# Python Median of List – It Can’t Get Easier than This

This short tutorial will teach how to use Python for the median of the list and set and how to use Numpy to find the median of an array – matrix columns and rows.

## Python Median of List

In python, you can use the native module statistics and import median to compute the median of a list or set as we show below

```import statistics

my_list = [1, 2, 3, 4]

list_median = statistics.median(my_list)

my_set = {1, 2, 3, 4}

set_median = statistics.median(my_set)

print("The List Median is {}".format(list_median))

print("The Set Median is {}".format(set_median))
```

Which should print

```The List Median is 2.5
The Set Median is 2.5
```

## Numpy Median of Array – Matrix

In case you need to find the median for the columns or rows of a matrix, you can use numpy.

```import numpy

# create matrix
my_matrix = [[1, 2, 3, 4], [1, 1, 1, 1]]

# axis=1 will find the median for the rows
matrix_rows_median = numpy.median(my_matrix, axis=1)

# axis=0 will find the median for the columns
matrix_columns_median = numpy.median(my_matrix, axis=0)

print("The Matrix rows Medians are {}".format(matrix_rows_median))
print("The Matrix Columns Medians are {}".format(matrix_columns_median))
```

which should print

```The Matrix rows Medians are [2.5 1. ]
The Matrix Columns Medians are [1.  1.5 2.  2.5]
```
