Matplotlib is a library in Python and it is numerical - mathematical extension for NumPy library. Pyplot is a state-based interface to a Matplotlib module which provides a MATLAB-like interface.The grid() function in pyplot module of matplotlib library is used to configure the grid lines.Python3 1== 
Example #2:Python3 1== 
matplotlib.pyplot.grid() Function
Syntax: matplotlib.pyplot.grid(b=None, which='major', axis='both', \*\*kwargs) Parameters: This method accept the following parameters.Below examples illustrate the matplotlib.pyplot.grid() function in matplotlib.pyplot: Example #1:Returns:This method does not return any value.
- b : This parameter is an optional parameter, whether to show the grid lines or not.
- which : This parameter is also an optional parameter and it is the grid lines to apply the changes on.
- axis :This parameter is also an optional parameter and it is the axis to apply the changes on.
