hello guys can s.one explain for me this code I didn't understand it ! thank u so much nd have a nice day 🤗

Question

def apply_twice(func,arg):
return func(func(arg))
def add_10(x):
return x_44
print (abs(apply_twice(add_10,_44)))
>>>132

Answer 1

The code should actually look like this:

def apply_twice(func,arg):
return func(func(arg))
def add_10(x):
return x+44
print (abs(apply_twice(add_10,44)))

What it does:

1. the apply_twice() returns the output of func being applied on arg and then being applied again on the result

2. the add_10() just adds 44 to the argument and returns the value

3. So what happens here is: apply_twice the function of add_10 on an argument of 44

4. So it goes:
add_10(add_10(44)) => add_10(44+44) => add_10(88) => (44+88) => 132

abs() just prints the absolute value which does not change anything for positive values.
