Good news is that in Python 3 range, d.items() etc return generators (in Python 2 use xrange, d.iteritems() respectively). (Donald Knuth). Intermediate. Space is saved because __dict__ is not created for each instance', so this is really useful if you have a lot of instances (here is a real-world example). Numpy to get arrays in Python, Pandas to manipulate the data, pandas_datareader to get the stock data that we need, matplotlib.pyplot to make a visual representation of our efficient frontier. I'm trying to create a simple fuel calculation program below and feel i had to type so much code in order to get input from a user and convert that string input back to either a float or int. Using single letters does not make your code more efficient, in fact quite the opposite, because it is more difficult t understand. I am trying to "stitch" together any two of the entries in lst2 to form a loop of twelve words using the word pairs from lst1 by matching the beginning and ending words in lst2 … If you were to look, Data, data, and more data.
