Returning a List to a Function -
import random def genlist1(): list1 = [x x in range(100)] count = 0 count in list1: print(random.randint(2,25), end = " ") return def main(): print(genlist1()) main() the above code- prints 100 random digits between 2 , 25, returns "none" function. how can return list of 100 random digits function in following code.
import random def genlist1(): list1 = [x x in range(100)] count = 0 count in list1: random.randint(2,25) return list1 def genlist2(): list1 = genlist1() list2 = [x**2 x in list1 if x % 2 == 0] return list2 def genlist3(): list2 = genlist2() list3 = [0.5*x x in list2] return list3 def gensum1_2(): list2 = genlist2() list3 = genlist3() sum1 = 0 number1 = 0 number1 in list2: sum1 = sum1 + number1 sum2 = 0 number2 = 0 number2 in list3: sum2 = sum2 + number2 return sum1, sum2 def main(): print("here list 1, contains 100 random digits between 2 , 25: ") print(genlist1()) print(), print() print("here list 2, cubes of digits in list 1: ") print(genlist2()) print(), print() print("here list 3, digits in list 2 divided in half: ") print(genlist3()) print(), print() print("here sum of digits in list 2, , digits in list 3: ") print(gensum1_2()) main() i have tried few different alterations such adding return in front of print(random....) tried assigning print(random.....) variable returning variable...with no avail.
import random def getrandlist(): return [random.randint(2,25) x in xrange(100)] print getrandlist() or, if want behave more original code...
import random def genlist1(): randlist = [random.randint(2,25) x in xrange(100)] elem in randlist: print(elem, end = ' ') return randlist def main(): print(genlist1()) main() edit (to account question in comments below):
if want reuse random numbers in list, you've got few options.
option 1: best option
pass list in argument subsequent functions.
def genlist2(input_list): list2 = [x**2 x in input_list if x % 2 == 0] return list2 def main(): list1 = genlist1() list2 = genlist2(list1) option 2: bad programming practice
if want developer other people on team hate, can things lot:
def genlist1(): global randlist randlist = [random.randint(2,25) x in xrange(100)] elem in randlist: print(elem, end = ' ') return randlist def genlist2(): list2 = [x**2 x in randlist if x % 2 == 0] return list2 def main(): list1 = genlist1() list2 = genlist2()
