Multiplying Values of Pandas Series

Multiplying Values of Pandas Series

Let's find out how a pandas series works with the all method and equality operator.

We'll cover the following...

Try it yourself

Try executing the code below to see the result.

Python 3.8
import pandas as pd
v = pd.Series([.1, 1., 1.1])
out = v * v

1 1.00
2 1.21
dtype: float64
In [2]: expected
Out[2]:
0 0.01
1 1.00
2 1.21
dtype: float64

But, when we compare them, ...
