i tried make program take amount of elements , randomly generate them. example, user enter twenty names , have algorithm spit them out randomly. built program in such way enter twenty elements, , print out number plus 1 random things. enter twenty elements , randomly choose them twenty-one times. problem i'm not experience random, made ridiculously large (just shy of 500 lines). works, i'd like: 1) shortened. 2) take number, rather between 2 , 20 , 3) able spit out user-entered number of random items. don't know if of made sense, if can! whole massive code:
import random = input('enter number of elements(maximum twenty).\n') if < 2 or > 20: print('restart program , enter value between 2 , twenty.') if(a == 2): 1 = raw_input('enter first element.\n') 2 =

yes! there simple way. if notice, number, n, make n actions, can simplified loop.
import random n = int(raw_input('number: ')) items = raw_input('items: ').split() choices = [random.choice(items) _ in xrange(n)] print choices i've made can input items in 1 go space delimeter, that's can change. when run it, get
number: 5 items: '1 4 6 56 45 34 7 12 fgtr hyt 98 0 98 78 6666666666.6' ['56', '98', "6666666666.6'", '7', 'fgtr'] now, see in many questions, trusting input user give not wise idea, wrap input number in try statement , repeat many times necessary until integer.
while true: try: n = int(raw_input('number: ')) break except valueerror: print 'gimme integer please!' another thing, if want list have many items number, can use loop that.
items = [raw_input('input item number {}'.format(i+1)) in xrange(n)]
