I am having hard time to figure out how to find min from a list for example
somelist = [1,12,2,53,23,6,17] how can I find min and max of this list with defining (def) a function
I do not want to use built-in function min
232
Keep a minimum variable that is initialized to a high value, and update it if you see a lower value. Do the opposite with a maximum variable. Add up all numbers and divide that sum by the total count to get the average.
The average is the sum of all the numbers in a list divided by its length.
How to calculate the minimum of a list of numbers? To find the smallest value (the minimum) among a list of numbers, it is necessary to go through the whole list of numbers and compare their values one after the other. The minimum in the list is the smallest value found when all values have been compared.
from __future__ import division somelist = [1,12,2,53,23,6,17] max_value = max(somelist) min_value = min(somelist) avg_value = 0 if len(somelist) == 0 else sum(somelist)/len(somelist) If you want to manually find the minimum as a function:
somelist = [1,12,2,53,23,6,17] def my_min_function(somelist): min_value = None for value in somelist: if not min_value: min_value = value elif value < min_value: min_value = value return min_value Python 3.4 introduced the statistics package, which provides mean and additional stats:
from statistics import mean, median somelist = [1,12,2,53,23,6,17] avg_value = mean(somelist) median_value = median(somelist) Return min and max value in tuple:
def side_values(num_list): results_list = sorted(num_list) return results_list[0], results_list[-1] somelist = side_values([1,12,2,53,23,6,17]) print(somelist) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
