Code:
data = {
    "PLAYER":name,
    "STRENGTH": strength,
    ...
}

with open("data1.txt", "w", encoding="utf-8") as file:
   file.write(repr(data))
file.close()

I am using this to write in to a external file "data1.txt" but what happen if want to change or replace for example 'STRENGTH:' after a certain action..

So if the output file is ORIGNALLY {'STRENGTH': '100'}... how do i change or replace the value of 100 to a different number?

The data is in string format.
