问你是否是这样一个变量啊

caesar = "Graham"
praline = "John"
viking = "Teresa"

print caesar
print praline
print viking

变成小写

parrot = "Norwegian Blue"

print parrot.lower()

ministry = "The Ministry of Silly Walks"

print len(ministry)
print ministry.upper()

格式化

name = "Mike"
print "Hello %s" % (name)

name = raw_input("What is your name? ")
quest = raw_input("What is your quest? ")
color = raw_input("What is your favorite color? ")

print "Ah, so your name is %s, your quest is %s, "
"and your favorite color is %s." % (name, quest, color)

可以用%s来替换一段字符串

name = 'Crossin'

print '%s is a good teacher.' % name

输出

Crossin is a good teacher.

或者

print 'Today is %s.' % 'Friday'

输出

Today is Friday.
