python3检查字典传入函数键是否齐全的实例

#Check if the incoming dictionary parameters are complete
def check_keys(list, dic):
  if all(k in dic for k in list):
    return 1
  else:
    return 0


def fun(**kwargs):
  if check_keys(['a', 'b', 'c'], kwargs):
    a = kwargs['a']
    b = kwargs['b']
    c = kwargs['c']

def printHello(user,age,address):
  print(user)
  print(age)
  print(address)
 
printHello(*('wang yuan wai',30,'Beijing'))

  print(data)
 
printHello(*('wang yuan wai',30,'Beijing'))

def printHello(name,age,address):
  print(name)
  print(age)
  print(address)
 
printHello(**{'name':'wp','age':30,'address':'Beijing'}) #调用函数时为解封，看原函数能否接受
printHello(name='wp',age=30,address='Beijing') #解封后的原型

printHello(**{'name':'wp','age':30,'address':'Beijing'})
