Python-基本语法

# coding=utf-8

print “Hello Python”

1-变量

a=12

b=23

c=a+b

print c

2-判断语句

score=67

if score>=90:

print “优秀”

elif score>=60:

print “及格”

else:

print “不及格”

3-循环语句

for i in range(0,10,2):

print (“Item {0} {1}”.format(i,”Fishyer”))

4-函数

def say():

print (“我在说话”)

def max(a,b):

if a>b:

return a

else:

return b

say()

print (max(12,23))

5-面向对象

class Person:

def init(self,name):

self.name=name;

def say(self,content):

print(“{0}说:{1}”.format(self.name,content))

class Student(Person):

def init(self,name,grade):

Person.init(self,name)

self.grade=grade

def say(self,content):

Person.say(self,content)

def study(self,course):

print (“{2}年纪的{0}在学习{1}”.format(self.name,course,self.grade))

laoWang=Person(“老王”)

laoWang.say(“我是逗比”)

xiaoMing=Student(“小明”,1)

xiaoMing.say(“我去找小红了”)

xiaoMing.study(“语文课”)

6-引用外部文件

import lib

b=lib.Book(“数学之美”)

print (“我借了一本书:{0}”.format(b.getName()))

from lib import Book

b=Book(“五子棋先手必胜法”)

print (“我买了一本书:{0}”.format(b.getName()))
