[Tutor] Cube root

[Amanda Colley]

Ok, I have to get input from a user  ('enter a number') and then get the
cube root of that number.  I am having trouble with the code to get the
cube root. If anyone can help me solve this I would greatly appreciate it.
('enter a number')
n=number

[Tutor] using the loop function while another

[Amanda Colley]

Ok, here is my problem.  If a person has two  different people to order
books for, then when using the loop option, How do you add the two seperate
choices together for a  final total of books cost?

 another='y'
while another=='y' or another=='Y':
choice()
another=input('Do you have another book to order for this student?
'+\
  'Enter y for yes: ')

def choice():
book=int(input('Enter the book chioce you want: ' +\
   'For Hardback Enter the number 1: ' +\
   'Paperback Enter the number 2: ' +\
   'Electronic Enter the number 3: '))
num=int(input('Enter how many you need: '))
cost=0
if book==1:
cost=79
elif book==2:
cost=49
elif book==3:
    cost=19
    b_total=float(cost*num)
print('Your book cost is $ ',format(b_total,'.2f'))
