Series
Importing Pandas
Before we can start working with Pandas, we need to import it:
import pandas as pd
Defining a Series
We can define a Series in Pandas using the following syntax:
pd.Series(elements_list, index_list)
The following code defines a new Series called populations representing the populations of various cities (in milions):
12345678import pandas as pd populations = pd.Series( [8.9, 3.6, 2.7, 1.6], ["London", "Berlin", "Rome", "Budapest"] ) print(populations)
In some cases you might see the following syntax of creating a Series, which has the same effect, except in this case we use a named parameter to specify the index_list for the sake of readibility:
populations = pd.Series(
[8.9, 3.6, 2.7, 1.6],
index=["London", "Berlin", "Rome", "Budapest"]
)
The index Property
We can access the list of indices of a Series using the index property:
12345678import pandas as pd populations = pd.Series( [8.9, 3.6, 2.7, 1.6], ["London", "Berlin", "Rome", "Budapest"] ) print(populations.index)
1. What does the following code create?
2. What will be the output of the following code?
3. You must always specify the index parameter when creating a Series.
