Using numpy in python

• How NumPy arrays are better than Python list?

  What makes NumPy better than Python list? NumPy consumes less memory than the python list. Python Numpy is fast and more compact as compared to a python list. NumPy is much convenient to use than a python list. Numpy is faster as it uses C API and for most of its operation, we don't need to use any looping operation.

• Is NumPy necessary for data analysis in Python?

  NumPy based arrays are 10 to 100 times (even more than 100 times) faster than the Python Lists, hence if you are planning to work as a Data Analyst or Data Scientist or Big Data Engineer with Python, then you must be familiar with the NumPy as it offers a more convenient way to work with Matrix-like objects like Nd-arrays.

• How do I install NumPy?

  In most use cases the best way to install NumPy on your system is by using a pre-built package for your operating system. Please see http://scipy.org/install.html for links to available options. For instructions on building for source package, see Building from source. This information is useful mainly for advanced users.

• Does Python come with NumPy library as 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.

  When reading files you can use standard Python, use lists, allocate ndarrays and fill them. Or use any of NumPy’sI/O routines that will directly generate ndarrays. The best way depends on the structure of your data. If dealing with structured numeric data (tables of numbers, etc.) NumPy is easier and faster.
