Answer:

You can make a database and save them, the only way is this. A database with SQLITE or a .txt file. For example:

with open("mylist.txt","w") as f: #in write mode

f.write("{}".format(mylist))

Your list goes into the format() function. It'll make a .txt file named mylist and will save your list data into it.

After that, when you want to access your data again, you can do:

with open("mylist.txt") as f: #in read mode, not in write mode, careful

rd=f.readlines()

print (rd)
