''' Purpose: print out 128 lines of the string 'again and again'
'''

# print out 'again and again' 128 times

# for loops have this syntax
# any lines of code here are outside the loop
# for iterator in sequence:
    # do something
    # this whitespace helps us separate out what needs to be done under the loop vs. outside the loop
# any lines of code here are outside the loop

# the iterator (which here is called i) is a placeholder
# in helps us see where i comes from; i should come from some kind of sequence
# range() is typically the kind of sequence we'll use when we do for loops, but it doesn't have to be a range

# for anything in range(0, 128): # we want to print 128 times...we could also say range(1, 129) to repeat an action 128 times
#     print('again and again')
    # notice how this line is indented
    # the indented lines are what is repeated

# for i in range(0, 0): # how many times will this print? 0? 1? error? - doesn't do anything
#     print('again and again')
    # for loops do not actually have to do anything

a = input('Enter a number: ')
b = input('Enter a number: ')
c = input('Enter a number: ')
print()

a, b, c = int(a), int(b), int(c)
for j in range(a, b):
    print(j)
print('j is now', j)  # this only shows the last value of j because this line works outside the loop
print()

for k in range(a, b, c):  # just like with randrange(), range() can do increments...so range(a, b, c) works with values from a to b-1 in increments of c
    print(k)
print('k is now', k)
#     print(j)
# print('j is now', j)
print()

for k in range(b, a, -c):  # how to do a range backwards
