Python3.2 --- Print函数用法

1. 输出字符串

>>> strHello = 'Hello World' 

>>> print (strHello)

Hello World

2. 格式化输出整数

支持参数格式化，与C语言的printf类似

>>> strHello = "the length of (%s) is %d" %('Hello World',len('Hello World'))

>>> print (strHello)
the length of (Hello World) is 11

3. 格式化输出16进制，十进制，八进制整数

#%x --- hex 十六进制
#%d --- dec 十进制
#%o --- oct 八进制
 
>>> nHex = 0xFF
>>> print("nHex = %x,nDec = %d,nOct = %o" %(nHex,nHex,nHex))
nHex = ff,nDec = 255,nOct = 377
