Checking Vulnerabilities in Your Python Code with Bandit
As developers, we're encouraged from the start of the journey to write clean code. Equally as important, but less talked about is writing and using secure code. In Python projects, we typically install modules and third-party packages to avoid developing solutions that already exist. However, this common practice is why...
How to Install Pip on Windows
Package managers are tools commonly created for programming languages that make the setup and management of third-party packages easier. Pip is the preferred package manager in Python for both the native Pip modules and the ones installed inside the virtual environments. When Pip is invoked, it automatically crawls against the...
