Python之變量和打印

#coding:utf-8
name = 'Zed A. Shaw'
age = 8.123 # not a lie
height = 74 # inches
weight = 180 # lbs
eyes = 'Blue'
teeth = 'White'
hair = 'Brown'

print "His name is %s" %name
#這里可以將常量也以這種方式打印出來
#格式化字符數字寬度為10，不夠前面用0代替，精度為2
print "His age is %010.2f" %10

#r是不管是什么都打印出來   

print "His height is %r inches and weight is %d lbs" %(height,weight)

print "If I add %d,%d and %d is %d" %(age,height,weight,age+height+weight)

如下記錄一些學習過程中遇到的知識點:
1.字符串竟然也可以乘以數字，標示重復打印多少遍

print "mh" * 10  

mhmhmhmhmhmhmhmhmhmh

2.print語句默認的會在后面加上 換行  加了逗號之后 換行 就變成了 空格

print "hi",
print "my"
hi my
