Therefore, let's focus on installing it on our machine and testing to see if we can get a basic Flask application running. We already know what Flask is and its capabilities. If we cannot find Pip for Python 3 on our machine, we can follow the instructions here to install Pip. If the command above produces an output similar to pip 9.0. Therefore, let's check if we need to install pip separately or already have it. 9 or Python 3 >= 3.4, installing Python through apt on Ubuntu doesn't install pip. While the official installation page states that pip comes installed if we're using Python 2 >= 2.7. Pip is the recommended tool for installing Python packages. If this command produces the correct output, we must replace all commands throughout the article to use python3 instead of just python. If we get "Python 2" instead, we can try issuing python3 -version. What is important is that you are running at least Python 3.7 or newer. Note that the command above might produce a different output when we have a different Python version. If we are running Windows, we will probably need to install Python 3, as this operating system does not ship with any version.Īfter installing Python 3 on our machine, we can check that we have everything set up as expected by running the following command: python -version If we are using some recent version of a popular Linux distribution (like Ubuntu) or macOS, we might already have Python 3 installed on our computer. We will need to install Python 3, Pip (Python Package Index), and Flask. Bootstrapping a Flask Applicationįirst and foremost, we will need to install some dependencies on our development machine. However, as it is a newer framework, many more resources and libraries are compatible with frameworks like Django and Flask but not with FastAPI.īeing lightweight, easy to adopt, well-documented, and popular, Flask is a good option for developing RESTful APIs. Lastly, Flask has extensive documentation that addresses everything developers need to start.įastAPI follows a similar "micro" approach to Flask, though it provides more tools like automatic Swagger UI and is an excellent choice for APIs. Flask won't make many decisions for us, such as what database to use or what template engine to choose. Flask developers call it a microframework, where micro ( as explained here) means that the goal is to keep the core simple but extensible. Flask applications are known for being lightweight, mainly compared to their Django counterparts. From the ground up, Flask was built with scalability and simplicity. On GitHub, Flask has almost 60k stars, ~650 contributors, ~23 releases, and nearly 15k forks.Įven though Django is older and has a slightly more extensive community, Flask has its strengths. This elegant framework built for high-performance and fast-to-code APIs is not one to miss.įlask, although less popular, is not far behind. On GitHub, this framework has around 66k stars, 2.2k contributors, ~ 350 releases, and more than 25k forks.įastAPI is growing at high speed, with 48k stars on Github, 370 contributors, and more than 3.9k forks. Django is older, more mature, and a little bit more popular. When it comes to web development on Python, there are three predominant frameworks: Django, Flask, and a relatively new player FastAPI. Besides the tremendous support provided by the overall community, the Python Software Foundation also provides excellent documentation, where new adopters can learn its essence fast. More and more open source libraries are being released to address many different subjects, like Artificial Intelligence, Machine Learning, and web development. The huge community forming around Python is improving every aspect of the language. On GitHub, the language also shows signs of mass adoption, occupying the second position among the top programming languages in 2021. As StackOverflow recently analyzed, Python is one of the fastest-growing programming languages, having surpassed even Java in the number of questions asked on the platform. Nowadays, choosing Python to develop applications is becoming a very popular choice. Serializing and Deserializing Objects with Marshmallow.Peek - This returns the top data value of the stackĪ program that implements a stack using array is given as follows.This article is divided into the following sections: Pop - This removes the data value on top of the stack Push - This adds a data value to the top of the stack. Some of the principle operations in the stack are − the element that is pushed at the end is popped out first. A stack is an abstract data structure that contains a collection of elements.
