Two other functions that you might find useful (that require you to use lists) are:Įasy.get_choice("Message to user", "Window Title", ), which returns a single choice from the list (or None if cancelled)Įasy.get_list_of_choices("Window title", ), which returns a list of selected items (or an empty list if cancelled) Returns a True or False (or None if cancelled) For quick reference, here are a few of them (each of the following assumes you have already called import easygui_qt as easy): You may want to look in the appendices for the EasyGUI_Qt Reference for a more comprehensive list of what is available. There are many more methods you can use with easygui_qt. show_message ( "Are you just saying that?" ) else : easy. show_message ( "I'll take that as a good sine" ) elif favourite = "Computer Science" : easy. show_message ( "To be or not to be: that is the question." ) elif favourite = "Math" : easy. get_choice ( "What is your fav?", "Pick Subject", subjects ) if favourite = "English" : easy. # import the module to allow GUI interaction import easygui_qt as easy subjects = favourite = easy. Now type in cs20-easygui into the Search box (be sure to spell it exactly). In Thonny, open Tools -> Manage packages….

When using Python outside Reeborg, if you’d like to get user input through a graphical pop-up box instead of just through the console, we can just install a module cs20-easygui. For many Python modules, this is equivalent to saying, “Look into the library.py file, and find a function called turn_right()”.Īnother method of importing the library allows us give the module a nickname that is faster to type.
#Thonny wall code#
You can think of this code as saying “Look into the library, and find something called turn_right()”. However, it was also possible to import the library as follows: In Reeborg, we would often import that code using from library import turn_right, so that we could simply call the turn_right() function in the same way that we could call turn_left(). When we were programming Reeborg, we would often put functions into the library tab, like this: It gives us the ability to use extra functionality that another programmer has created. You can think of a module as being similar to the library tab that we used in Reeborg. One of the great things about Thonny is how easy it is to add additional modules to the standard Python installation. Select Tools → Manage packages for even easier installation of 3rd party packages.Print("Wow! Already " + age + " years old!")Ħ.2.

PATH and conflicts with other Python interpreters are taken care of by Thonny. Select Tools → Open system shell to install extra packages or learn to handle Python on the command line. Students can explore APIs with the help of code completion.īeginner friendly system shell.

Variables are initially presented according to the simplified model (name → value), but you can switch to a more realistic model (name → address/id → value).Ĭode completion. Local and global names are visually distinguished Local variables are visually distinguished from globals. Highlighting variable occurrences reminds you that the same name doesn’t always mean the same variable and helps to spot typos. Thonny’s editor makes these easy to spot.Įxplains scopes. Unclosed quotes and parentheses are the most common beginners’ syntax errors. Good understanding of how function calls work is especially important for understanding recursion. Stepping into a function call opens a new window with separate local variables table and code pointer. You can think of this light-blue box as a piece of paper where Python replaces subexpressions with their values, piece-by-piece.įaithful representation of function calls. If you use small steps, then you can even see how Python evaluates your expressions. Steps follow program structure, not just code lines. Press F6 for a big step and F7 for a small step. Just press Ctrl+F5 instead of F5, and you can run your programs step-by-step, no breakpoints needed. Once you’re done with hello-worlds, select View → Variables and see how your programs and shell commands affect Python variables. (You can also use a separate Python installation, if necessary.) The initial user interface is stripped of all features that may distract beginners. Thonny comes with Python 3.7 built-in, so just one simple installer is needed, and you’re ready to learn to program. Thonny is an Open Source Python IDE for beginners.Įasy to get started.
