In this example we show how to get a random element from a list using python
We will use 3 different methods to do this
random.randint(start, stop) – start and stop are required as they specify which position to start and to which position to stop.
random.choice(sequence) – sequence can be many things including a set, list, tuple, etc
random.randrange(start, stop, step) – This returns a random element from the specified range.
Example
import random #import random module mylist=[1,2,3,4,5,6,7,8,9,10] #Intialize list with integer elements print("Elements in list are:",mylist) #print the elements in the list randint=random.randint(0, len(mylist)-1) #get random element using the random.int() method randomint = mylist[randint] randomchoice=random.choice(mylist) #get random element using the random.choice() method randrange=random.randrange(len(mylist)) #get random element using the random.randrange() method randomrange= mylist[randrange] print("The random number from mylist is:",randomint) #print the random number in list print("The random number from mylist is:",randomchoice) #print the random number in list print("The random number from mylist is:",randomrange) #print the random number in list
When you run this you will see something like this
>>> %Run randomlist.py Elements in list are: [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] The random number from mylist is: 4 The random number from mylist is: 7 The random number from mylist is: 9
