Find average of a list in pythonPrerequisites: sum() function, len() function, round() function, reduce(), lambda, and mean(). Show
Given a list of numbers, the task is to find average of that list. Average is the sum of elements divided by the number of elements. Examples: Input : [4, 5, 1, 2, 9, 7, 10, 8] Output : Average of the list = 5.75 Explanation: Sum of the elements is 4+5+1+2+9+7+10+8 = 46 and total number of elements is 8. So average is 46 / 8 = 5.75 Input : [15, 9, 55, 41, 35, 20, 62, 49] Output : Average of the list = 35.75 Explanation: Sum of the elements is 15+9+55+41+35+20+62+49 = 286 and total number of elements is 8. So average is 46 / 8 = 35.75Python AverageThe Python Average function is used to find the average of given numbers in a list. The formula to calculate average in Python is done by calculating the sum of the numbers in the list divided by the count of numbers in the list. The Python average of list can be done in many ways listed below:
In this Python tutorial, you will learn how to calculate average in Python:
Python AverageThere are two methods employed to find the average of a list of numbers in Python:
While both methods return the average of a list of numbers, there are different factors you should consider when choosing which one to use. In this tutorial, we discuss how to use the aforementioned approaches to find the average of a list in Python. We’ll walk through two examples to help you get started. How to Find Average of A List in PythonIn this article, we will learn to find the average of a list of elements using Python script. We will use some built-in functions and some custom codes as well. Let's first have a quick look over what is a list and then how we find the average of the list in Python. “average value of list elements in python” Code Answeraverage value of list elements in python python by Comfortable Cow on Feb 14 2020 Comment 14 Source: www.guru99.com Add a Grepper Answer Python answers related to “average value of list elements in python”

Python List Average MedianWhat’s the median of a Python list? Formally, the median is “the value separating the higher half from the lower half of a data sample” (wiki). How to calculate the median of a Python list?
Together, you can simply get the median by executing the expression median = sorted(income)[len(income)//2]. Here’s the concrete code example: income = [80000, 90000, 100000, 88000] average = sum(income) / len(income) median = sorted(income)[len(income)//2] print(average) # 89500.0 print(median) # 90000.0Related tutorials:
Python List Average MeanThe mean value is exactly the same as the average value: sum up all values in your sequence and divide by the length of the sequence. You can use either the calculation sum(list) / len(list) or you can import the statistics module and call mean(list). Here are both examples: lst = [1, 4, 2, 3] # method 1 average = sum(lst) / len(lst) print(average) # 2.5 # method 2 import statistics print(statistics.mean(lst)) # 2.5Both methods are equivalent. The statistics module has some more interesting variations of the mean() method (source):
These are especially interesting if you have two median values and you want to decide which one to take. Python List Average Standard DeviationStandard deviation is defined as the deviation of the data values from the average (wiki). It’s used to measure the dispersion of a data set. You can calculate the standard deviation of the values in the list by using the statistics module: import statistics as s lst = [1, 0, 4, 3] print(s.stdev(lst)) # 1.8257418583505538Python List Average Min MaxIn contrast to the average, there are Python built-in functions that calculate the minimum and maximum of a given list. The min(list) method calculates the minimum value and the max(list) method calculates the maximum value in a list. Here’s an example of the minimum, maximum and average computations on a Python list: import statistics as s lst = [1, 1, 2, 0] average = sum(lst) / len(lst) minimum = min(lst) maximum = max(lst) print(average) # 1.0 print(minimum) # 0 print(maximum) # 2 |
