Python Random modul je ugrađeni modul za generiranje nasumičnih cijelih brojeva u Pythonu. Ovi se brojevi pojavljuju nasumično i ne slijede nikakva pravila ili upute. Stoga možemo koristiti ovaj modul za generiranje nasumičnih brojeva, prikaz nasumične stavke za popis ili niz, i tako dalje.

Funkcija random().

Funkcija random.random() daje float broj u rasponu od 0,0 do 1,0. Za ovu funkciju nisu potrebni nikakvi parametri. Ova metoda vraća drugu slučajnu vrijednost pomičnog zareza unutar [0.0 i 1].

Funkcija randrange().

Funkcija random.randrange() nasumično odabire stavku iz zadanog raspona definiranog parametrima početka, zaustavljanja i koraka. Prema zadanim postavkama, početak je postavljen na 0. Isto tako, korak je prema zadanim postavkama postavljen na 1.

Funkcija choice().

Funkcija random.choice() nasumično odabire stavku iz niza koji nije prazan. U donjem programu definirali smo string, listu i skup. Korištenjem gore navedene metode choice(), odabire se slučajni element.

 # To select a random element import random random_s = random.choice('Random Module') #a string print( random_s ) random_l = random.choice([23, 54, 765, 23, 45, 45]) #a list print( random_l ) random_s = random.choice((12, 64, 23, 54, 34)) #a set print( random_s ) 

Izlaz:

Funkcija shuffle().

Funkcija random.shuffle() nasumično miješa dani popis.

Zaključak

Da zaključimo, naučili smo o raznim metodama koje nam nudi Pythonov nasumični modul za rad s cijelim brojevima, brojevima s pomičnim zarezom i drugim nizovima poput popisa, torki itd. Također smo pogledali kako početna vrijednost utječe na obrazac pseudo-nasumičnog broja.
