IDLE main entry point Run IDLE as python -m idlelib So with python -m idlelib script_to_edit you will be able to open and edit the script with idle. I haven't checked with previous versions but it could be the same comand Running Python script from IDLE on Windows 7 64 bit. 3. start the python IDLE from a python script. 5. As there is no more IDLE2 for Python2, I installed sudo apt-get install idle But idle-python3.7 was installed !! In the main menue editor I find Python 2 (IDLE) and Python 3 (IDLE) . But if I open Python 2 (IDLE), a IDLE version 3.7.3 is opening. (If I open Python 3 (IDLE) I get the same IDLE version 3.7.3)

Python 3 Notes: Trying out Python IDLE for the First Time

Srfpalaunread,Nov 30, 2017, 12:30:51 PM11/30/17to PyScripterA very simple wxPython example runs cleanly in Idle 2.7.12 under Win10But when I try the same App in PyScripter the ModuleNotFoundError: No module named 'wx' error is generatedCode follows:def main(): passif __name__ == '__main__': main()import wxprint ("New wxPython3.0-py27 Install Pass 04 ")app = wx.App(redirect=True)top = wx.Frame(None, title="Hello World Pass 04", size=(300,200))top.Show()app.MainLoop()# ------------------ End of Code ----------------Apparently PyScripter needs something that IDLE doesn'tMust be missing a setting. Any ideas are appreciated.BobKiriakos Vlahosunread,Nov 30, 2017, 2:31:36 PM11/30/17to [email protected] Bob,PyScripter does not require anything more than IDLE. Probably PyScripter is using a different version of python than Idle than PyScripter and wx is not installed in that version of Python.When you start either IDLE or PyScripter you see something like this.Python 3.6.3 (v3.6.3:2c5fed8, Oct 3 2017, 18:11:49) [MSC v.1900 64 bit (AMD64)] on win32Do the versions in PyScripter and IDLE much?You can use PyScripter with different versions of Python using the provided shortcuts (e.g. PyScripter for Python x.x) or by using command-line options such as --PYTHON27RegardsKiriakosBob Palankunread,Dec 2, 2017, 1:55:28 PM12/2/17to [email protected] for your reply.Using IDLE I see:Python 2.7.12 (v2.7.12:d33e0cf91556, Jun 27 2016, 15:19:22)[MSC v.1500 32 bit (Intel)] on win32Python version 2.7.12 and IDLE Ver 2.7.12Using Pyscripter The Python Interpreter dialog shows: Python 3.6.0 (v3.6.0:41df79263a11, Dec 23 2016, 08:06:12) [MSC v.1900 64 bit (AMD64)] on win32.Before I do any guessing, I'll await your reply.Thanks in advance for your attention.BobKiriakos Vlahosunread,Dec 2, 2017, 4:52:31 PM12/2/17to [email protected] Bob,As the note at the download page says:"The 64-bit version of PyScripter (x64) works only on 64-bit Windows **and**with 64-bit versions of Python. The 32-bit version of PyScripter works on both32-bit and 64-bit Windows with the 32-bit versions of Python.".Apparently in your machine you have at least two versions of Python installed. A 32bit version of Python 2.7 used by IDLE and a 64 bit version of python 3.6 picked up by the 64-bit version of PyScripter you are using.To work with the 32bit version of python from PyScripter you need to download and install the 32-bit version of PyScripter. This can be installed side-by-side with the 64 bit version. You then use the PyScripter created shortcuts of the 32bit PyScripter (e.g. PyScripter for Python 2.7) to load 32bit Python 2.7.Hope this helps.RegardsKiriakos Bob Palankunread,Dec 3, 2017, 2:02:36 PM12/3/17to [email protected] job and hanks again. Up and running just fine !Bob

'SyntaxError: invalid syntax' in python 3 IDLE - Stack

It’s a good idea to check the version of Python your system currently has. macOS often comes with an older version of Python (Python 2.x) pre-installed.To check your system’s Python version, open the Terminal app (you can find it using Spotlight search or under Applications > Utilities) and type the following command:python --versionPress Enter, and you’ll see the version number displayed in the output like this:Python 2.7.xIf your system has Python 3.x installed, you can check its version by running the following command:python3 --versionIf you’re satisfied with the installed version of Python 3.x, you can skip the remaining steps. If Python 3.x is not installed or you want to install a newer version, proceed to the next step.Step 2: Visit the Python websiteGo to the official Python website to access the download page for the latest version of Python for macOS.Current Python releases for macOS.Step 3: Download the macOS installerOn the download page, you’ll find the macOS installer package (.pkg file) for the most recent Python release. Download the installer to your computer.Step 4: Run the installer and follow the instructionsLocate the downloaded installer file (usually in your Downloads folder) and double-click on it to run the installation process.Python installer for macOS.Proceed through the installation steps by agreeing to the software license agreement, choosing the installation location (we recommend using the default location), and entering your administrator password when prompted.Step 5: Verify Python and IDLE are installed correctlyOnce the installation process is completed, a folder will open on your desktop. Click IDLE in this folder.Following installation, open IDLE in macOS.IDLE is the independent development environment that comes with Python. Once opened, you should see a Python shell automatically.Python shell in IDLE.You can verify it’s working correctly by typing in a print command as follows:print(‘Test message’)Press Enter and the text “Test message” should now appear on the next line in IDLE.Step 6: Verify the installation with terminalYou can verify installation via the Terminal as well. Open the Terminal app and type the following command:python3 --versionPress Enter, and you should see the version of Python you just installed displayed.This confirms that Python has been successfully installed on your Mac.How to install Python on LinuxThe process of installing Python on a Linux operating system is a bit different than the processes for Windows and MacOS. Many Linux distributions come with Python pre-installed, but it might not be the latest version.To install or update Python on your Linux machine, follow these steps:Check for pre-installed PythonInstall via Package ManagerDownload the latest version of PythonCompile from source (optional)Configure the script and complete the build processVerify installationStep 1: Check for pre-installed PythonOpen a terminal window and type the following command to check if Python is already installed

In this section.The Python script resides in an IDLE window. IDLE downloads automatically when you install Python from Python.org. IDLE is one of several developer environments for writing, saving, and running Python scripts. The script’s filename (get_fundamental_data.py) appears at the top of the screen shot below. SQL Server professionals may find it useful to think of IDLE for Python code in the same way that think of SSMS for T-SQL code. Comment lines in the script segment the code into seven steps. Each step starts with a marker for a comment line (#).The first step includes two library declarations that contain objects with methods used within the script. It also includes a declaration for a Python package.The yfinance library is an external library associated with an alias name (yf). One method in this library can populate a Python dictionary object with fundamental data from Yahoo Finance. Yfinance is called an external library because it is supported by a third party that is different from Python.org.The os library is an internal Python library. This tip uses the os library to manage the current working directory. There is no need to use an alias when referring to methods from an internal Python object.The JSON package appears somewhat similar in functionality to an internal Python library. Within this tip, the JSON package supports the conversion of a Python dictionary object to a string with JSON formatted data. This reference provides especially clear documentation on the Python JSON package.The second step invokes the Ticker method in the yf library; the name for this method is case sensitive. The method returns a ticker object.The argument for the Ticker method is a symbol that is not case sensitive.The return value from the method is not case sensitive either.In the Python script for this tip,the symbol name.
