''' Purpose: demonstrate the printing of a string of characters
'''

# get a string of three letters
reply = input( "Enter a three letter-string: " )

### print the characters
first_character = reply[0]
second_character = reply[1]
third_character = reply[2]

print( first_character )
print( second_character )
print( third_character )

# If you have reply as 'abc' and do reply[0] + reply[1] + reply[2]
# that will concatenate the three strings so you'll
# have abc printed not
# a
# b
# c

# get a string 
reply = input( "Enter a string: " )

### print the characters
for c in reply:
    print( c )
    print('How is Cam doing today?')

# IMPORTANT: the loop variable changes value each iteration
# in the loop.
# If reply is 'computer'
# the first time, c is 'c' then next time it's 'o' then next time
# it's 'm' etc. all the way until we reach the end of a string.

# for loops
    # Everything indented into the for loop (loop body)
    # it will repeat those statements each iteration of the loop
    # aka each time we have a new loop variable value!
print('All done! :D')

result = '' # empty string
for c in reply:
    result = c + result
    print(result)

# soooo we see how we start off with an empty string
# and build up the value of result by adding the new
# character to the front of the current value of result each time

# Again, the loop value changes value each time to the next thing
# in your sequence.
# If you are running your loop like for c in string:
    # the loop variable will assume the value of each smaller
    # part of that string (it will be each character one at a time)
