сделать функцию для установки и получения значения Redeclared 'runner' defined above without usage

Here is an example of a function in Python that sets and gets a value:

def set_value(value):
    global runner
    runner = value

def get_value():
    global runner
    return runner

# Set a value
set_value(10)

# Get the value
print(get_value())  # Output: 10

In this example, the set_value function sets a global variable runner to the given value, and the get_value function returns the current value of runner.
