实验目的:

  • Python运行环境的安装
  • 交互式运行Python
  • Python编辑器安装
  • 编辑、运行Python程序

实验内容:

>>> 1+1
>>> 2**10
>>> r = 5
>>> pi = 3.14159
>>> pi*r*r
>>>
>>> "hello world"
>>> print "hello world"
>>> "hello " + "world\n"
>>> print "hello " + "world\n"
>>> 
>>> x = 54
>>> y = 36
>>> if x>y:
        print x
    else:
        print y
>>>
>>> while y != 0:
        y, x = x%y, y
>>> print x
>>>
>>> import sys
>>> sys.version
>>> sys.platform
>>> 
>>> help()
>>> help(sys)
>>> dir(sys)
>>> (Ctrl+d或者ctrl+z)
  • 下载安装一种Python编辑器,并熟悉它的使用。(比如SPE - Stani's Python Editor, IDLE, DrPython, Eclipse+PyDev, Boa Constructor,Emacs, VIM等)

  • 运行编辑器,编辑一段Python代码,并运行它。比如

   1 def GCD(x,y):
   2     while y != 0:
   3         y, x = x%y, y
   4     return x
   5 
   6 print GCD(36, 54)

或者

   1 def buildConnectionString(params):
   2     """Build a connection string from a dictionary of parameters.
   3 
   4     Returns string."""
   5     return ";".join(["%s=%s" % (k, v) for k, v in params.items()])
   6 
   7 if __name__ == "__main__":
   8     myParams = {"server":"mpilgrim", \
   9                 "database":"master", \
  10                 "uid":"sa", \
  11                 "pwd":"secret" \
  12                 }
  13     print buildConnectionString(myParams)
