Let's talk about Zed A. Shaw.
He's 74 inches tall.
He's 180 pounds heavy.
Actually that's not too heavy.
He's got Blue eyes and Brown hair.
His teeth are usually White depending on the coffee.
If I add 35, 74, and 180 I get 289.

3.Search online for all of the Python format characters.

# -*- coding: utf-8 -*-
print "%c is String&ASCII","%c"%'a'
print "%c is String&ASCII","%c"%'&'
print "%c is String&ASCII","%c"% 65
print "%c is String&ASCII","%c"% 254
#'%c'表示输出对应ASCII码

print '%s',"%s"%"abc"
print '%s',"%s"%"123"
print '%s:\t|{0:s}'.format('a')
print '%s:\t|{0}'.format('ass')
# '%s'表示字符串

print '%d','%d'%10
print '%d','%d'%-10
print '%d','%d'%-10.1
print '%d:\t|{0}'.format(123)
# '%d'表示有符号整数

print '%o','%o'%100
print '%o:\t|{0:o}'.format(13)
# '%o' 表示八进制

print '%x','%x'%1119
print '%02x:%02x:%02x:%02x:%02x:%02x'%(10,20,30,40,50,60)
print '%x:\t|{1:02x}:{0:012x}'.format(10,1)
#'%x'表示16进制

print '%X','%X'%1119
print '%02X:%02X:%02X:%02X:%02X:%02X'%(10,20,30,40,50,60)
print '%X:\t|{1:02X}:{0:012X}'.format(10,1)
#'%x'表示16进制大写

print '%f','%f'%18.1
print "%f:\t|{0:f}".format(4)
print '%f','%-33.5fjj'%18.1
print "%f:\t|{0:5.2f}jj".format(4)
#'%f表示浮点数，%m.nf',m表示位宽，n表示小数点后保留多少位，-表示对齐

print '%e','%e'%18.1
print "%e:\t|{0:e}".format(4)
print '%e','%-33.5ejj'%18.1
print "%e:\t|{0:25.2e}jj".format(4)
#'%e 表示科学计数法

print '%g','%g'%1000008.1
print "%g:\t|{0:g}".format(4)
print '%g','%-33.5gjj'%18.1
print "%g:\t|{0:25.2g}jj".format(4)
#'%g 根据值大小来使用%e或者%f
