Introduction to Python ternary operations and Python functions

Ternary operation:

if 1+1 == 2 :
    print (True)
else:
    print (False) 
     
#等同于：
print (True if 1+1==2 else False)

Basic syntax of function def XX():

    定义函数
#  return aa  返回值
# 或 pass      什么也不返回
# XX()   调用函数
 
#函数的有三中不同的参数：
 
#------普通参数------
def func(name):  
    print (name)
 
func('fanhaibo')   
 
# ------默认参数------
 
def  func2(name,age=30):
    print (name,age)
 
func2('fanhaibo')
func2('张三',20)
 
# ------动态参数------
# *args
def func3(*args):
    print  (args)
 
func3(1)
func3('hello')
func3(1,2,3)
func3([1,2,3])
func3({1:'a',2:'b'})
#**kwargs:可以传入多个元素以key= value
def func4(**kwargs):
    print(kwargs)
 
func4(name='fanhaibo',age=30)  
 
#*args **kwargs
 
def func5(arg,*args,**kwargs):
    #print  (args)
    #print(kwargs)
    print  (arg,args,kwargs)
 
#把1传给arg，把’a‘’b‘’c‘作为元组传给args，把name、age传给kwargs
func5(1,'a','b','c',name='fanhaibo',age=30)
