Introduction to Pandas Series - Pandas Series
A Series
is a one-dimensional labeled array in pandas that can hold any data type such as integers, strings, floating-point numbers, Python objects, etc. It is similar to a column in a spreadsheet or a SQL table. It is a fundamental data structure for the pandas library.
Syntax
The basic syntax to create a Series
in Pandas is as follows:
import pandas as pd
# Create a Series
s = pd.Series(data, index=index)
Here, data
can be a Python dictionary, an ndarray, a scalar value, or a list, and index
is a list of axis labels. Both data
and index
are optional.
Example
Consider the following example, where we create a Series
object in Pandas:
import pandas as pd
# Create data
data = {'apples': 10, 'oranges': 5, 'pears': 7}
# Create a Series
s = pd.Series(data)
print(s)
In this example, we create a dictionary data
with some data, and then we create a Series
object s
in Pandas using this data. We print the Series
object using print(s)
.
Output
When the above program is executed, it produces the following output:
apples 10
oranges 5
pears 7
dtype: int64
This output shows the values in the Series
object along with their corresponding index labels.
Explanation
The Series
object in Pandas is a one-dimensional labeled array that can hold data of any type. It is similar to a NumPy array but with an index.
In the example above, we create a dictionary data
with some data, and then we create a Series
object s
in Pandas using this data. The resulting Series
object has three values, each with an index label.
Use
The Series
object in Pandas is useful for creating and manipulating one-dimensional labeled data. It can be used to perform operations on data, such as filtering, sorting, aggregation, and statistical computations.
Important Points
- A
Series
is a one-dimensional labeled array in Pandas. - It can hold data of any type.
- It is similar to a column in a spreadsheet or a SQL table.
Summary
The Series
object is a fundamental data structure in Pandas that is used to create and manipulate one-dimensional labeled data. It is a powerful tool that can be used for various data manipulation, filtering, and computation operations.
