median_low() function in Python statistics module

# Python code to demonstrate the 
# working of median_low()

# importing the statistics module
import statistics

# simple list of a set of integers

# Note: low median will always be
#        a member of the data-set.

# Print low median of the data-set
print("Low median of the data-set is % s "
