A nice way to get the most out of these examples, in my opinion, is to read them in sequential order, and for every example:Carefully read the initial code for setting up the example. If you're an experienced Python programmer, you'll successfully anticipate what's going to happen next...
Node.js: It is used to handle the server-side. Now that we know about MEAN stack, let’s further see each of its components in detail. We will start with MongoDB, and then we will learn the different versions of it, why it is used in MEAN, and much more. What is MongoDB? Mong...

Tensor t is taken as an argument in flatten function and since reshape has to be done as the next part, -1 is passed as the second argument. The value should be based on the number of elements inside the tensor, and it equals the product of elements in the tensor. For example, if ...
Suppose you have two Python files: main_script.py and module_example.py. Contents of module_example.py: def say_hello(): print("Hello from module_example!") print("__name__ in module_example:", __name__) if __name__ == '__main__': print("This code is executed only when ...
simple print(Example[0:7:3]) --> you will get "Vie". String functions in Python? Find length of string using len(). "len" is nothing just short form of length.syntax to write len functionprint(len(name_of_string)) To check string endwiths given entry or not (it will return true...
Poor OOPS True OOPS Pure OOPS C++ is example of poor OOPS, actually in C++, we can access private data member outside the class using pointers and friend function. Java and C# are example of True oops. ADA and SMALLTALK are example of Pure oops. ...
