It is a very convenient module as this module helps in importing matplotlib.pyplot (for the plotting) and NumPy (for the mathematics and working with arrays) in bulk in a single namespace. NOTE: Pylab conflicts with all sorts of built-in functions in Python, so it is abandoned and is not used much. Syntax to import the Pylab module

from numpy import * from pylab import * x = linspace(-3, 3, 30) y = x**2 plot(x, y) show(). The above line of code generates the following output −.

PyLab is a module that belongs to the Python mathematics library Matplotlib. PyLab combines the numerical module numpy with the graphical plotting module pyplot. PyLab was designed with the interactive Python interpreter in mind, and therefore many of its functions are short and require minimal typing.
