Python3.2中Print函数用法实例详解

> strHello = 'Hello World' 
> print (strHello)
Hello World

> strHello = "the length of (%s) is %d" %('Hello World',len('Hello World'))
> print (strHello)
the length of (Hello World) is 11

> nHex = 0xFF
> print("nHex = %x,nDec = %d,nOct = %o" %(nHex,nHex,nHex))
nHex = ff,nDec = 255,nOct = 377

import math
> print('PI=%f'%math.pi)
PI=3.141593
> print ("PI = %10.3f" % math.pi)
PI =   3.142
> print ("PI = %-10.3f" % math.pi)
PI = 3.142   
> print ("PI = %06d" % int(math.pi))
PI = 000003

> precise = 3
> print ("%.3s " % ("python"))
pyt
> precise = 4
> print ("%.*s" % (4,"python"))
pyth
> print ("%10.3s " % ("python"))
    pyt

> lst = [1,2,3,4,'python']
> print (lst)
[1, 2, 3, 4, 'python']

> d = {1:'A',2:'B',3:'C',4:'D'}
> print(d)
{1: 'A', 2: 'B', 3: 'C', 4: 'D'}

> for i in range(0,6):
  print (i,)
