Python常用的方法定义:方法在OOP中会经常用到,减少代码的冗余,作为一门面向对象的语言,Python自然也有自己的方法定义。那么怎样在Python中定义一个方法呢,很简洁的方法:define functionname()调用的时候直接使用这个方法名就可以了,functionname(),就可以了,当然在方法定义的时候一样可以定义它的输入参数,例如:define functionname(yourname,myname),在调用的时候传入参数即可。__author__="Alex"
__date__ ="$2011-2-17 10:39:27$"
if __name__ == "__main__":
print "Hello";
#define a function
def welcome():
print("Welcome to my python class")
# define a function by arg
def welcome_bylevel( name, level ):
print ( "Welcome " + name + " to the program =)" )
print ( "We will try some things out." )
if level == "pro": print ( "Be patient, I am beginner." )
print ("")
welcome()
welcome_bylevel( "Alex", "beginner" )
welcome_bylevel( "Viki", "pro" ) Console Output:Hello
Welcome to my python class
Welcome Alex to the program =)
We will try some things out.
Welcome Viki to the program =)
We will try some things out.
Be patient, I am beginner.动态调用在Python代码中方法的参数如果不确定为多少个的时候,可以用*arg来表示,例如:__author__="Alex"
__date__ ="$2011-2-17 10:39:27$"
if __name__ == "__main__":
print "Hello";
#define a function
def welcome(name,level="beginner",*skill):
print("Hello, "+name)
if level!="beginner":
print("We will show something out");
else:
print("I am beginner of python")
if len(skill)>0:
for i in skill:
print("you are good at:"+i)
welcome("Viki")
welcome("Alex","pro","Python","Linux")控制台输出:Hello
Hello, Viki
I am beginner of python
Hello, Alex
We will show something out
you are good at:Python
you are good at:Linux
