Is NumPy installed with Python?The only prerequisite for installing NumPy is Python itself. If you don't have Python yet and want the simplest way to get started, we recommend you use the Anaconda Distribution - it includes Python, NumPy, and many other commonly used packages for scientific computing and data science.
Is NumPy in Python by default?NumPy does not come with Python by default so it needs to be installed. As I recommended for the Pandas installation, the easiest way to get NumPy (along with a ton of other packages) is to install Anaconda.
Does NumPy come preinstalled?This programming language comes preinstalled on most operating systems (except Windows; you will need to install Python on Windows manually).
Which Python version has NumPy?The Python versions supported for this release are 3.7-3.9, support for Python 3.10 will be added after Python 3.10 is released.
