   This sample program will introduce you to formatted strings using
   Python's "interpolation" operator.  See
   http://docs.python.org/library/stdtypes.html#string-formatting-operations
   for more details.

# Recall this code from way back in strings0.py?  There is a problem
# with this code--it puts a space between your name and the period.

userName = raw_input('What is your name? ')
print 'Hi', userName, '.  It is a pleasure to meet you.'
print


# Let's fix that problem.  The print statement below uses the
# "interpolation operator" (the percent sign) to insert one
# string (the user's name, stored in the variable userName) into
# the longer string 'Hi...'.
#
# -- Where does the interpolated string userName get inserted
#      into the larger string?
# -- What do you think the s in %s stands for?

userName = raw_input('What is your name? ')
print 'Hi %s. It is a pleasure to meet you.' % userName
print


# You can interpolate more than one thing, and more than one kind
# of thing, into a string.
#
# -- Note that you need parentheses and a comma to interpolate
#     more than one object into a string.
# -- What do you think the d in %d stands for?

userName = raw_input('What is your name? ')
numberString = raw_input('What is your favorite number? ')
number = int(numberString)
print 'Hi %s. Astonishingly, %d is my favorite number, too!' % (userName, number)
print

# You can make pretty columns with some special features of
# formatted strings.
#
# Try the following code.  Then look here:
#
#   http://docs.python.org/library/stdtypes.html#string-formatting-operations
#
# or here:

#
# to see if you can figure out a way to force the hourly wages to be
# right-justified with exactly two digits beyond the decimal point.

people = ['Alice', 'Bob', 'Chrysanthemum', 'Donald']
hourlyWages = [15.456, 6.8, 254.25, 20]

for k in range(len(people)):
    print '%-15s%f' % (people[k], hourlyWages[k])
