These are some tricks in python that should help with speed-based programming competitions, like ProgComp.
enumerate is usually used when you want to iterate over a list, and have easy access to both the value and the index.
for index, value in enumerate(my_list):
| import random | |
| import numbers | |
| from timeit import timeit | |
| data = [0] * 1000000 + [0.0] * 1000000 + [(0, 0)] * 1000000 + [[0, 0]] * 1000000 | |
| random.shuffle(data) | |
| def is_int_float(x): | |
| return isinstance(x, int) or isinstance(x, float) |

| Note that all the ranges in this code are [inclusive, exclusive) | |

| Befunge interpereter, in one large file. | |
| Code taken from this repo: https://github.com/programble/befungeec | |
| It's been smooshed into one file and modified somewhat. | |
| Improvements: | |
| - Shows a special symbols for unprintable characters in debug mode. | |
| - Shows a help message when run with no arguments, rather than crashing. |
