Write a Python function that takes in three parameters - an adjacency matrix of a simple directed graph, a start node, and an end node; and returns "True" if there is a way to get from the start node to the end node using the provided edges. You can use this file as a starter code: path.py For example: Using the same graph given above. Consider your function with the same adjacency matrix given above as input and: If the start node is 1 and the end node is 4 then your function should return True. If the start node is 2 and the end node is 4 then your function should return False. Input: This function will have three parameters. First is an adjacency matrix in the form of a list of lists (as given above). Then the start_node and the end_node will be integers. Note that python indexing starts from 0 and not from 1, so the naming of the nodes will also follow the python convention and start from 0 instead of 1. Output: Boolean value: True or False.

Using the function provided, write a function that decides whether two lists are "identical". That is, if cycling by any number N makes the lists identical, the function should return True, otherwise, it should return False. for example identical([1,2,3,4,5], [5,4,1,2,3,]) should give True and identical([1,2,3,4,5,6], [1,2,3,5,4]) should give False.
Consider there is a list i.e. listA = {20, 10, 5, 15, 3} Write python code that: a. Creates a function updateListA(), which takes listA as input parameter, adds 30 after 20, and adds 40 at the end of the listA. [Hint: create a parameterized function] b. Creates a function newList(), which takes listA as input parameter and creates a new list newList with same elements as listA but in reverse order. c. If there is a function defined as below: def example(par1, par2=30): print(‘valid’) From the following function calls: i. example(par1=1) ii. example(1, 2) iii. example(par2=1) iv. example(par1=5, par2=6) Which call is valid? Write the values of par1 and par2 if a call is valid? Suggest corrections if a call is invalid.

Write a function that returns True if two arrays, when combined, form a consecutive sequence. A consecutive sequence is a sequence without any gaps in the integers, e.g. 1, 2, 3, 4, 5 is a consecutive sequence, but 1, 2, 4, 5 is not. Examples consecutive_combo([7, consecutive_combo([1, consecutive_combo([1, consecutive_combo([44, 46], [45]) → True 4, 5, 1], [2, 3, 6]) → True 4, 6, 5], [2, 7, 8, 9]) → False 4, 5, 6], [2, 3, 7, 8, 10]) → Fal Notes The input lists will have unique values. • The input lists can be in any order.
Define a function shuffle that takes a sequence with an even number of elements (cards) and creates a new list that interleaves the elements of the first half with the elements of the second half. Let's better understand what it means to shuffle a list in this way. Let's say there is some list [1, 2, 3, 4, 5, 6, 7, 8]. To interleave the first half [1, 2, 3, 4] with the second half [5, 6, 7, 8] means that your final list should contain the first element from the first half, then the first element from the second half, then the second element of the first half, then the second element of the second half and so on. So the interleaved version of [1, 2, 3, 4, 5, 6, 7, 8] would be [1, 5, 2, 6, 3, 7, 4, 8]. def card (n): """Return the playing card numeral as a string for a positive n 0 and n >> shuffle (range(6)) [0, 3, 1, 4, 2, 5] >>> suits = ['H', 'D', 'S', 'C'] >>> cards = [card (n) + suit for n in range (1,14) for suit in suits] >>> cards [:12] ['AH', 'AD', 'AS', 'AC', '2H', '2D', '25',…

Please write a function PythQuad(n) in python that generates a list of pythagorean quadruples (x,y,z,w) such that x <= y <= z <= w < n. Please do not use a triply nested loop, use the properties of a pythagorean quadruple to write the function.

I am very confused on how to answer this and any thing will help. Create a function that accepts a single list. Inside the function, have nested for loops (a for loop inside a for loop). The outer for loop iterates through every item in the list. The inner loop iterates through every subitem in item, and prints it. Test the function by passing it the list [ [0, 1, 2], [3, 4, 5], [6, 7, 8] ].
