重新梳理Python基礎（1）

1. 指令碼中寫中文出現亂碼，用以下可以解決。參考http://www.python.org/dev/peps/pep-0263/

          # coding=<encoding name>          #!/usr/bin/python          # -*- coding: <encoding name> -*-          #!/usr/bin/python          # vim: set fileencoding=<encoding name> :

2. 輸出格式，先看代碼

my_name = 'Zed A. Shaw'print "Let's talk about %s." % my_nameprint "========================================================"print round(2.00034, 3) #2.0print round(345.2345, 2) #345.23print "hex of 1444 is %x" % 1444   #5a4

round(num, n)函數是對浮點數num對第n位小數四捨五入，n取正負均可。

round(345, -1) = 350.0

round(345, -3) = 0.0

round(345, 0) = 345.0
