Hello Joe, I personally think it would be nice if you make videos on all the data-science libraries and make a separate playlist of it.(Pandas, scikit, matplotliib, scipy and also maybe tensorflow, theano, nltk).
Your channel is like a Python pit-stop on Youtube and it would really help if you included all(or most of) these things mentioned above so that we don't have to look anywhere else for anything.

np.random.randint is NOT inclusive of the last element of the range given. np.random.randint(0, 10, 5) returns random integers between 0 and 9.

Numpy also allows you to compare 2D arrays to 1 D arrays. Which is is super useful.

b = 2D array (3x2) < 1D array (2)
print (b)
[ [ True, False ], [ etc, etc ] [ etc, etc ] ]

Thanks Joe. It was very helpful to get me started with Numpy.

Great video, very instructive!
Concerning the example you gave at the beginning of your video, I also believe that using list comprehension would have done the trick, in a still very "pythonic" way:
Your code was :

for i in range(len(my_list)):
my_list[i] *= 3

And I would suggest:

my_list = [i*3 for i in range(len(my_list))]

Thanks and keep up the good work :D
