Matrix Multiplication by a Scalar Please write a function calculate (matrix, scalar) that takes two arguments: a nested list that represents a matrix and an integer that represents a scalar. The function returns a nested list that corresponds to the result of matrix multiplication by a scalar. Your function should work with the following code: if __name__ == '__main__': scalar 3 A [[1,0,0], [0,1,0], [0,0,1]] D= calculate (A, scalar) assert D= [[3,0,0], [0,3,0], [0,0,3]] Save your function and the main code in a file called matrix.py and upload it here.

Question

Matrix Multiplication by a Scalar
Please write a function calculate (matrix, scalar) that takes two arguments: a nested list that
represents a matrix and an integer that represents a scalar. The function returns a nested list
that corresponds to the result of matrix multiplication by a scalar. Your function should work
with the following code:
if __name__ == '__main__':
scalar
3
A = [[1,0,0], [0,1,0], [0,0,1]]
D calculate (A, scalar)
assert D == [[3,0,0], [0,3,0], [0,0,3]]
Save your function and the main code in a file called matrix.py and upload it here.

Common Time Zones Function Name: commonTimeZones() Parameters: code1( str ), code2( str) Returns: list of common time zones ( list ) Description: You and your friend live in different countries, but you figure there's a chance that both of you might be in the same time zone. Thus, you want to find out the list of possible time zones that you and your friend could both be in. Given two country codes, write a function that returns a list of the time zones the two countries have in common. Be sure not to include any duplicate time zones. If the two country codes do not have any common time zones, return the string 'No Common Time Zones' instead. Note: You can assume that the codes will always be valid. example test cases: >>> commonTimeZones('can', 'usa') [UTC-08:00', 'UTC-07:00', 'UTC-06:00', 'UTC-05:00', 'UTC-04:00] >>> commonTimeZones('rus', 'chn') [UTC+08:00] For this assignment, use the REST countries API (https://restcountries.com/#api-endpoints-v2).

] ] has_perfect You are to write a function has "perfect (graph)" that takes in a BIPARTITE graph as its input, and then determintes whether or not the graph has a perfect matching. In other words, it will return the Boolean value True if it has one, and False if it does not. After compiling the above cell, you should be able to compile the following cell and obtain the desired outputs. print (has perfect({"A" : ["B", "C"], "B" : ["A", "D"], "C" : ["A", "D"], "D" : ["B", "C"]}), has perfect ( {"A" : ["B"], "B" : ["A", "D", "E"], "C" : ["E"], "D":["B"], "E": ["B","C","F"], "F":["E"]})) This should return True False Python Python
Problem DNA: Subsequence markingA common task in dealing with DNA sequences is searching for particular substrings within longer DNA sequences. Write a function mark_dna that takes as parameters a DNA sequence to search, and a shorter target sequence to find within the longer sequence. Have this function return a new altered sequence that is the original sequence with all non-overlapping occurrences of the target surrounded with the characters >> and <<. Hints: ● String slicing is useful for looking at multiple characters at once. ● Remember that you cannot modify the original string directly, you’ll need to build a copy. Start with an empty string and concatenate onto it as you loop. Constraints: ● Don't use the built-in replace string method. All other string methods are permitted. >>> mark_dna('atgcgctagcatg', 'gcg') 'at>>gcg<<ctagcatg' >>> mark_dna('atgcgctagcatg', 'gc')…
PYTHON Problem Statement Given a list of numbers (nums), for each element in nums, calculate how many numbers in the list are smaller than it. Write a function that does the calculation and returns the result (as a list). For example, if you are given [6,5,4,8], your function should return [2, 1, 0, 3] because there are two numbers less than 6, one number less than 5, zero numbers less than 4, and three numbers less than 8. Sample Input smaller_than_current([6,5,4,8]) Sample Output [2, 1, 0, 3]
