find the median of all values in a map in python

You can find the median of all values in a python map or dictionary using the statistics module. Here's an example code snippet:

main.py
import statistics

# create a sample map
my_map = {'a': 5, 'b': 10, 'c': 15, 'd': 20}

# get all values from the map using .values() method
values = my_map.values()

# calculate the median using the statistics module
median = statistics.median(values)

# print the median
print('The median of all values in the map is:', median)

In the above code, we first import the statistics module. Then we create a sample map called my_map. We get all the values from the map using the .values() method, and store them in a variable called values. Finally, we calculate the median of the values using the statistics.median() method, and print out the result.
