What is Python used for?
Python is an interpreted, general-purpose high-level programming language whose design philosophy emphasises code readability Clear syntax Multiple programming paradigms Dynamic typing Strong on-line community Rich documentation Numerous libraries Expressive features Fast prototyping Can be slow Beware when you are analysing very large networks
What is a virtual environment in Python?
Virtual environments are independent groups of Python libraries, one for each project. Packages installed for one project will not affect other projects or the operating system’s packages. Python comes bundled with the venvmodule to create virtual environments. 4 Chapter 1. User’s Guide
Is Python's NumPy slow?
Can be slow Beware when you are analysing very large networks Introduction: Python’s Holy Trinity NumPy is an extension to include multidimensional arrays andmatrices. Both SciPy and NumPy rely on the C library LAPACK for very fast implementation. 6 Matplotlib is the primary plotting library in Python. Supports 2-D and 3-D plotting.

Measuring Memory Use Measuring the memory use of a Python program in a portable way was not an entirely easy task until somewhat recently. Yes, you could always go view the Python process in the system task viewer, but there were no standard library modules to help you out. This changed somewhat in Python 2.6 with the addition of

On a typical Linux platform, this program will allocate memory very rapidly, filling up the available real memory. Then the Kernel Swap Daemon (kswapd) will be invoked to swap pages of memory out to the swap file. Fairly soon, the swap file fills up and the program may be killed by the operating system (thereby freeing up all of the memory ...

Arrow is a columnar in-memory analytics layer designed to accelerate big data. It houses a set of canonical in-memory representations of flat and hierarchical data along with multiple language-bindings for structure manipulation. It also provides IPC and common algorithm implementations. This is the documentation of the Python API of Apache Arrow.

3) The Python module written below reads in an integer number N given by the user and checks if it is “perfect” (A number N is perfect if it is equal to the sum of its divisors, excluding itself; for example, N=6 is perfect: its divisors are 1,2 and 3 and 1+2+3=6).

As other software usually do, python also can “load” external libraries. The command to import a library is . import. followed by the name of the library. The caveat is that you should know what that name is! Libraries may be built in the operating system installation or part of the python installed but not loaded when python is started.

However, it does not come standard with the python software and has to be installed first. How the installation is done varies with the operating system and the python software used. numpy has already been installed on the computer you are using in class. However, if you are trying to do this on your own computer you will need to install numpy.

Python has support for all the regular numeric data types, including integers, floating-point decimals, and even complex numbers. There are plain integers, (in the range -2147483648 through 2147483647), long integers (in unlimited range, subject only to available memory), and Booleans, which can only be 0 (False) or 1 (True).

Some of the functions that you have used are input, raw_input, and range. Python has many other library functions. The random Function. In order to use the random function in Python, you must import the random library. This loads the library into memory so that you can use the functions that exist within it.
