本文实例讲述了Python可变参数函数用法。分享给大家供大家参考。具体如下:

#!/usr/bin/python
def f1(a,b): print a,b
def f2(a,*b): print a,b
def f3(a,**b): print a,b
def f4(a,*b,**c): print a,b,c
def f5(a,b=2,c=3): print a,b,c
def f6(a,b=2,*c): print a,b,c
f1(1,2)
f1(b=2,a=1)
f2(1,2,3,4)
f3(1,x=2,y=3,z=4)
f4(1,x=2,y=3)
f5(1)
f5(1,4)
f6(1)
f6(1,3,4,5,4)

#!/usr/bin/python
def echoo(*args,**kwargs):
  print args,kwargs
echoo(1,2,a=3,b=4)
pargs = (1,2)
pkwargs = {'a':3,'b':4}
apply(echoo,pargs,pkwargs)

希望本文所述对大家的Python程序设计有所帮助。
