howdoi in Python:

Python howdoi is a command-line tool that is extremely useful for newcomers. We may use this tool to find answers to numerous programming operations, such as printing a list in Python, putting comments, and so on. We can perform all of this from the command line. Python howdoi basically collects data from the top answers from stack overflow and tells us what to do. Because it scrapes data from the internet, we must have an active internet connection to use it.

howdoi will answer all of your programming and coding questions. For example, obtaining syntactic help, looking for libraries for a certain purpose, resolving issues, using pre-defined functions and their applications, and so on.
