use of kwargs and args in python classes

def myFun(*args,**kwargs): 
    print("args: ", args) 
    print("kwargs: ", kwargs) 
    
myFun('my','name','is Maheep',firstname="Maheep",lastname="Chaudhary")

# *args - take the any number of argument as values from the user 
# **kwargs - take any number of arguments as key as keywords with 
# value associated with them

Kwargs in python

def tester(**kwargs):
   for key, value in kwargs.items():
       print(key, value, end = " ")
tester(Sunday = 1, Monday = 2, Tuesday = 3, Wednesday = 4)

what are args and kwargs in python

# Python program to illustrate   
# **kwargs for variable number of keyword arguments 
  
def info(**kwargs):  
    for key, value in kwargs.items(): 
        print ("%s == %s" %(key, value)) 
  
# Driver code 
info(first ='This', mid ='is', last='Me')     

python *args and **kwargs

def foo(*args):
    for a in args:
        print(a)        

foo(1)
# 1

foo(1,2,3)
# 1
# 2
# 3

kwargs in python

def display(**kwargs):
    d = {k.upper():v.upper() for k,v in kwargs.items() }
    return d
   
d = {"name":"neo","age":"33","city":"tokyo"}
print(display(**d))

*kwargs

# Python program to illustrate 
# *kwargs for variable number of keyword arguments
 
def myFun(**kwargs):
    for key, value in kwargs.items():
        print ("%s == %s" %(key, value))
 
# Driver code
myFun(first ='Geeks', mid ='for', last='Geeks') 

''' output: 
last == Geeks
mid == for
first == Geeks
'''

**kwargs python

def calculate(n, **kwargs):
	n += kwargs["add"]
	n *= kwargs["multiply"]
	return n

print(calculate(3, add=3, multiply=5)) # (3+3)*5 = 30

kwargs in python

def display2(a,b,c):
    print("kwarg1:", a)
    print("kwarg2:", b)
    print("kwarg3:", c)

d = {"a": 1, "b": 2, "c": 3}
display2(**d)

**kwargs,*args

def myFun(arg1, arg2, arg3):
    print("arg1:", arg1)
    print("arg2:", arg2)
    print("arg3:", arg3)
 
 
# Now we can use *args or **kwargs to
# pass arguments to this function :
args = ("Geeks", "for", "Geeks")
myFun(*args)
 
kwargs = {"arg1": "Geeks", "arg2": "for", "arg3": "Geeks"}
myFun(**kwargs)

**kwargs

*args and **kwargs in Python are used in  a function that doesn't have
a specified number of arguments (parameters).

**kwargs in Python

def myFun(arg1, **kwargs):
    for key, value in kwargs.items():
        print("%s == %s" % (key, value))
 
 
# Driver code
myFun("Hi", first='Geeks', mid='for', last='Geeks')
