Installation of NumPy

If you have Python and PIP already installed on a system, then installation of NumPy is very easy.

Install it using this command:

python

C:\Users\Your Name>pip install numpy

If this command fails, then use a python distribution that already has NumPy installed like, Anaconda, Spyder etc.

Once NumPy is installed, import it in your applications by adding the import keyword:

python

import numpy

Now NumPy is imported and ready to use.

python

import numpy

arr = numpy.array([1, 2, 3, 4, 5])

print(arr)

NumPy is usually imported under the np alias.

Note: alias: In Python alias are an alternate name for referring to the same thing.

Create an alias with the as keyword while importing:

python

import numpy as np

Now the NumPy package can be referred to as np instead of numpy.

python

import numpy as np

arr = np.array([1, 2, 3, 4, 5])

print(arr)

The version string is stored under __version__ attribute.

python

import numpy as npprint(np.__version__)
