Python Tip #186 (of 365): Use the errors argument when reading files with encoding issues. 🧵 Reading a file with the wrong encoding either raises a UnicodeDecodeError or silently produces mojibake (garbled text). The "errors" argument provides control over the first case. #Python #DailyPythonTip

Python Tip #185 (of 365): Normalize Unicode strings before comparing them. 🧵 Some Unicode characters can be written in more than one way. Python's == won't consider them equal even if they look identical. Use unicodedata.normalize() to fix this. #Python #DailyPythonTip

I'm not following the World Cup, but I am enjoying seeing country names and thinking "I know where that is!" I didn't know where Cabo Verde was before making whereabouts.earth. Note: Whereabouts goes (mostly) by UN membership to judge "what's a country", so no England, Scotland, or Curaçao.

The reversed() function works on all sequences, but it also works on some other iterables, like dictionaries Read more 👉 https://trey.io/ur7l4g #Python

Python Tip #184 (of 365): Always specify the encoding when opening text files. 🧵 If you don't, Python picks a platform-dependent default, and you may read garbled text or get an error. #Python #DailyPythonTip

Python Tip #183 (of 365): Wrap text to a fixed width with textwrap.wrap. 🧵 Need to hard-wrap a long string to 70 (or any number of) characters? Use the wrap or fill functions from Python's textwrap module. #Python #DailyPythonTip

Python Tip #182 (of 365): Use textwrap.dedent() to unindent multi-line strings. 🧵 A multi-line string inside an indented function inherits that indentation. textwrap.dedent() strips the common leading whitespace so your output looks right. #Python #DailyPythonTip

Python Tip #181 (of 365): Don't use Python's "str.title()" method. 🧵 It capitalizes letters after apostrophes, turning "don't" into "Don'T". #Python #DailyPythonTip

Python Tip #179 (of 365): Use history & paste mode in the new REPL. 🧵 F2 enters history: previous code is shown WITHOUT >>> prompts, so you can copy just the code. F3 enters paste mode: Enter won't accidentally run your code block while you're editing it. #Python #DailyPythonTip

Spreading misinformation is wrong. It does not matter whether the sentiment of the misinformation is one that aligns with your beliefs about the world or whether it moved you. Spreading misinformation is wrong.

Python Tip #178 (of 365): Hack your Python REPL 🧵 The REPL in Python 3.14 includes syntax highlighting. It's pretty great! But did you know that you can customize the color scheme it uses? #Python #DailyPythonTip

Python Tip #177 (of 365): Learn your REPL's keyboard shortcuts. 🧵 This is especially useful in Python 3.13+ because there are even more useful shortcuts. The most useful: Ctrl+P and Ctrl+N navigate between blocks (not lines). No more pressing Up many many times! #Python #DailyPythonTip

Python Tip #176 (of 365): Customize your REPL with PYTHONSTARTUP. 🧵 If you set the PYTHONSTARTUP environment variable to point to a file containing Python code: export PYTHONSTARTUP=~/.pythonstartup.py Python will run that file at the start of each new Python REPL. #Python #DailyPythonTip

Python Tip #175 (of 365): Pass "-i" to Python to drop into a REPL after your script runs. 🧵 $ python -i fibonacci.‍py >>> nth_fibonacci(10) 55 You'll have access to everything the script defined. Passing "-i" is like copy-pasting your entire script into a Python REPL. #Python #DailyPythonTip

Python Tip #174 (of 365): Python modules are cached. 🧵 The first time each Python process imports a module, it caches it in sys.modules. The second time you import the same module, Python returns the cached module object without re-running the module code. #Python #DailyPythonTip

Python Tip #171 (of 365): Customize PDB with a ~/.pdbrc file. 🧵 You can make a ~/.pdbrc file to add your own commands to the Python debugger. This ISN'T a Python file, so it's a bit tricky to create, but spending a few minutes making one is well worth it. #Python #DailyPythonTip
