PYTHON

python list and numpy array

if your have height and weight of your family memberas a list in two variables 
like weight=[25,46,81,70] and height=[180,140,160,155] in order then your 
cannot perform operations like calculating BMI=weight/(height)**2 or any other because python
list contains different data types and numerical operations is impossible. And,
also in python list the operation of bmi cannot be cannot calculated by using
indexed list of weight and similar height. So for this, numpy array is the
solution where your convert python list to numpy array and can do literaaly 
anything that python list cannot
