            The core of extensible programming is defining functions. Python allows mandatory and optional arguments, keyword arguments, and even arbitrary argument lists. Whether you're new to programming or an experienced developer, it's easy to learn and use Python. Python can be easy to pick up whether you're a first-time programmer or you're experienced with other languages. The following pages are a useful first step to get on your way to writing programs with Python! The community hosts conferences and meetups to collaborate on code, and much more. Python's documentation will help you along the way, and the mailing lists will keep you in touch. The Python Package Index (PyPI) hosts thousands of third-party modules for Python. Both Python's standard library and the community-contributed modules allow for endless possibilities.

            Add charts to emails, reports, and anywhere else. Over 3 billion charts are rendered for users around the world. Generate chart images with a simple, open API. Our chart API generates chart images, QR codes, and more. We're built on Chart.js, the most popular open-source charting library. We'll render any Chart.js configuration. Start by putting your Chart.js definition in a URL. Let's get creative! You can use all static customization options available in Chart.js. Visit our chart gallery to see different chart types and plugins: bar charts, line graphs, pie charts, and much more. QuickChart easily integrates with many no-code tools. Use our no-code chart maker to create custom chart templates that you can embed dynamically in spreadsheets, Airtable, Bubble, AppSheet, Thunkable, and many other no-code tools. Rendering at scale is difficult and resource intensive. We've put a lot of working into taking care of the most difficult parts so you can focus on building your application.

            Tcl is a very simple programming language. If you have programmed before, you can learn enough to write interesting Tcl programs within a few hours. This page provides a quick overview of the main features of Tcl. After reading this you'll probably be able to start writing simple Tcl scripts on your own; however, we recommend that you consult one of the many available Tcl books for more complete information. Each Tcl command consists of one or more words separated by spaces. In this example there are four words: expr, 20, +, and 10. The first word is the name of a command and the other words are arguments to that command. All Tcl commands consist of words, but different commands treat their arguments differently. The expr command treats all of its arguments together as an arithmetic expression, computes the result of that expression, and returns the result as a string. In the expr command the division into words isn't significant.
