tried to store array values in python but after inserting values I close the IDE and open it prints the array values null. How can we store dynamic array values permanently in python it's like load and write values from a file.......

What you did may be obvious to you, but you need to be explicit with us. *How* did you try to store them? If your question is how to write to and read from a file, it has surely been asked before. — Reti43, Oct 21 '17 at 16:08
There are many options for writing something to a file, but the cleanest or most appropriate depends on what kind of values you have. Is it an numpy array or list? Are your values numbers, strings or objects? — Reti43, Oct 21 '17 at 16:34

You could use

json

pickle

for permanent storage.

if STORAGEFILE EXISTS:
  Var = STORAGEFILE_CONTENT
else:
  Var = currentVal
ON_EXIT:
  Update Var to STORAGEFILE

The easiest way is to write the array values to a txt-file. Then you can close your IDE and later open it and get the array from the txt-file.
