Python start-up file

.pythonstartup.py

# Python start-up file
# --------------------
# Ensure a PYTHONSTARTUP environment variable points to the location of this file.
# See https://docs.python.org/3/using/cmdline.html#envvar-PYTHONSTARTUP

# Always have pp available
from pprint import pprint as pp

# Pre-emptively import datetime as I use it a lot.
import datetime

# Import rich (https://rich.readthedocs.io/en/latest/introduction.html) to get prettier
# output in the REPL.
try:
    from rich import pretty as __pretty, inspect as __inspect
except ImportError:
    # rich won't necessarily be installed in all environments
    __inspect = pp
else:
    # Ensure printing is pretty by default.
    __pretty.install()

def inspect(*args, **kwargs):
    # Custom rich.inspect wrapper to ensure methods are inspected by default.
    if "methods" not in kwargs:
        kwargs["methods"] = True
    __inspect(*args, **kwargs)


# Print the commands that have been imported as a memory jogger.
print(">>> from pprint import pprint as pp")
print(">>> from rich import inspect")
print(">>> import datetime")

# Define aliases for true, false and null so JSON can be pasted straight in.
true = True
false = False
null = None

I don't get

Maybe because I am amateur

This is pretty awesome! I was completely unaware of PYTHONSTARTUP.
