The term “heatmap” has two different meanings in Python:

1. Matplotlib Heatmap:

heatmap is a function in the Matplotlib library that creates a heatmap. A heatmap is a graphical representation of data that uses color to show the intensities of values in a matrix. Each element in the matrix is colored based on its value, with different colors representing different levels of intensity.

Here is an example of how to use the heatmap function to create a heatmap:

“`pythonimport matplotlib.pyplot as plt

Create a sample data matrix

data = [[10, 20, 30], [20, 30, 40], [30, 40, 50]]

Create a heatmap

plt.heatmap(data)

Show the heatmap

plt.show()“`

This code will create a heatmap with three rows and three columns, where the values in the data matrix are represented by different colors.

2. Pandas Heatmap:

The heatmap function is also available in the Pandas library. In this context, the heatmap function is used to visualize a correlation matrix between variables in a DataFrame.

Here is an example of how to use the heatmap function to create a heatmap of a Pandas DataFrame:

“`pythonimport pandas as pd

Create a sample DataFrame

df = pd.DataFrame({“A”: [10, 20, 30], “B”: [20, 30, 40], “C”: [30, 40, 50]})

Create a heatmap

df.heatmap()“`

This code will create a heatmap showing the correlations between the variables in the DataFrame.
