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. First, we’ll show how to install matplotlib, which is a package that shows plots of mathematical functions. 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.
