1.定义变量
a = 10
b = 2
c = a+b
print(c)
直接定义


----------


2.判断
score = 90
if score > 60:
    print("pass")
else:
    print("gameover")


----------


3.循环format
for i in range(0,100):
    print(i)

for i in range(0,100):
    print("Item{0},{1}".format(i,"HelloWorld"))


----------


4.定义函数
def sayHello():
    print("HelloWorld")
    print("Go")
    
def max(a,b):
    if a > b:
        return a
    else:
        return b

sayHello()
print(max(2,3))


----------


5.面向对象
class Hello():
    def __init__(self,name):
        self._name = name
    def sayHello(self):
        print("Hello {0}".format(self._name))

h = Hello("gg")
h.sayHello()


----------


6.引入python文件
loadlib.py
class Hello:
    def sayHello(self):
        print("Hello")
        
LearnPython.py
import loadlib
h = loadlib.Hello()
h.sayHello() 

from  loadlib import Hello
h = Hello()
h.sayHello()
