#c:\pyhone33
#File name: def.py
# 基本实现语句：
def printMax(a,b):
if a > b:
print(a), "is maximum"
else:
print(b), "is maximum"
printMax(3,4)
x = 5
y = 8
printMax(x,y)
#局限于语句块的赋值：
def func(x):
print("x is", x)
x = 2
print("changed local x to ", x)
x = 50
func(x)
#使用 golbal 命令使全局赋值：
def func1():
global x
print("x is", x)
x = 2
print("changed lcoal x to", x)
x = 50
func1()
print(x)
#给形参指定值：
def func2(a,b=20,c=30):
print("This a", a, "This b", b, "This c",c)
func2(10)
func2(100,200)
func2(c=300,a=1000)
