How can I save a user's input and ask them if they want to use it again when restarting the program, so they don't have to enter the same thing every time they close the program?

You should store the data in some DB or JSON file, there is no way to save input data stored in a variable after closing the program.

You can use something like this. It's save user input data to config.py module, so you can use it anywhere.

import os

user_input = None  
if os.path.exists('config.py'): #check if config file exist
    ask = input("Do you want use previous data? (yes/no)")
    if ask == 'no':
        user_input = input("Some things...")
    elif ask == 'yes':
        import config
        user_input = config.last_input  # take last value of input from config file
    else:
        print("Wrong command, please anserw yes or no.")
else:
    user_input = input("Some things...")

print(user_input)

# save input
with open("config.py", "w+") as file:
    file.write(f"last_input = {user_input}")

It's easy way, not needed to use json or ini files. You can just copy&paste this, will work.
