def limit_test(max_char): loop = 1; while not loop > max_char: print(".", end=""); loop += 1
Yes, it’s not possible to write the code this way.
; can only separate “simple” statements, not ones that require a block.
If code like this were allowed, it would be ambiguous: should the
loop +=1 be inside the loop, or outside? Of course you intend it to be inside, but this requires common sense and reasoning - not tools that are accessible to a compiler, which must be absolutely consistent, rule-driven and predictable.
“Put all the code on one line” is not a useful or meaningful goal; it’s a hobbyist’s special challenge. Code is supposed to be written to be understandable, as it will be read far more often than it is written (in particular, by you as the author).
I’m using the Python interpreter and the one-liner is a lot more convenient to do.
Occasionally, but really for anything beyond the most trivial it is more
convenient to just write a tiny
foo.py file (pick your own name) and
Then you can have the file in an editor adjacent to your command line
window, and write nice indented multiline code.
You might be interested in this thread:
in particular this suggestion from it by Jon Crall, which is this form:
python -c "if 1: import pathlib for _ in range(10): print('this is a demo, bear with me') "
By putting an
if 1: on the first line, you can indent all the
following lines nicely on the command line.
