The interact function provides a high-level interface for creating user interface controls to use in exploring code and data interactively.

Basic interact

Here is a simple function that displays its arguments as an HTML table:



In [2]:

    
def show_args(**kwargs):
    s = '<h3>Arguments:</h3><table>\n'
    for k,v in kwargs.items():
        s += '<tr><td>{0}</td><td>{1}</td></tr>\n'.format(k,v)
    s += '</table>'
    display(HTML(s))



In [3]:

    
show_args(a=10, b='Hi There', c=True)









    




Arguments:

a 10
c True
b Hi There

Let's use this function to explore how interact works.



In [4]:

    
i = interact(show_args,
         Temp=(0,10),
         Current=(0.,10.,0.01),
         z=True,
         Text=u'Type here!',
         #Algorithm=['This','That','Other'],
         a=widgets.FloatSliderWidget(min=-10.0, max=10.0, step=0.1, value=5.0, description="Float (a)")
         )









    




Arguments:

Current 4.99
Text Type here!
z True
Temp 5
Float (a) 5.0



In [5]:

    
i.widget









    




Arguments:

Current 4.99
Text Type here!
z True
Temp 5
Float (a) 5.0
