❓ Что выведет следующий код на Python (модуль statistics)?


import statistics as stats
import math

data = [1, 2, 2, float('nan'), 3, 4]

print("Mean:", stats.mean(data))
print("Median:", stats.median(data))
print("Mode:", stats.mode(data))

🔢 Варианты ответа:

A)


Median: 2.5
Mode: 2

B)


Median: 2.5
Mode: 2

C)ValueError: nan is not a valid number

D)


Median: nan
Mode: 2

✅ Правильный ответ: C

💡 Почему?
- Модуль

statistics

не умеет работать с

NaN

.
-

stats.mean()

и

stats.median()

вызовут

StatisticsError

или

ValueError

.
- В отличие от

numpy.nanmean

, здесь всё падает.
📌 Подвох — в

float('nan')

в списке.

For Oleksandra Tsekhanovska, head of the Hybrid Warfare Analytical Group at the Kyiv-based Ukraine Crisis Media Center, the effects are both near- and far-reaching. The account, "War on Fakes," was created on February 24, the same day Russian President Vladimir Putin announced a "special military operation" and troops began invading Ukraine. The page is rife with disinformation, according to The Atlantic Council's Digital Forensic Research Lab, which studies digital extremism and published a report examining the channel. False news often spreads via public groups, or chats, with potentially fatal effects. Telegram, which does little policing of its content, has also became a hub for Russian propaganda and misinformation. Many pro-Kremlin channels have become popular, alongside accounts of journalists and other independent observers. The fake Zelenskiy account reached 20,000 followers on Telegram before it was shut down, a remedial action that experts say is all too rare.
