Save files in python

[Pythons]

Hey everyone,

I have just created a save feature in my game. It uses

 

sfile = open("savefile","w")

 

to open the file, and

 

with open("savefile","w") as y:
            y.write("Attack " + repr(attack) + '\n')

to write in it.
I will store variables in this file like attack and defense. I just need a function that can read it and then change the variables depending on what was in the file.
Any help would be appreciated!

If you're saving variables I'd recommend storing your stuff in json, here's a tutorial:

Hmmm, maybe.
I was thinking about just using normal python without downloading anything!

you don't have to, you can just

import json

you don't have to, you can just do this:

 

read:

 

import json
with open('JSONData.json', 'r') as f:
     data = json.load(f)
 
print(data)

 

write:

import json
 
data = {
    "name":"Pythons",
    "type":"Linus Tech Tips User"
}
 
#json.dumps() method turns a Python data structure into JSON:
jsonData = json.dumps(data)
print(jsonData)
 
# Writing JSON data into a file called JSONData.json
#Use the method called json.dump()
#It's just dump() and not dumps()
#Encode JSON data
with open('JSONData.json', 'w') as f:
     json.dump(jsonData, f)

Hey, Thanks a heap!!!

Just one last question: How do I assign these values to a variable?

So, for this example,

 

Name = "Pythons"

 

Sorry if this is a silly question, I'm not very good at python as you can see
