python - List index out of range and random number to choose an item in list -

i need make list of iphone models string using .split().

that's not problem, have use random number 0-9 pick word, display 3 random words using while/for loop.

in code, when enter:

import random  iphone = 'original 3g 3gs 4 4s 5 5c 5s 6 6plus'.split()  z = 0 while z < 4:     y in range (1,3):         x in iphone:             x = random.randint(0,9)             print (iphone[x]) 

it says:

 traceback (most recent call last):       file "c:\users\zteusa\documents\az_wordlist2.py", line 15, in <module>         print (iphone[x])     indexerror: list index out of range 

i'm not sure whats causing this.

both arguments random.randint inclusive:

>>> import random >>> random.randint(0, 1) 1 >>> random.randint(0, 1) 0 >>> 

so, when x = random.randint(0,10), x equal 10. list iphone has ten items, means maximum index 9:

>>> iphone = 'original 3g 3gs 4 4s 5 5c 5s 6 6plus'.split() >>> len(iphone) 10 >>> iphone[0]  # python indexes start @ 0 'original' >>> iphone[9]  # max index 9, not 10 '6plus' >>> iphone[10] traceback (most recent call last):   file "<stdin>", line 1, in <module> indexerror: list index out of range >>> 

you need do:

x = random.randint(0, 9) 

so x within range of valid indexes iphone.

regarding comments, said need print 3 random items list. so, this:

import random  iphone = 'original 3g 3gs 4 4s 5 5c 5s 6 6plus'.split()  z = 0 while z < 3:     x = random.randint(0,9)     print (iphone[x])     z += 1  # remember increment z while loop exits when should
