How can I count and display the amount of times my program has been run?

I am making a text based game that once finished should write certain variables to a text file:

==============
Story0: 
-----------
Players name: name
Players characteristic: characteristic

This works fine, however what I wish to implement is a way for the function this text comes from to also display which story it is generating meaning that it would write: StoryX on the X'th time that the program has been run.

I am unfamiliar with writing to and reading from python files and I'm afraid I am very far off what would be the best solution. The following code represents what I have so far (providing an error):

def Endscript(numberofcycles):
    with open("playerstories.txt", 'a') as f:
        f.write("================\n")
        f.write("Story" + str(numberofcycles) + ": \n")
        f.write("-----------\n")
        f.write("Players name: " + Player.name)
        f.write("\n")
        f.write("Players characteristic: " + Player.char)
        f.write("\n")
    with open("number.txt", "r") as f:
        numberofcycles = f.readline()
        numberofcycles = int(numberofcycles)
        numberofcycles += 1
    with open("number.txt", "w") as f:
        numberofcycles = str(numberofcycles)
        f.write(numberofcycles)

What I have attempted to do here is to change the value of a number, (yes just one number) from within the number.txt file in accordance with the changing X value.

Thank you for any help you can provide

Is this what you mean?

def Endscript():
    with open("playerstories.txt", 'a') as f:
        with open("number.txt", "r") as file:
            numberofcycles = file.readline()
            numberofcycles = int(numberofcycles)
        f.write("================\n")
        f.write("Story" + str(numberofcycles) + ": \n")
        f.write("-----------\n")
        f.write("Players name: " + Player.name)
        f.write("\n")
        f.write("Players characteristic: " + Player.char)
        f.write("\n")
        with open("number.txt", "w") as f:
            numberofcycles += 1
            numberofcycles = str(numberofcycles)
            f.write(numberofcycles)

The error is caused by the undefined numberofcycles, if so it is because you haven't read into the txt file to retrieve the numberofcycles.

You have the right idea, just remember that each run your game will be a completely independent process so your Endscript() function really does not know the numberofcycles unless you have already read that from disk. Here is quick function to access a single file and increment the value each time, returning that value for your use.

import os

def increment_counter(file_name):
    if not os.path.exists(file_name):
        with open(file_name, 'w') as fp:
            fp.write("1")
        return 1
    else:
        with open(file_name, 'r') as fp:
            current_count = int(fp.read().strip())
        with open(file_name, 'w') as fp:
            fp.write(str(current_count + 1))
        return current_count + 1
    
fname = 'test_counter.txt'
print(increment_counter(fname))
print(increment_counter(fname))
print(increment_counter(fname))
print(increment_counter(fname))

Output:

1
2
3
4

You can couple this with a reset_counter() which just deletes the file to reset it
