Using Python 3, define mySum function that supposed to return the sum of a list of numbers (and 0 if that list is empty), but it has one or more errors in it. Write test cases to determine what errors there are.

Expert Solution

CODE:

def mySum(arr):
if(len(arr)==0):
return 0
else:
return sum(arr)
arr=[1,2,5,4]
print("Sum of list numbers is",mySum(arr))
assert mySum([])==0
print("test pass")
assert mySum([1,2])==0
print("test failed")

Write a Python program that calls a function to sum all the numbers in a list...

Write a Python program that calls a function to sum all the numbers in a list and returns the result to the caller. The main program creates a list (with hard-coded or user input) and passes the list as an argument to the function. You may not use the built-in function, sum. The program calls a second function to multiply all the numbers in a list passed to it by main and returns the product back to the caller. List...

In Python, Complete the longestWord() function to take a list as a parameter and return the length of the longest word in that list. Examples: longestWord(['Python', 'rocks']) returns 5 longestWord(['Casey', 'Riley', 'Jessie', 'Jackie', 'Jaime', 'Kerry', 'Jody']) returns 6 longestWord(['I', 'a', 'am', 'an', 'as', 'at', 'ax', 'the']) returns 3

complete in python The function sumEven should return the sum of only the even numbers contained in the list, lst. Example list_of_nums = [1, 5, 4, 8, 5, 3, 2] x = sum_evens(list_of_nums) print(x) #prints 14 Start your code with def evens(lst):

Python: I am currently a function that will return a list of lists, with the frequency...

Python: I am currently a function that will return a list of lists, with the frequency and the zip code. However, I am having a difficult time organizing the list in decreasing order of frequency. We are asked to use sort () and sorted () instead of lambda. The function will find 5 digit zip codes, and when it sees a 9-digit zip code, the function needs to truncate the last 4 digits. The following is an example of the...

Q2: The following code is supposed to return the sum of the numbers between 1 and n inclusive, for positive n. An analysis of the code using our "Three Question" approach reveals that: int sum(int n){ if (n == 1) return 1; else return (n + sum(n - 1)); } Answer Choices: it passes on all three questions and is a valid algorithm. it fails the smaller-caller question. it fails the base-case question. it fails...

PYTHON! Exercise 3 - Total Line length Write a python function that will return the total length of line that passes through any number of provided points ( (x,y) ). The points should be passed as individual tuples or lists. The function should also have a parameter (True or False) to indicate whether the line should start from the origin, and that parameter should default to False. If True, the returned value should include the distance from the origin to...

Python Question Using lists, write the function non_unique(list) that takes a list list as argument. It returns a list which duplicated elements remains and each duplicated element is followed by a number which shows how many times it appears. All elements in return list should be in the same order as their appearance in the original list. For example, given the input [‘a’, ‘b’, ‘c’, ‘a’, ‘b’, ‘d’, ‘a’,‘e’], the function would return [‘a’, 3, ‘b’, 2]. Another example, ['abc',...

(Python) Implement a function to compute a sum that can compute sum for an arbitrary number of input integers or float numbers. In other words, calls like this should all work: flexible_sum(x1, x2) # sum of two integer or float numbers or strings x1 and x2 flexible_sum(x1, x2, x3) # sum of 3 input parameters and can also handle a single input parameter, returning it unchanged and with the same type, i.e.: flexible_sum(1) returns 1 and can accept an arbitrary...

(Python) a) Using the the code below write a function that takes the list xs as input, divides it into nss = ns/nrs chunks (where nrs is an integer input parameter), computes the mean and standard deviation s (square root of the variance) of the numbers in each chunk and saves them in two lists of length nss and return these upon finishing. Hint: list slicing capabilities can be useful in implementing this function. from random import random as rnd...
