zeroTriples.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then find all triples in the list that sum to zero. You can assume the list won’t contain any duplicates, and a triple should not use the same number more than once. For example:$ python3 zeroTriples.py124-123450 triples found $ python3 zeroTriples.py-3142-123451 triple found:1, 2, -3 $ python zeroTriples.py-91-3245-4-1-123454 triples found:-9, 4, 51, -3, 2-3, 4, -15, -4, -1

statistics.py: Write a program that reads a list of integers from the user, until they enter -12345 (the -12345 should not be considered part of the list). Then print the mean, median, and standard deviation of the list. The mean is the average of the numbers. The median is the “middle” value if n is odd, or the average of the two “middle” values if n is even. The standard deviation is the average amount of variability For example: $ python3 statistics.py154102-12345mean: 7.75median: 7standard deviation: 5.909032633745278
