How this function is working in python?
https://sololearn.com/compiler-playground/cEUPyQhFa7gb/?ref=app In the last line, if we call print(L[2]). It is calling magic method __getitem__ and print stuffs. But I'm not sure how this magic method is working. Because the parameter the method has is something like getitem(self,index). So shouldn't we call it by : print(L,2) instead of print(L[2]) ? Because now it perfectly matches with magic method parameters..

maybe you mean
print(L.__getitem__(2))
it's operator overloading.
__add__ can be used as +,
__getitem__ can be used as [ ].

but you can also use the __xxx__ version

Bob_Li Yes right.
print(L.__getitem__(2)) does make sense!!
