Zvířátka
Najdi chyby, nejasnosti či nepřesnosti v tomto kódu:
In [ ]:
zvirata = [ "pes", "kočka", "králík", "had", "ježek"]
znak = "k"
def pismeno(jmeno):
for i in range(5):
if znak in jmeno[i][0]:
print(jmeno[i])
return
pismeno(zvirata)
Takto by to mohlo vypadat přehlednější a pochopitelnější
In [ ]:
zvirata = [ "pes", "kočka", "králík", "had", "ježek"]
def s_prvnim_pismenem(seznam_zvirat, pismeno):
for zvire in seznam_zvirat:
if zvire.startswith(pismeno):
print(zvire)
s_prvnim_pismenem(zvirata, 'k')
Další podobná funkce:
In [ ]:
def kratke(jmeno = zvirata):
for i in range(len(jmeno)):
if len(jmeno[i]) < 5:
print(jmeno[i])
else:
print(end = "")
return jmeno
kratke(zvirata)
A její přehlednější varianta:
In [ ]:
def kratke(seznam_zvirat):
for jmeno in seznam_zvirat:
if len(jmeno) < 5:
print(jmeno)
kratke(zvirata)
Je možné tuto funkci zkrátit a zjednodušit?

Funkce jako stavební blok programu
Takto použitá funkce situaci spíše komplikuje, než aby něčemu pomohla.

seznam2.sort()
for item in seznam2:
seznam3.append(item[1])

Co se asi stane, když takovou funkci zavoláme vícekrát?

razeni_had(zvirata, dvojice, vysledek)

Ověření, že funkce funguje
Nejsnazší je funkci prostě spustit s různými argumenty a podívat se, zda dělá to, co by dělat měla.

Rubber duck problem solving
Jde o techniku řešení problému, při které se svůj problém snažíte vysvětlit někomu (nebo v případě gumové kachny něčemu), kdo programování nemusí vůbec rozumět. Když řešenou problematiku a vaše současné řešení popisujete nahlas, uvědomíte si, co váš program aktuálně dělá a co by dělat měl, což zpravidla vede k vyřešení problému.
Obecné rady a poznatky
Snažte se!!!
