What are args and kwargs in python

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 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))

Args in python

# if args is not passed it return message
# "Hey you didn't pass the arguements"

def ech(nums,*args):
    if args:
        return [i ** nums for i in args]  # list comprehension
    else:
        return "Hey you didn't pass args"
    
print(ech(3,4,3,2,1))

Args in python

# normal parameters with *args

def mul(a,b,*args): # a,b are normal paremeters
    multiply = 1
    for i in args:
        multiply *= i
        
    return multiply

print(mul(3,5,6,7,8))   # 3 and 5 are being passed as a argument but 6,7,8 are args

Args in python

def mul(*args):  # args as argument
    multiply = 1
    for i in args:
        multiply *= i
        
    return multiply

lst = [4,4,4,4]
tpl = (4,4,4,4)    

print(mul(*lst))  # list unpacking
print(mul(*tpl)) # tuple unpacking

Args in python

def wrap(*args):
        lis = list(args)  # it is important to convert args into list before looping, args take tuple as a argument 
        for i in range(len(lis)):
            lis[i] = lis[i] * 2
        args = tuple(lis)
        return args
print(wrap(2,3,4,5,6))
