Print begin and end of code section

[Benjamin-Loison]

def printState(functionLabel, state):
    print(f'{functionLabel}: {state}')

def printBeginAndEnd(function, functionLabel):
    printState(functionLabel, 'begin')
    function()
    printState(functionLabel, 'end')

myVariable = 42

def function():
    print(f'{myVariable=}')

printBeginAndEnd(function, 'Print `myVariable`')

Print `myVariable`: begin
myVariable=42
Print `myVariable`: end

Preferably would like a scheme like with:

with open('file.txt') as myFile:
    lines = myFile.read().splitlines()
    print(lines)

So without declaring a function, so something like:

myVariable = 42

beginAndEnd 'Print `myVariable`':
    print(f'{myVariable=}')

Print `myVariable`: begin
myVariable=42
Print `myVariable`: end
