so im trying to make it so that pressing enter without inputting any value, will break the loop, however, an empty string can be used because of
for i in range(len(x_str_array)): x[i] = int(x_str_array[i]) bit.
'Exercise 7.3' # modified program from exercise 7.2 a=1 z="" while x !=z: x_str = raw_input('Enter Start,Stop,Increment: ') if x==z: break else: x_str_array = x_str.split(',') # splits the string where a comma pops up x = range(len(x_str_array)) # Preallocation step- makes x= the same length as x_str_array for i in range(len(x_str_array)): x[i] = int(x_str_array[i]) a=x b=x c=x for number in range(a,b,c): print "number:", number, " square:", number**2, " cube:", number**3
please advise me on this.
p.s yes i am a complete novice
i thought maybe using an empty tuple or list or something, but that wouldn't work either.
