In Python, empty brackets represent an empty list. A list is a collection of items, and you can create an empty list by using the brackets without any items inside. Here's an example: my_list = # Create an empty listprint(my_list) # Output: my_list.append(10) # Add an item to the listprint(my_list)...

In Python, empty brackets [] represent an empty list. A list is a collection of items, and you can create an empty list by using the brackets [] without any items inside. Here's an example: my_list = [] # Create an empty listprint(my_list) # Output: []my_list.append(10) # Add an item to the listprint(my_list) # Output: [10] In this example, my_list is an empty list initially, created using the empty brackets []. We then add an item to the list using the append() method, which modifies the list in place by adding the item to the end of the list. The print() function is used to display the contents of the list, which in this case is [10]. Empty brackets can also be used to represent an empty dictionary {}, an empty set set(), and an empty tuple (), depending on the context in which they are used. read less

In Python, empty brackets [] represent an empty list. A list is a collection of values that can be of any data type, such as numbers, strings, or other objects. An empty list is a list with no elements. It can be created by simply assigning [] to a variable. For example: You can also create an empty list using the list() constructor: Once you have an empty list, you can add elements to it using the append() method or by concatenating it with another list. Empty brackets can also be used to access elements of a list by their index. For example, my_list[0] would access the first element of the list (assuming it exists). If the list is empty, trying to access an index will result in an IndexError being raised. Note that empty brackets have other meanings in Python as well. For example, when used with a dictionary, empty brackets {} represent an empty dictionary. When used with a set, empty brackets set() represent an empty set. read less

Empty brackets "" are used to denote an empty list. A list is a mutable collection of items enclosed in square brackets, and it can contain elements of any data type. When the brackets are empty, it means that the list contains no elements and is considered empty.

Is it possible to learn C++ and Python at the same time?
No, Always learn and master one programming language and then Choose other. If you learn two different languages same time your written programme will fail due to the incomplete knowledge of programming. I suggest you to learn python first then c++.
