Wald oder Bäume

Wann soll man Details einer Funktion in Unterfunktionen extrahieren, weil man ansonsten "den Wald vor lauter Bäumen nicht sieht"?

Und wann soll man lieber die Details sichtbar lassen?

Welches sind die Vor- und Nachteile ​​der folgenden Beispiele und welches favorisiert ihr?

1. Alle Details

import sys

def main():
    numbers = [int(argument) for argument in sys.argv[1:] if str.isnumeric(argument)]

    for i in range(0, len(numbers)):
        for j in range(1, len(numbers) - i):
            if numbers[j] < numbers[j - 1]:
                numbers[j-1:j+1] = [numbers[j], numbers[j - 1]]

    print(', '.join([str(number) for number in numbers]))

if __name__ == '__main__':
    main()

2. Alle Details mit Kommentaren

import sys

def main():
    #Read numbers from command line
    numbers = [int(argument) for argument in sys.argv[1:] if str.isnumeric(argument)]

    #Sort numbers
    for i in range(0, len(numbers)):
        for j in range(1, len(numbers) - i):
            if numbers[j] < numbers[j - 1]:
                numbers[j-1:j+1] = [numbers[j], numbers[j - 1]]

    #Write numbers to console
    print(', '.join([str(number) for number in numbers]))

if __name__ == '__main__':
    main()

3. Drei Unterfunktionen mit konkreten Namen

import sys

def main():
    numbers = readNumbersFromCommandLine()
    sort(numbers)
    writeNumbersToConsole(numbers)

def readNumbersFromCommandLine():
    return [int(argument) for argument in sys.argv[1:] if str.isnumeric(argument)]

def sort(numbers):
    for i in range(0, len(numbers)):
        for j in range(1, len(numbers) - i):
            if numbers[j] < numbers[j - 1]:
                numbers[j-1:j+1] = [numbers[j], numbers[j - 1]]

def writeNumbersToConsole(numbers):
    print(', '.join([str(number) for number in numbers]))

if __name__ == '__main__':
    main()

4. Drei Unterfunktionen mit allgemeinen Namen

import sys

def main():
    numbers = getNumbers()
    sort(numbers)
    setNumbers(numbers)

def getNumbers():
    return [int(argument) for argument in sys.argv[1:] if str.isnumeric(argument)]

def sort(numbers):
    for i in range(0, len(numbers)):
        for j in range(1, len(numbers) - i):
            if numbers[j] < numbers[j - 1]:
                numbers[j-1:j+1] = [numbers[j], numbers[j - 1]]

def setNumbers(numbers):
    print(', '.join([str(number) for number in numbers]))

if __name__ == '__main__':
    main()
