The code is :
class Ostream:
def lshift(self, other):
print(other, end=’ ')
return self
cout=Ostream( )
now input is cout<< “Hello” << “World”
In video it is explained that as return is self(return self) in the code so first of all cout<<“Hello” is executed and then cout<<“World” is left, which is further executed.
I didn’t understood it at all, please explain the concept.
hey @lucky.05 ,
class Ostream:
def __lshift__(self, other):
print(other, end=' ')
return self
cout=Ostream( )
cout << "Hello" << "world"
for first case ,
when we execute cout << “hello” , the lshift function detects variable other value as to be “Hello” ,
then it gets printed and return self ,means it returned hat class object itself , means actually the object which was just cout is now re intialized after printing “hello”.
so it becomes as cout << "world" in the compiler while hello in already printed in output.
Then the same thing happens again and you see a final output as Hello World.
I hope this would have helped you understand it properly.
