How it works...

The simplest constructor for a Series object takes as argument a Python iterable, as shown in the first example, reproduced as follows:

series1 = pd.Series(['Alice', 'Bob', 'Joe', 'Mary'])series1

The iterable must be one-dimensional, such as a plain list, a NumPy array, or a file object with a stream of data. The preceding code will create the following Series object:

0    Alice
1      Bob
2      Joe
3     Mary
dtype: object

The first column in the display is the index, which is a pandas object of type Index. The default index uses integers, starting at 0. Also notice that a Series object has a specific data type, represented by a NumPy dtype object. In this example, the data in the Series object consists of strings, so the dtype is object ...
