Initial Notebook Tutorial

So this is some text.

Below we can see that python knows how to add up some numbers



In [2]:

    
1+3









    Out[2]:





4

And, if we give it some strings, it does something different!



In [3]:

    
"Hello " + "world!"









    Out[3]:





'Hello world!'

Do we have state?



In [5]:

    
variable = 1

let's check



In [7]:

    
print(variable + 4)

And what if we produce an error?



In [8]:

    
print(variable + "hello")









    



---------------------------------------------------------------------------
TypeError                                 Traceback (most recent call last)
<ipython-input-8-8e5fb4994266> in <module>()
----> 1 print(variable + "hello")

TypeError: unsupported operand type(s) for +: 'int' and 'str'

Let's check if we can import some module



In [11]:

    
from pylab import *
from matplotlib.patches import Ellipse

Initialize some data



In [12]:

    
delta = 45.0 # degrees

angles = arange(0, 360+delta, delta)
ells = [Ellipse((1, 1), 4, 2, a) for a in angles]

a = subplot(111, aspect='equal')

for e in ells:
    e.set_clip_box(a.bbox)
    e.set_alpha(0.1)
    a.add_artist(e)

xlim(-2, 4)
ylim(-1, 3)









    Out[12]:





(-1, 3)

And plot!



In [13]:

    
show()

That's nice. We should see now if we can include some code as example.
