Lepší, ale pořád ne optimální

In [ ]:

a = float(input('Prvni cislo: '))
b = float(input('Druhe cislo: '))
c = float(input('Treti cislo: '))
d = float(input('Ctrvte cislo: '))
e = float(input('Pate cislo: '))


m = a

for cislo in a, b, c, d, e:
  if cislo < m:
      m=cislo
print(m)

Kratší a méně náročné řešení

In [ ]:

minimum = 0
for x in range(5):
    cislo = int(input('Zadej cislo: '))
    
    if minimum == 0 or cislo < minimum:
        minimum = cislo

print('Nejmensi zadane cislo je', minimum)

Obecné připomínky a rady

K importům:
- Importy provádíme vždy na prvních řádcích programu a v rámci programu pouze jednou.
- Snažíme se nepoužívat importy s hvězdičkou.
- Neimportujeme nic co pak v programu nepoužijeme.
Ke komentářům:
- Nezakomentováváme programy nebo jednotlivé úlohy v nich.
- Není třeba psát komentáře k tomu, co je zcela jasné. Je to ale pořád lepší než je nepsat vůbec.
- Komentáře je lepší a jednodušší psát nad nebo pod kód místo vedle něj. Obzvlášť pokud má komentovaná část kódu několik řádků.
Ke stylu:
- Zkuste nedělat extra dlouhé řádky. Maximum je takových 100 znaků.
- Kód nemusí být elegantní, hlavně když funguje (alespoň pro začátek).
Martin děkuje všem, kteří zrychlili želvičku.
