How to slice a string via code points in Rust
fn main() {
let text = "Super🐍Snake";
let text_slice = &text.chars().collect::<Vec<_>>()[5..=10];
for character in text_slice {
println!("{}", character);

Examples of some Rust Crates that mimic some common Python data structures
use counter::Counter;
use defaultmap::DefaultHashMap;
fn counter_example() {
let counter = "Hello, world!".chars().collect::<Counter<_>>();
for (item, count) in counter.most_common() {
println!("{}: {}", item, count);

A program that shuffles the characters of each word in a text file, while preserving the position of punctuation
import random
def shuffle_word(word):
shufflable_characters = [character for character in word if character.isalnum()]
random.shuffle(shufflable_characters)
word = [shufflable_characters.pop(0) if character.isalnum() else character for character in word]
word = "".join(word)
# Sanity check to ensure we've used the exact same number of letters as we initially collected
assert len(shufflable_characters) == 0

A few examples illustrating a few ways to iterate over `Results` in Rust
fn main() {
let items: [Result<i32, &str>; 4] = [Ok(1), Ok(2), Err("Missing Value"), Ok(3)];
// 1
let items_result: Result<Vec<_>, _> = items.into_iter().collect();
match items_result {
Ok(items) => {
for item in items {
println!("{}", item);

A function that uses a Python Counter to print a visual summary of the occurrences of integers in a list
from collections import Counter
from random import randint
def visualize(numbers):
counter = Counter(numbers)
max_number_length = len(str(max(numbers)))
for number, count in counter.most_common():
padded_number = str(number).rjust(max_number_length, "0")
