Understanding Vectorized Operations¶
We'll now compute the revenue in Billions:
In [17]:
revenue_in_billions = revenue_in_millions / 1000
In [18]:
revenue_in_billions
Out[18]:
Apple 274.515 Samsung 200.734 Alphabet 182.527 Foxconn 181.945 Microsoft 143.015 Huawei 129.184 Dell Technologies 92.224 Meta 85.965 Sony 84.893 Hitachi 82.345 Intel 77.867 IBM 73.620 Tencent 69.864 Panasonic 63.191 Name: Top Technology Companies by Revenue, dtype: float64

Subtract $50B from all companies in revenue_in_billions¶
In [15]:
revenue_recession = revenue_in_billions - 50
Create a new series expressing revenue in dollars (units)¶

Operations between Series¶

recession_impact = pd.Series([

The result of applying the recession impact:
In [27]:
revenue_in_millions * recession_impact

We can calculate the dollar amount of the impact by combining multiple operations:
In [28]:
# Absolute impact in Millions
revenue_in_millions - (revenue_in_millions * recession_impact)
