In this lecture, we are discussing types of arguments in python :
-- formal argument
-- actual argument

Actual arguments have 4 types:
1)position
2)keyword
3)default
4)variable length argument

Position argument:
-- During a function call, values passed through arguments should be in the order of parameters in the function definition. This is called positional arguments.
e.g
def person(name,age):
print(name)
print(age)
add(5,6)

keyword argument:
-- During a function call, values passed through arguments don’t need to be in the order of parameters in the function definition. Keyword arguments can achieve this.
-- All the keyword arguments should match the parameters in the function definition.
e.g
person(age=28,name='navin')

default argument:
-- Default arguments are values that are provided while defining functions.
-- The assignment operator = is used to assign a default value to the argument.
-- Default arguments become optional during the function calls.
-- If we provide a value to the default arguments during function calls, it overrides the default value.
-- The function can have any number of default arguments.
-- Default arguments should follow non-default arguments.

e.g
def person(name,age=28):
print(name)
print(age)
person('navin')

variable length argument:
-- if you want to pass multiple value in a function call we can use variable length argument
def sum(a,*b):
print(a)
print(b)
c=a
for i in b:
c=c+i
print(c)

sum(5,6,34,78)

[vijayragav]

This works for variable length arguments:
def add(x, *y):
c = x+sum(y)
print(c)
add(5, 6, 7, 8)

[MrCEO-jwvm]

you just removed a huge amount of pressure I was feeling when I saw my prof using default variables out of nowhere. I felt lost till now. Thanks!

[vvsrakesh]

7:30 wow you are making errors just to make the concept more clear, you are great sir.

[prathampandey]

never understood a single thing about functions from my school teacher in about 3 monthd but here in just one go i am crystal clear

[fireworks]

Note:All required parameters must be placed before any default arguments

[rehanbaig]

Sir you are great trainer, I have gone through previous 35 videos of this playlist. Kindly guide to beginners about practicing python on projects. As you said in one of your previous video that listening and seeing videos is very easy, I want some guidance about practicing python by beginners.

[tobiasrasmussen]

Thank you so very much for this. I got stuck on the concept of keyword arguments on another tutorial, and luckily I found your channel with this video. Turns out it's extremely simple once you get someone who can actually explain the stuff properly. Thank you!

[vakhariyajay]

Thank you very much. You are a genius.

[chiragukey]

in this you can pass 2 value or more and can try for user input
def sum (a, *b):
c=a
if len(b)<2:
print(a+b[0])

else:
for i in b:
c=c+i
print(c)


sum(5, 4, 5, 4, 6)

[sutirthabrahmachari]

Sir its a blessing to have a teacher like u on youtube thanks a ton

[nishpandya]

The way u r teaching sir is so simple and easy to grasp. Very thanks for this. ✌️

[nvishnusai]

We can also write like this sir
def sum (a, b=[6, 7, 8]):
c = a+ b[0]+b[1]+b[2]
print (c)
sum (a=5)

He is a real teacher as well as a coder...he could have just deleted the scenes where he got errors, but he kept them to show us that, what type of problems we can get.
