Slicing can be done on strings, arrays, lists, and tuples. numbers = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10] print(numbers[1 : : 2]) #output : [2, 4, 6, 8, 10]5. What is docstring in Python? Documentation string or docstring is a multiline string used to document a spec...
However, it should be noted that alloca is not portable and difficult to implement on machines without traditional stacks. alloca should not be used in programs that must be widely ported. C99 supports variable-length arrays (VLAs) and can be used instead of alloca....

How would you install Python on Windows and set the path variable? What do you know about the difference between deep and shallow copy? What are the benefits of using NumPy arrays over nested Python lists? What are the built-in types of Python?
Python also has built-in functions, such asglobals()andlocals(), that allow you to access variables in the global and local scopes, respectively. These functions can be useful for debugging or for working with more complex programs. 4. What are lists and tuples? What is the key difference...
