What does this does?

Question

imagine I have a function.
def h():
print("HI")

But what does this mean h( people but a value here) why?
like h(hello) h(123)
how does it work?
i dont get it

Answer 1

Those are arguments that you pass to a function

def h(a):
print(a)

h("hello")

here a is parameter ,it can be any name

Answer 2

For Example:

def func(arg):
print(arg * 3)

Here arg is called an argument. An argument is what is passed to a function. Suppose you want a function to add two numbers. Then you would have to give or pass the two numbers the function needs to add them. What temporarily stores the given is called an argument variable.

If we call func(arg) to multiply something 3 times here:

Func(3):
3 * 3

It will be something like this. The name of argument variable doesn't matter nor does the variable you pass relate to it.

@Abhay
Can you give me a simple example please?
It would be very helpful

Answer 4

Here h is just a name given to a function.
So that you can execute the codes inside that function by calling its name

def h():
print("hi")
#calling h
h()

after h you will see () inside these brackets you can pass arguments to that function. Argument can be of any type like string,int,float,double,boolean etc..
def h(value):
print("hello" ,value)
val=input("enter name")
h(val)

Now this code will output hello followed by whatever you typed in the input.
You can pass multiple arguments by seperating it with comma

def h(value1,value2):
print(value1)
print(value2)
val1="hello"
val2="world"
h(val1,val2)

Answer 5

@ Shobhith J B
why did you first type
h(value1,value2)
print(value1)
print(value2)

then
call h(val1,val2)??

Answer 6

'''Simply, the value is some data you give the function that it uses
'''
#Like
def greet(name):
print("Whatsup ", name)

greet("Samy")
'''the function will use Sammy to do something. in this case print it to screen with some other sext '''

def subtract(a, b):
print(a - b)

subtract(10, 1)

About the name it is not neccessary that the name of arguments ie def h(value1,value2):
And parameters passed while caling ie h(val1,val2). The name can be any variable name, thay can be different in both.....

And about order if you want to call any function it should be already written...so i wrote function first then called that function.
