with open('variable.txt', 'w') as file:
    file.write('Hello, World!')

with open('variable.txt', 'r') as file:
    my_variable = file.read()
print(my_variable)  # Output: Hello, World!

# variables.py
my_variable = 'Hello, World!'

import variables
variables.my_variable = 'Hello, World!'

import variables
