If we are to use this package, we can do so in the following manner: import The _init_.py file is required to make Python treat the directories as containing packages. When importing the package, Python searches through the directories in sys.path looking for the package subdirectory. Here’s a possible package structure to make our lives easier. All of this put together means we would have to write a never-ending stream of modules to handle the combinatorics of data, strategies, and operations.

Also, there are many different strategies and operations that we might need to perform. There are many different data files based on data frequencies, so we may need to create and maintain a growing collection of modules for the conversion between the various data frequencies. Suppose we want to design a package (a collection of modules) for the uniform handling of various trading strategies and their data.

You can import these packages in your code using the following syntax. You will have access to some in-built packages such as Pandas, NumPy by default when you installed Python. The Python developers community make their codes available for others in the form of packages under the open source license. Importing Python packagesĪs we know Python is an open-source project. Packaging modules in such a way saves the author of different modules from having to worryĪbout each other’s global variable names and the use of dotted module names saves the author of multi-module packages from having to worry about each other’s module names. For example, the module name matplotlib.pyplot designates a submodule named pyplot in a package named matplotlib. It is a way of structuring Python’s module namespace by using 'dotted module names'. Packages can be considered as a collection of modules. Such a file is called a module definitions from a module can be imported into other modules or in the program that we code. To support this, Python has a way to put a code definition in a file and use them in another script or directly in an interactive instance of the interpreter. Also, we may want to use a handy function that we have written in several programs without copying its definition into each program. This is known as writing a script.Īs a program gets longer, we may want it to split it into several small files for easier maintenance. Therefore, in order to write a longer program, we might consider switching to a text editor to prepare an input for the interpreter and running it with that file as an input instead. The definitions that we create(functions and variables) will be lost if we quit the console and enter it again.

We will cover the following concepts in this tutorial

Thus, you can get a simple code for performing simple arithmetic operations or a group of code, called modules and packages, which can help perform data analysis, all on the internet. The beauty of Python is that we have a collection of modules and packages which have been created for a certain purpose and the fact that it is open-source makes it incredibly easy for one individual to build on top of another person’s work and create something useful.

Before we start with the tutorial on how to install Python packages, let us take a step back and understand the role packages play in the Python ecosystem. You need to add this path either to the PYTHONPATH environment variable (I think this would only work when Python is started from your command shell), or add a. Type the command which gdalinfo and note the path to that program (without the gdalinfo name at the end). We already know the folder is in your system path variable, since you are able to execute gdalinfo. You will also want to double-check that Python can find your GDAL installation. So you should probably just try import gdalįrom inside Python, instead of from osgeo import gdal. Did you install GDAL by itself, or did you install OSGEO? You say you installed GDAL, no mention of OSGEO. I am also not sure why you are trying to import gdal as part of OSGEO. I don't know much about your MacOS environment and how you installed Python, so if this does not work, you would need to adjust your environment settings first to make pip work properly.

(On Windows, it would be best to specify the full path the correct pip executable, as they are not named for the Python version like they are for the other systems) If you are using python3 on a Linux or MacOS system, use this command. You do this with the command pip install gdal In addition to installing GDAL, you also need to install the GDAL Python bindings.
