#assign a String to the variable x. The String is a formatted String 
#where we replace %d with 10
x = "There are %d types of people." % 10

#assign the variable 'binary' with a value which is a String 'binary'
binary = "binary"

#
do_not = "don't"
y = "Those who know %s and those who %s." % (binary, do_not)

print x
print y

print "I said: %r" % x
print "I also said: '%s'." % y

hilarious = False
joke_evaluation = "Isn't that joke so funny?! %r"

print joke_evaluation % hilarious

w = "This is the left side of..."
e = "a string with a right side."

print w + e
