Python Software Foundation 2020 Fundraiser
“COVID-19 has changed all aspects of our lives and is reshaping our future. Nonprofits like the PSF are having to rebuild. With PyCon 2020 and 2021 happening virtually, the PSF is faced with potentially losing $1.2 million USD of expected revenue for those two years. This fundraiser is critically important and the money raised will help the PSF support the tools and initiatives that Pythonistas use everyday.”

How Python Manages Memory and Creating Arrays With np.linspace
Have you wondered how Python manages memory? How are your variables stored in memory, and when do they get deleted? This week on the show, David Amos is here, and he has brought another batch of PyCoder’s Weekly articles and projects. Along with the Real Python article on Python memory management, we also talk about another article about creating even and non-even spaced arrays in Python with np.linspace.
