# SymPy - Installation

SymPy has one important prerequisite library named mpmath. It is a Python library for real and complex floating-point arithmetic with arbitrary precision. However, Python's package installer PIP installs it automatically when SymPy is installed as follows −

pip install sympy


Other Python distributions such as Anaconda, Enthought Canopy, etc., may have SymPy already bundled in it. To verify, you can type the following in the Python prompt −

>>> import sympy
>>> sympy.__version__


And you get the below output as the current version of sympy −

'1.5.1'
