What is

*args and **kwargs

in Python?

Nitya Cloudtech

Let’s say you create a

function that excepts

arguments and adds them

def sums(a,b):

print(a+b)

sums(1,2)

Output:

To handle such situations

we use *args

def sums(*args):

x=sum(args)

print(x)

sums(1,2,4,5,8,11,123)

Output:

*args: Variable-Length

Positional Arguments

Usage: Allows a function to accept an arbitrary number of positional arguments. How it works: All additional positional arguments are collected into a tuple. (1,2,4,5,8,11,123)

and We want to add 2 more keys like Age, Salary for that we have to add 2 more paraments and for 10 fields ->10 Parameters and assign the values def record(x,i,y,j,z,): d={} d[x]=i d[y]=j

---

---

print(d)

Output:

{'Name': 'Aditya',

'Exp': '11 Years',

To handle such situation we

use **Kwargs

def record(**kwargs): print(kwargs) record(Name="Aditya",Exp="11 Years",Age=30,Salary=98000)

Output:

{'Name': 'Aditya', 'Exp': '11 Years', 'Age': 30, 'Salary': 98000}

def func(fargs,args,kwargs):* def func(fargs,args,*kwargs): print(fargs,args,kwargs) func('1st',' Second', 'Third', Fourth=4, Fifth=5) Output: 1st ('Second', 'Third') {'Fourth': 4, 'Fifth': 5}
