Question
The function sum_evens in python takes a list of integers and returns the sum of all the even integers in the list.
For example:
Test | Result |
---|---|
print(sum_evens([1, 5, 2, 5, 3, 5, 4])) | 6 |
print(sum_evens([5, 5, -5, -5])) | 0 |
print(sum_evens([16, 24, 30])) | 70 |

- IN PYTHON: Using a function, create a list of 20 numbers randomly between 1-99. With recursive function, you are going to take the numbers from the list, one at a time starting at position 0 and add them together. If the numbers added together equals a user specified sum, stop the program and show the two digits that sum together. If not, remove the first number from the list and add the next two. Continue running the program until you have reached the end of the list. sample output: randomly selected numbers: [61, 6, 78, 3, 64, 22, 11, 9, 34, 99, 31, 56, 43, 8, 77, 27, 93, 47, 58, 20] User input : 86 61 + 6 = 67 FALSE [6, 78, 3, 64, 22, 11, 9, 34, 99, 31, 56, 43, 8, 77, 27, 93, 47, 58, 20] 6 + 78 = 84 FALSE [78, 3, 64, 22, 11, 9, 34, 99, 31, 56, 43, 8, 77, 27, 93, 47, 58, 20] 78 + 3 = 81 FALSE [3, 64, 22, 11, 9, 34, 99, 31, 56, 43, 8, 77, 27, 93, 47, 58, 20] 3 + 64 = 67 FALSE [64, 22, 11, 9, 34, 99, 31, 56, 43, 8, 77, 27, 93, 47, 58, 20] 64 + 22 = 86 TRUE!arrow_forwardDefine a python function that is passed a table (2D list of lists) of integers and returns the total of all the integers in the table. def total(T): """" Returns the sum of all the elements in the integer table T"""arrow_forwardpython Write a function which accepts two sequences of numbers from the user, each number separated by a comma and generates a list of common numbers between the two sequences.

- Python Qu Write a Python program (not a function!) that asks the user for nonnegative integers,one integer per line.When the user is finished entering their integers, they enter a negative integerto tell the program to stop asking them for more integers.Once the input is complete, the program prints "No integers to average"if the user provided no nonnegative integers,and the average of the nonnegative integers otherwise.You must NOT use lists, tuples, or dictionaries in your code.Here is a sample program run where the user enters 4 and then 8 and then -1.The program outputs Average: 6.048-1Average: 6.0Here is another run where the user types -3 to the first prompt.The program outputs No integers to average-3No integers to averagearrow_forwardIn Python, program a function that multiplies c numbers in a list and returns the product, when c < 2.arrow_forwardPlease help.

- python LAB: Subtracting list elements from max When analyzing data sets, such as data for human heights or for human weights, a common step is to adjust the data. This can be done by normalizing to values between 0 and 1, or throwing away outliers. Write a program that adjusts a list of values by subtracting each value from the maximum value in the list. The input begins with an integer indicating the number of integers that follow.arrow_forwardTo determine if two lists of integers are equivalent, you must write a function that accepts the lists as input and returns true or false (i.e. contain the same values). The greatest value of each list must be shown if the lists are dissimilar and the procedure is effective.arrow_forwardQuestion in image Please explain the algorithm with the answer.
