Mein Sohn wächst heran, also habe ich beschlossen, eine Artikelreihe über kleine Computerstreiche mit Python zu veröffentlichen 🙂 Ich habe absichtlich einen lockeren und humorvollen Schreibstil gewählt… also, liebe Leser, nehmt es mir nicht übel 🙂 Ich habe mir Mühe gegeben! Also dann…

Wie kann man einen Computer mit Python neu starten oder herunterfahren? weiterlesen →

Hallo zusammen!

Ich habe fast zwei Monate lang nicht programmiert, weil ich keine Zeit hatte. Dementsprechend ist vieles in Vergessenheit geraten, einiges ist kurz davor in Vergessenheit zu geraten 🙂 Um das Gelernte nicht völlig zu verlieren, habe ich schnell einen Rechner skizziert, der von metrischen in nicht-metrische Maße und umgekehrt umrechnet.

Es ist alles ganz einfach – if, elif, print

var = int(input('1: Metric to Imperial\n2: Imperial to Metric\n'))
if var == 1:
print('Conversion from Metric to Imperial')
conversion = int(input('What are we converting: \n 1. Temperature\n 2. Weight\n 3. Length\n 4. Volume\n 5. Speed\n '))
# Temperature conversion
if conversion == 1:
temperature = int(input(' 1. Celsius -> Fahrenheit\n 2. Celsius -> Kelvin\n'))
if temperature == 1:
value_temperature = float(input('How many degrees Celsius? :\n'))
print(value_temperature, 'degrees Celsius is', round((((9/5) * value_temperature + 32)), 2), 'degrees Fahrenheit')
elif temperature == 2:
value_temperature = float(input('How many degrees Celsius? :\n'))
print(value_temperature, 'degrees Celsius is', round((value_temperature + 273.15), 2), 'Kelvin')
# Weight conversion
elif conversion == 2:
mass = int(input(' 1. Kilograms -> Pounds\n 2. Grams -> Ounces \n'))
if mass == 1:
value_mass = float(input('How many kilograms? :\n'))
print(value_mass, 'kilograms is', round((value_mass * 2.20462), 2), 'pounds')
elif mass == 2:
value_mass = float(input('How many grams? :\n'))
print(value_mass, 'grams is', round((value_mass * 0.035274), 2), 'ounces')
# Length conversion
elif conversion == 3:
length = int(input(' 1. Kilometers -> Miles\n 2. Meters -> Yards\n 3. Meters -> Feet\n 4. Centimeters -> Inches\n 5. Millimeters -> Inches \n'))
if length == 1:
value_length = float(input('How many kilometers? :\n'))
print(value_length, 'kilometers is', round((value_length * 1.60934), 2), 'miles')
elif length == 2:
value_length = float(input('How many meters? :\n'))
print(value_length, 'meters is', round((value_length * 1.09361), 2), 'yards')
elif length == 3:
value_length = float(input('How many meters? :\n'))
print(value_length, 'meters is', round((value_length / 0.3048), 2), 'feet')
elif length == 4:
value_length = float(input('How many centimeters? :\n'))
print(value_length, 'centimeters is', round((value_length * 2.5400013716), 2), 'inches')
elif length == 5:
value_length = float(input('How many millimeters? :\n'))
print(value_length, 'millimeters is', round((value_length / 0.0393701), 2), 'inches')
# Volume conversion
elif conversion == 4:
volume = int(input(' 1. Liters -> Gallons\n 2. Liters -> Pints\n'))
if volume == 1:
value_volume = float(input('How many liters? : '))
print(value_volume, 'liters is', round((value_volume / 3.785411784), 2), 'gallons')
elif volume == 2:
value_volume = float(input('How many liters? :\n'))
print(value_volume, 'liters is', round((value_volume / 0.56826125), 2), 'pints')
# Speed conversion
elif conversion == 5:
speed = float(input('How many kilometers per hour? : '))
print(speed, 'km/h is', round((speed / 1.60934), 2), 'mph')
elif var == 2:
print('Conversion from Imperial to Metric')
