先贴上章节所打的代码：
my_name = 'Zed A. shaw'
my_age = 35 # not a lie
my_height = 74 # inches
my_weight = 180 # lbs
my_eyes = 'Blue'
my_teeth = 'White'
my_hair = 'Brown'
print "Let's talk about %s." % my_name
print "He's %d inches tall." % my_height
print "He's %d pounds heavy." % my_weight
print "Actually that's not too heavy."
print "He's got %s eyes and %s hair."%(my_eyes,my_hair)
print "His teeth are usually %s depending on the coffee." % my_teeth
print "If I add %d,%d,and%d I get %d."%(my_age,my_height,my_weight,my_age+my_height+my_weight)
正文：
1、我用的是PyCharm，所以我用了replace
name = 'Zed A. shaw'
age = 35 # not a lie
height = 74 # inches
weight = 180 # lbs
eyes = 'Blue'
teeth = 'White'
hair = 'Brown'
print "Let's talk about %s." % name
print "He's %d inches tall." % height
print "He's %d pounds heavy." % weight
print "Actually that's not too heavy."
print "He's got %s eyes and %s hair."%( eyes, hair)
print "His teeth are usually %s depending on the coffee." % teeth
print "If I add %d,%d,and%d I get %d."%( age, height, weight, age+ height+ weight)
2、这里先说明下%s 是string类型，%d是digital，这是我的理解，如有错误，欢迎批评指正！
print "Print string and digital:%r,%r" % (name,age)
%s 字符串（采用str()的显示）
%r 字符串（采用repr()的显示）
%c 单个字符
%b 二进制整数
%d 十进制整数
%i 十进制整数
%o 八进制整数
%x 十六进制整数
%e 指数（基底写为e）
%E 指数（基地写为E）
%f 浮点数
%F 同上
%g 指数(e)或者浮点数（根据显示长度）
%G 指数(E)或者浮点数（根据显示长度）
%% 字符“%”
4、
height = 74 # inches
weight = 180 # lbs
cm = 0.254
kg = 0.454
height_cm = cm*height
weight_kg = kg*weight
print "He's %r inches tall." % height_cm
print "He's %r pounds heavy." % weight_kg
这里在写的过程中，直接在print后相乘赋值，出现 TypeError: can't multiply sequence by non-int of type 'float 的报错，看字面意思是不支持float的类型。我想应该是python不支持 print内出现类型转换吧（猜测），于是就有了上面的代码，现在外部转换后再进行print。
