[Tutor] Lists/raw_input

[Michael Lewis]

I want to prompt the user only once to enter 5 numbers. I then want to
create a list out of those five numbers. How can I do that?

I know how to do it if I prompt the user 5 different times, but I only want
to prompt the user once.

Thanks.

Hi Michael,

I bet there is a better way (which I would like to see), but here is what I 
have come up with for my own uses.


ints = []
u_in = False
while u_in == False:
try:
u_input = raw_input('please enter 5 integers, space separated\n 
   ')
for n in u_input.split():
ints.append(int(n))
u_in = True
except:
print('input error, try again')


The while loop is set up in case your user inputs a float or string instead of 
just integers.  You can also imagine putting checks in case you want exactly 5 
integers, etc.


Cheers,

Andre

You can take your input from your user in one line seperated by 
something like a space and then split it after you capture it so for eg.


user_input = raw_input('enter 5 numbers seperated by a space each: ')
list_from_input = user_input.split() # Split by default splits on 
spaces, otherwise you need to specify the delimiter
# Then you can validate the list to ensure all 5 are actually numbers, 
otherwise prompt the user to re-enter them


Hope that help.
