Fun Python list related problems
Sum the Numbers Given an list of numbers, print their sum. When I say given something, just make something up and store it in a variable.
Largest Number Given an list of numbers, print the largest of the numbers.
Smallest Number Given an list of numbers, print the smallest of the numbers.
Even Numbers Given an list of numbers, print each number in the list that is even.
Positive Numbers Given an list of numbers, print each number in the list that is greater than zero.
Positive Numbers II Given an list of numbers, create a new list which contains every number in the given list which is positive.
Multiply a list Given an list of numbers, and a single factor (also a number), create a new list consisting of each of the numbers in the first list multiplied by the factor. Print the new list out to the screen.
Multiply Vectors Given two lists of numbers of the same length, create a new list by multiplying the pairs of numbers in corresponding positions in the two lists. Example:
[2, 4, 5] x [2, 3, 6] = [4, 12, 30]
Matrix Addition Given two two-dimensional lists of numbers of the size 2x2 two dimensional list is represented as an list of lists:
[ [2, -2], [5, 3] ] Calculate the result of adding the two matrices. The number in each position in the resulting matrix should be the sum of the numbers in the corresponding addend matrices. Example: to add
1 3 2 4 and
5 2 1 0 results in
6 5 3 4
Matrix Addition II Use your solution in Matrix Addition, and extend it to work for a pair of matrices of any size, as long as they have the same size.
