🖥 Циклы for в Python работают иначе, чем во многих других языках программирования

Правила, описывающие работу циклов for, определяются так называемым протоколом итератора. Благодаря этому цикл for можно реализовать через while:

def print_each(iterable):
iterator = iter(iterable)
while True:
try:
item = next(iterator)
except StopIteration:
break
else:
print(item)


Код выше эквивалентен следующему циклу:
def print_each(iterable):
for item in iterable:
print(item)

When choosing the right name for your Telegram channel, use the language of your target audience. The name must sum up the essence of your channel in 1-3 words. If you’re planning to expand your Telegram audience, it makes sense to incorporate keywords into your name. Over 33,000 people sent out over 1,000 doxxing messages in the group. Although the administrators tried to delete all of the messages, the posting speed was far too much for them to keep up. Public channels are public to the internet, regardless of whether or not they are subscribed. A public channel is displayed in search results and has a short address (link). A few years ago, you had to use a special bot to run a poll on Telegram. Now you can easily do that yourself in two clicks. Hit the Menu icon and select “Create Poll.” Write your question and add up to 10 options. Running polls is a powerful strategy for getting feedback from your audience. If you’re considering the possibility of modifying your channel in any way, be sure to ask your subscribers’ opinions first.
