I made a simple text fighting game.but i need to be able to save and load variables.i was tols to use pickle. But i have no experience in what it even is.i googled arouns but i can't understand how it works
Basicly i have some variables
And need to save them to a file.then load them

name=str(jonathan)
Damage=int(10)
# and so on and ao forth.these variablea change depending on level.i need to be able to save them to a file which is named (name).so here it will be called jonathan.later read these variables and set health and such accordingly to continue playing.simple things as im really new

Don't use pickle,use Json is't just better and you get human readable file on disk.
Data serialization is the concept of converting structured data into a format that allows it to be shared,
or stored in such a way that its original structure to be recovered.

Instead of storing stuff in singe variables think of a data structure like eg dictionary.

>>> record = dict(name='jonathan', Damage=10)
>>> record
{'Damage': 10, 'name': 'jonathan'} 

import json

record = dict(name='jonathan', Damage=10)
with open("my_file.json", "w") as j:
   json.dump(record, j)
with open("my_file.json") as j_out:
   saved_date = json.load(j_out)

print(saved_date) #--> {'Damage': 10, 'name': 'jonathan'}
