Types of arguments in python

1. Default arguments

2. Keyword arguments

3. Positional arguments

4. Arbitrary positional arguments

5. Arbitrary keyword arguments

Default arguments :

Default arguments are values that are

provided while defining functions.The

assignment operator = is used to assign a default value to the argument.

Ex:

def add(a,b=5,c=10):

 return (a+b+c)

x=add(14)

print(x)

Keyword Arguments :

Functions can also be called using keyword arguments of the form

kwarg=value.During a function call, values passed through arguments don’t need to be in the order of parameters in the function definitions.

Ex :

def add(a,b,c):

return (a+b+c)

m=add(b=10,c=15,a=20)

print(m)

Positional Arguments :

arguments are passed in order one after the other, those arguments are called the "Positional arguments."

Eg :

def add(a,b,c):

 return (a+b+c)

print (add(10,20,30))

Arbitrary Positional Argument :

For arbitrary positional argument, an asterisk (*) is placed before a parameter in function definition which can hold non-

keyword variable-length arguments. These arguments will be wrapped up in a tuple

Ex :

def add(*b):

 result=0

for i in b:

 result=result+i

 return result

t1=add(1,2,3,4,5)

print(t1)

t2=add(10,20)

print(t2)

Arbitrary Keyword Arguments :

For arbitrary keyword argument, a double asterisk (**) is placed before a parameter in a function which can hold keyword variable-length arguments.

Ex :

def fn(**a):

 for i in a.items():

 print (i)

fn(numbers=5,colors="blue",fruits="apple")
