horrifying python code, bad for screen reader

Python lets you do interesting things in f-strings

you can put an f-string inside of an f-string

>>> a = {"jkl": 123}
>>> b = {"0x7b": "beep"}
>>> f"{b[f"{hex(a["jkl"])}"]}"
'beep'

and you’re not just limited to that. your string can actually take user input and import all on it’s own!

>>> f"{"".join(__import__("importlib").import_module("string").ascii_lowercase[int(i)] for i in input(">").split(' '))}"
>1 4 4 15
'beep'

we all know the classic construct

if __name__ == "__main__":
    main()

but that’s boring and unoriginal. next time you write a script, switch it up!

f"{__name__ == '__main__' and main()}"

everyone reading will be very impressed by your clever thinking and enjoy a fun little puzzle!

brie@parmesan ~/c/cheese-paper (main)> cat scripts/crimes.py
def main():
    print("beep")

f"{__name__ == '__main__' and main()}"
brie@parmesan ~/c/cheese-paper (main)> python scripts/crimes.py 
beep

you can also use this in bash. it’s really helpful when you want a simple one liner but still keeping nice output formatting!

$ python -c 'print(f"{__import__("importlib").import_module("os").get_terminal_size()}")'
os.terminal_size(columns=148, lines=22)

@brie couldn’t this serve as a doc string for the module too?
