# Printing a string with the index numbers beneath it

# Matt Bishop, ECS 10, Spring 2014

#
# Read in a string
#
s = input("Enter string: ")

#
# Count the number of characters
# the number of digits in the number of characters is how
# wide to make each slot
#
digits = len(str(len(s)))

#
# Print a blank line for style
#
print('')

#
# This looks ugly but it's really easy
# Suppose there are 123 characters in the input
# we then want a slot of len("123")+1 or 4 spaces
# this constructs a format string of %4d
# the first "%%" is "%", then comes "%d" (digits,
# see above), then the following "d"
#
fmt = "%%%dd |" % digits
    
#
# print index values; note we use the above format string
#
for pos in range(len(s)):
    print(fmt % pos, end='')

#
# End the line
#
print('')

#
# Now we do what we did before, but to make space
# for printing a character; note the width is the
# same as for the index list, above (see final "s"
# in the format string)
#
fmt = "%%%ds |" % digits
    
#
# Now print the character at each index
#
for ch in s:
    print(fmt % ch, end='')
print()
