-> Functions:
functions in python are first class citizen,
i.e. they can be passed around as variables.
for ex:
def hello():
print('hello')
greet = hello
del hello
print(greet())
Here in this example, the hello function is defined
and assigned to newly defined variable called greet.
Then the function name hello is deleted using del
keyword.
Here, the "del hello" is called, only the name of the
function i.e. hello is deleted instead of deleting
the function. This is due to the "greet" variable
which is still pointing the function location.
Hence, calling the function using greet function
name works but calling the function with hello
name will throw error as the hello variable is
deleted.
-> High Order function:
function which might return a function or take a function
as an argument.
for ex:
def greet(func):
func()
def greet2():
def func():
return 5
return func
-> decorators:
These are used to super boost our function:
for ex:
#decorator
def my_decorator(func):
def wrap_func():
print('************')
func()
print('************')
return wrap_func
@my_decorator
def hello():
print('hellllooooooooooo')
def bye():
print('see ya letter')
Here, if we our function powerful by using decorators.
if we use @<decorator-name> and define the function,
during the function call the decorator function will
take our function as an argument and inside the
decorator function it will call the passed function
inside wrapped function.
For using decorators we need to write the decorator
function in way as written above.
But, how it works under the hood?
This function defination with decorator is same as
@my_decorator
def hello():
print('helloooo')
var = my_decorator(hello)
var()
-> decorator with function having arguments:
for ex:
def my_decorator(func):
def wrap_func(*args, **kwargs):
func(*args, **kwargs)
return wrap_func
@my_decorator
def hello(greeting, emoji = ':('):
print(greeting, emoji)
hello('hii')
