Creating a line plot in python using data from a-for loop
Question: I have some previous code which will print out

'The number for january is x' - etc, throughout one year.

I'm trying to plot the x vs the months using this:

    
    
    import matplotlib.pyplot as plt
    for m, n in result.items():
        print 'The number for', m, "is", n
        plt.plot([n])
        plt.ylabel('Number')
        plt.xlabel('Time (Months)')
        plt.title('Number per month')
        plt.show()
    

Where m is the month (also the file name it reads from and n is the x value
(number).

However when I run this I just get a blank graph - I think I may be missing
somethhing major out?

Result contains:

    
    
    {'apr': 13, 'jun': 13, 'jul': 13, 'aug': 13, 'sep': 13, 'oct': 13} x 6 times 
    

For practical purposes I made each file have a number of 13 as the real files
are enormous


Answer: 
    import matplotlib.pyplot as plt
    import numpy as np 
    
    result = {'apr': 13, 'jun': 13, 'jul': 13, 'aug': 13, 'sep': 13, 'oct': 13}
    for m, n in result.items():
        print 'The number for', m, "is", n
    plt.plot(result.values())
    plt.ylabel('Number')
    plt.xlabel('Time (Months)')
    plt.title('Number per month')
    plt.xticks(range(len(result)), result.keys())
    plt.show()
    

So what I have done here is to just remove the plotting section outside the
`for` loop. Now you will get your results printed as you have been doing
previously, but the plotting will be done for all the values once.

You can take out the values from a dictionary using `dict.values`, in our case
gives us all the many values which are `13`.
