笨办法学Python ex06

字符串和文本

---

• 输入：

# -- coding: utf-8 --

x = "There are %d types of people." % 10 # 因为要引用数字，所以采用的%d
binary = "binary"
do_not = "don't"
y = "Those who know %s and those who %s." % (binary, do_not)
# 引用字符串，采用%s，如果用%r,上面就不能有引号，因为%r会全部引用

print x
print y

print "I said: %r." % x
# x是字符串，而本句是需要引用带引号的字符串，所以用%r来讲x全部引用，用%s的话，就引用不了引号了
print "I also said: '%s'." % y
# 与上句相反，这句已经有引号了，所以就用%s

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 # and关系，合并
