Understanding matplotlib xticks syntax

Question

I am reading a book and I came across this code:

import matplotlib.pyplot as plt
plt.scatter(x,y)
plt.title(\"Web traffic over the last month\")
plt.xlabel(\"Tim         


        

Answer 1

In order to understand range, open python and write in sequence the following commands:

 range(7) 
 range(4,8) 
 range(3,11,2)

For the list comprehensions within the plt.xticks, they are basically a compact way of writing loops. They are very common, useful and neat. In order to understand them:

 [w*2 for w in range(10)] 
 [w*2 for w in range(10) if w < 4] 

Finally, for the command plt.xticks itself you can check http://matplotlib.org/api/pyplot_api.html#matplotlib.pyplot.xticks for a very brief explanation with simple examples.
