新手上路，請老司機多多指教。

文中練習：

x = "There are %d types of people." % 10
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

正文：

1、

# -- coding: utf-8 --
#這裡有10種類型的人
x = "There are %d types of people." % 10 
#命名
binary = "binary"
do_not = "don't"
#這些人知道bianry，而著一些人不知道bianry
y = "Those who know %s and those who %s."
 
 % (binary, do_not)

#列印x和y
print x
print y

#我說x這段話
print "I said: %r." % x
#還是我說y這段話
print "I also said: '%s'." % y

#定義這個變數為False（bool型（題外話，今天才知道51沒有bool型別））
hilarious = False
#一個joke
joke_evaluation = "Isn't that joke so funny?! %r"

#列印joke 這個用法還是蠻好玩的，居然可以這樣用
print joke_evaluation % hilarious

#就w一段話，e一段話
 

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

#兩段話合起來
print w + e

2、

y = "Those who know %s and those who %s." % (binary, do_not)

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

一個疑問，我回去檢查輸出的時候發現False是直接輸出False而不是我想的bool型輸出0。以上4處是字串內包含了字串。

3、

我只找到4處。

相當於print第一個後再print第二個吧。python這點真舒服，感覺就是按自然語言梳理的，很舒服。
