Python is already installed in Fedora OS quite similar to Ubuntu. Now, you just have to use pip command in order to proceed with the NumPy installation. However, do not forget to notice the difference in usage of pip command in Fedora OS for Python3. Now that we have installed Numpy, we shall get to know how to work with Numpy.
To use Numpy package, one has to first import the package to use the functionalities of Numpy. Every time you want to use submodules of Numpy, you have to refer to the parent module name Numpy. So we can assign an alias name to Numpy, after assigning an alias name Numpy can be called with that assigned alias name. We have imported Numpy, now let us start coding using Numpy. Initially, we have seen Numpy is fast, let us write a code to check that.
I have used jupyter Notebook to write my codes. To check the time taken by Numpy and the normal list a data type in python , we are using a time package. The output shown clearly shows that Numpy has taken very little time to complete when compared to the normal list. Explore Now! Click Here — Get Prepared for Interviews! Click Here — Enroll Now!

PyPI is the largest collection of packages by far, however, all popular packages are available for conda as well. The third difference is that conda is an integrated solution for managing packages, dependencies and environments, while with pip you may need another tool there are many!
As libraries get updated, results from running your code can change, or your code can break completely. Best practice is to:. Functions, groups, and variables can all be described in a module.
Runnable code can also be used in a module. A module can be imported by multiple programs for their application, hence a single code can be used by multiple programs to get done with their functionalities faster and reliably. Installing Python modules on Windows Check pip is installed or not: To check whether pip is installed or not, run the following command in windows using the command prompt: pip --version Output:.

Improve Article. This documentation is retained as a reference only, and will be removed with the package. The up to date module installation documentation.
For regular Python usage, you almost certainly want that document rather than this one. This guide only covers the basic tools for building and distributing extensions that are provided as part of this version of Python. Third party tools offer easier to use and more secure alternatives. Refer to the quick recommendations section in the Python Packaging User Guide for more information.
In Python 2. This provided Linux distro maintainers with a standard way of converting Python projects into Linux distro packages, and system administrators with a standard way of installing them directly onto target systems. In the many years since Python 2. If you download a module source distribution, you can tell pretty quickly if it was packaged and distributed in the standard way, i.
Next, the archive will unpack into a similarly-named directory: foo Additionally, the distribution will contain a setup script setup. Or rather, the above command is everything you need to get out of this manual.
As described in section Distutils based source distributions , building and installing a module distribution using the Distutils is usually one simple command to run from a terminal:. You should always run the setup command from the distribution root directory, i. Then, open a command prompt window and run:. Running setup. If you prefer to work incrementally—especially useful if you want to customize the build process, or if things are going wrong—you can use the setup script to do one thing at a time.
This is particularly helpful when the build and install will be done by different users—for example, you might want to build a module distribution and hand it off to a system administrator for installation or do it yourself, with super-user privileges. For example, you can build everything in one step, and then install everything in a second step, by invoking the setup script twice:. If you do this, you will notice that running the install command first runs the build command, which—in this case—quickly notices that it has nothing to do, since everything in the build directory is up-to-date.
As implied above, the build command is responsible for putting the files to install into a build directory. For example:. Or you could do this permanently with a directive in your system or personal Distutils configuration file; see section Distutils Configuration Files. In that case, the temp. In either case, the lib or lib. In the future, more directories will be added to handle Python scripts, documentation, binary executables, and whatever else is needed to handle the job of installing Python modules and applications.
They are always the same under Windows, and very often the same under Unix and macOS. You can find out what your Python installation uses for prefix and exec-prefix by running Python in interactive mode and typing a few simple commands. Under Unix, just type python at the shell prompt. Once the interpreter is started, you type Python code at the prompt.
For example, on my Linux system, I type the three Python statements shown below, and get the output as shown, to find out my prefix and exec-prefix :. A few other placeholders are used in this document: X. Y stands for the version of Python, for example 3. Dots and capitalization are important in the paths; for example, a value that uses python3.
If you want to customize your installation directories more heavily, see section Custom Installation on custom installations. Often, it is necessary or desirable to install modules to a location other than the standard location for third-party Python modules.
For example, on a Unix system you might not have permission to write to the standard third-party module directory. Or you might wish to try out a module before making it a standard part of your local Python installation.
This is especially true when upgrading a distribution already present: you want to make sure your existing base of scripts still works with the new version before actually upgrading.
The Distutils install command is designed to make installing module distributions to an alternate location simple and painless.
