Hints to know



In [2]:

    
print("Hello man")









    



Hello man

Example code block

Timing code



In [1]:

    
def fibo(n):
    if n == 0:
        return 0
    elif n == 1:
        return 1
    return fibo(n-1) + fibo(n-2)



In [2]:

    
%timeit fibo(20)









    



100 loops, best of 3: 4.63 ms per loop

Note: Also it's possible to use %%timeit for the whole code block

Plotting



In [9]:

    
%matplotlib inline
%config InlineBackend.figure_format = 'retina'

import matplotlib.pyplot as plt
import numpy as np



In [10]:

    
x = np.linspace(0, 1, 300)
for w in range(2, 6, 2):
    plt.plot(x, np.sin(np.pi*x)*np.sin(2*w*np.pi*x))

Debugging with %pdb



In [11]:

    
%pdb









    



Automatic pdb calling has been turned ON
