Python fa piovere

Beh di cosa vi stupite, Python può farlo. 

Il codice non è mio, ma non ricordo esattamente la fonte, ma insomma provatelo e ditemi se non è divertentissimo.

from collections import deque
import random
import shutil
from time import sleep
 

TERMINAL_WIDTH, TERMINAL_HEIGHT = shutil.get_terminal_size()
RAIN_DENSITY = 0.15
EMPTY_LINE = " " * TERMINAL_WIDTH

lines = deque([EMPTY_LINE for _ in range(TERMINAL_HEIGHT)], maxlen=TERMINAL_HEIGHT)

def build_next_line(source):
    next_row = ["|" if char == "v" else " " for char in source]
    for idx, _ in enumerate(next_row):
        if random.random() < RAIN_DENSITY:
             next_row[idx] = "v"
    return "".join(next_row)

while True:
    new_row = build_next_line(lines[0])
    lines.appendleft(new_row)
    for row in lines:
        print(row)
    sleep(0.05)
