Slicing refers to creating a subset of an existing string like cutting out a portion of the sequence. Indexing refers to accessing individual elements using its index value in a sequential manner. Here is the syntax: variable_name[ start : stop : step_value ] Here is the syntax: variable_...

Use the filter Function to Get a Subarray of an Array in PythonThe filter function can be employed to create a subarray based on a specified condition. It takes a function and an iterable as arguments.Example:original_array = [1, 2, 3, 4, 5] subarray = list(filter(lambda x: x % ...
Use a list comprehension to remove elements from a list based on a condition, e.g. `new_list = [item for item in my_list if item > 100]`.
of the file import asyncio # note that normally you use gather() function to run several functions # concurrently but we actually modify the data and we rely on the order of functions for func in [ create, read, update, delete, joins, filter_and_sort, subset_of_columns, pagination, ...
In this part of the assignment, you will create a snake agent to learn how to get food as many as possible without dying. Inorder to do this, you must use Q-learning. Implement the TD Q-learning algorithm and train it on the MDP outlined above.Q(s, a) Q(s, a) + (R(s) + ...
