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()))
