25 Useful Coding Tips for Python Beginners

I created a long video on youtube pertaining to 25 tips to help you write better code in Python, this can help you in a professional setting, or in coding interviews. These tips include ways to improve the readability/maintainability of your code, improve efficiency, and learn aspects of the Python language you may have never heard of!

There are many tips which I summarize here:

  • Organize Imports Properly
  • Learn to Use PDB
  • Use the new Match/Case Statements
  • Learn about the Bisect Library
  • Learn about the Walrus Operator
  • Know when to use Enumerate over Range
  • Utilize Numpy for Efficiency
  • cProfile for finding Bottlenecks
  • Catch-all Unpacking to improve readability
  • Prefer f-strings over other string formatting methods
  • Naming Variables properly
  • Know when to use Generators over Lists
  • .get() Method to help with dictionaries
  • Specific Exceptions as opposed to broad exceptions
  • .zip() Method when iterating over multiple lists can help
  • Loops with Else Statements, not a very well-known feature in Python
  • Write Docstrings for complicated functions in practice
  • Be cautious with Python Dict Order
  • List Comprehension better practice
  • Use Dictionary Comprehension, a lot of people do not do this for some reason
  • Avoid one-line if/loops (seen a lot in hackerrank and leetcode)
  • Don’t check for empty containers/sequences, use "if not" instead
  • Split Long Lines of more than 79 chars
  • Add new line to the end of a file always in accordance with pep8
  • … Practice these points in your projects and share with teammates in code reviews :)

Would really appreciate anyone watching the video. I definitely think it can help new beginners. If you like such content please subscribe to the channel it would mean a lot!
