Python Tip #4 (of 365):
If you're debugging with print() calls, use a self-documenting expression in an f-string.
>>> n = 256
>>> print(f"DEBUGGING {n**2=}")
DEBUGGING n**2=65536
Note the replacement field with = at the end.
Without = in the replacement field, the string would contain only the expression result:
>>> print(f"DEBUGGING {n**2}")
DEBUGGING 65536
With the =, the string contains both the replacement field expression and the expression result.
