I am working on the file "Assignment1/Assignment1.ipynb".
The first task is:
We use pandas to read, group, and sort our data:
Can you write Python program for it?

Can you provide a the Python program you requested?

#Here is the Python program you requested.

def read_data():
    d = pandas.read_csv(_DATA_FILEPATH)

    return d
    
def process_data(d):
    # Group by organization.

    def sum_views(df):
        return sum(df['Views per Month'])

    g = d.groupby('Organization Name').apply(sum_views)

    # Sort by views (descendingly).

    g.sort(ascending=False)

    # Grab the first N to plot.

    items = g.iteritems()
    s = itertools.islice(items, 0, _ORGANIZATION_COUNT)

    s = list(s)

    # Sort them in ascending order, this time, so that the larger ones are on 
    # the right (in red) in the chart. This has a side-effect of flattening the 
    # generator while we're at it.
    s = sorted(s, key=lambda (n, v): v)

    # Truncate the names (otherwise they're unwieldy).

    distilled = []
    for (name, views) in s:
        if len(name) > (_MAX_LABEL_LENGTH - 3):
            name = name[:17] + '...'

        distilled.append((name, views))

    return distilled
