IDLE || Python || Python GUI

An alternative to the command line is Python's Integrated Development and Learning Environment (IDLE). As its name suggests, IDLE is excellent for learning Python or writing new code. On Windows, the Python interpreter is already installed, but on other operating systems, you might have to install it using your package manager.

IDLE's primary goals are:

• Multi-window text editor with smart indent, autocomplete, and syntax highlighting
• Highlighting of syntax in the Python shell
• integrated debugger with call stack visibility, persistent breakpoints, and stepping
• Python's automatic indentation is helpful for newcomers learning the syntax.
• Python programmes may be saved as.py files, launched, and edited using IDLE at any time.

Press F5 or execute Python Shell in IDLE to start an interpreter. Since code is interpreted as the user writes it, using IDLE might provide new users with a better learning experience.

Be aware that there are many options available. For instance, have a look at this topic or this list.

Troubleshooting

Windows

Python is the default command if you're using Windows. The most frequent cause of a "python" problem is that Python's location is not mentioned in your system's PATH environment setting.. You may do this by choosing "Properties" from the context menu when you right-click on "My Computer" or by going to "System" in the "Control Panel". After selecting "Advanced system options," select "Environment Variables..." The Python installation directory and the Script folder (often C:Python27;C:Python27Scripts) to be added to the PATH variable. This calls for administrative rights and can necessitate a restart.

Renaming one of the python.exe files may help if you're running multiple Python versions on the same computer. For instance, if a version is named python27.exe, the Python command for that version will be python27.

Additionally, you may utilise the Python Launcher for Windows, which is pre-installed and accessible through the installation. By using py -[x.y] rather than python[x.y], you may choose the version of Python to execute. The most recent versions of Python 2 and Python 3 may be used by executing scripts with py -2 and py -3, respectively.

Debian/Ubuntu/MacOS

This section presupposes that the PATH environment variable has been updated to include the location of the Python executable.

Open the terminal in Debian, Ubuntu, or Mac OS and enter python for Python 2.x or python3 for Python.

3.x. To find out which Python interpreter will be used, type which python.

Arch Linux

Use python or python3 for Python 3.x and python2 for Python 2.x as Python 3 is the default on Arch Linux (and its offspring).

Other systems

Sometimes, Python 3 is tied to python rather than Python 3. Python 2 should be used on these platforms where
