If you try this on the plotting program above, you’ll probably get an error complaining that matplotlib doesn’t exist. (Click Ctrl+S or the Save icon in the toolbar.) You can then run your project to see what happens. Make sure you save the change before running your program. On the General tab, select the Python interpreter you want from the drop down menu at the bottom. You’ll then get window with tabs named ‘General’, ‘Debug’, ‘Publish’ and ‘Test’ on the left. On Visual Studio’s Project menu, select Project> properties, where is whatever you’ve called your project.

Let’s say you’ve decided to install Python version 2.7 alongside the default Python 3.7 and you want to test your program using 2.7. You’ll need administrator privileges to do this. Select one or more of these versions and then click the ‘Install’ button at the lower right. In the dialog box that appears, select ‘Python installation’ on the left, and you’ll see a list of available Python versions that you can install, along with those that are already installed.
To do this, click on ‘Add Environment…’ in the Python Environments panel shown above.

If you want to test your code in a different version than the one in which it was written, you can install a different version of Python in Visual Studio. One of the annoying things about Python is that different versions support different features and, sometimes, actually break code that was written in an earlier version. When it’s done, you can then run the above program and, hopefully, see this output: You should then see the Package Manager Console giving reports of progress in the installation process (which might take a couple of minutes so be patient). Type ‘matplotlib’ into this box and you should see a list of options containing this term. Select this, and you should then get a box with the text ‘Search PyPl and installed packages’. You should see an option called ‘Packages’, as shown: Next, click on the drop down menu labelled Overview. If you installed Visual Studio with just the default Python environment, you’ll probably have only Python 3.7 installed. This should open a panel on the right that looks like this:ĭon’t worry if your panel doesn’t look exactly like this the Python environments listed depend on how many you have installed. In Visual Studio’s View menu, select View>Other windows>Python environments. If you don’t have matplotlib installed, the editor will underline the terms numpy, matplotlib and pyplot in lines 2 and 3 and complain that they are unknown. The final argument in the np.arange() function specifies the colour of the plot, using one of the standard HTML colour names. This code should show a plot of the function for between 0.01 (to avoid dividing by zero) up to 1800 degrees, with a spacing between plot points of 12 degrees. X = np.arange(0.01, radians(1800), radians(12))ĭon’t worry about the details of the code for now we’ll cover this in future posts.
Import numpy as np # installed with matplotlib Enter the following code into the main code window (usually at the upper left): from math import radians Installing a new Python packageĬreate a new Python project in Visual Studio.
Python in visual studio how to#
First, we’ll show how to install matplotlib, which is a package that shows plots of mathematical functions. Note: Do remember to configure the pythonPath in launch.json as well.Although Visual Studio 2019 comes with a complete basic Python installation, there are many third-party packages that you may wish to use, so it’s useful to know how to install these. Option 1: Ensure the path to the python interpreter is set in python.pythonPath as defined previously. There are two approaches to to getting this extension working in a particular Virtual Environment. "python.pythonPath": "c:/python27/python.exe" If a specific version is to be used, then configure the path to the python interpreter in the User or Workspace Settings file (settings.json) as follows.Įnsure to specify the fully qualified name of the python executable (Mac and Linux supported). The standard interpreter used is the first “python” interpreter encountered in the current path. The same python interpreter is used for intellisense, autocomplete, linting, formatting, etc. Python Version used for Intellisense, Autocomplete, Linting, Formatting, etc If the interpreter you are looking for isn’t listed here, then please proceed to the next section and enter it manually. Selecting an interpreterĬonfiguring the extension to use a particular interpreter is now easy.Īll you now need to do is make use of the command Select Workspace Interpreter from the command palette and select an interpreter from the list. You could always change this by specifying the path to the interpreter in the user or worksapce settings.
By default the extension uses the Python interpreter available in the current path.
