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 ylim() function in pyplot module of matplotlib library is used to get or set the y-limits of the current axes.Python3 1== Output:
Example #2:Python3 1== Output: 
matplotlib.pyplot.ylim() Function
Syntax: matplotlib.pyplot.ylim(*args, **kwargs) Parameters: This method accept the following parameters that are described below:Below examples illustrate the matplotlib.pyplot.ylim() function in matplotlib.pyplot: Example #1:Returns: This returns the following:
- bottom: This parameter is used to set the ylim to bottom.
- top: This parameter is used to set the ylim to top.
- **kwargs: This parameter is Text properties that is used to control the appearance of the labels.
- bottom, top :This returns the tuple of the new y-axis limits.
