python 概览

 python是一个跨平台的脚本语言.需要运行在虚拟机上,有点类似于java.在windows系统下可以去python官网下载msi 安装包进行安装.其他系统类似.

下面是我编写的一个python入门级别的概要脚本:test.py

import time;#导入模块其实就是脚本文件名

print('hello every one.\n')

print('\t welcome to use python language.')

tup = ('米斯特.唐','male',1990)#这是一个元组


print(tup[0:3])

dict = {}# 这是一个字典

dict['狼王'] = 'Mr Yu'

print(dict['狼王'])

arr = ['高亮','米斯特.唐','爆炒螺丝','杜','木头棒子'] # 这是一个数组
print(arr)

str = 'good afternoon'

print('it is ' + str[4:])

now = time.time()

print(now)

print("program is very insteresting.")

def func(name):    #定义函数
    print('hello',name)
    pass
    print('上面的pass仅仅是个占位符,不执行')
    return;

func('高亮')

#######下面是面向对象
class Employee:
   '所有员工的基类'
   empCount = 0

   def __init__(self, name, salary):
      self.name = name
      self.salary = salary
      Employee.empCount += 1
   
   def displayCount(self):
     print ("Total Employee %d" , Employee.empCount)

   def displayEmployee(self):
      print ("Name : ", self.name,  ", Salary: ", self.salary)

#"创建 Employee 类的第一个对象"
emp1 = Employee("Zara", 2000)
#"创建 Employee 类的第二个对象"
emp2 = Employee("Manni", 5000)
emp1.displayEmployee()
emp2.displayEmployee()
print("Total Employee %d" , Employee.empCount)

命令行:python test.py.下图是运行结果:
