Скорее всего уже слышали, что складывать строки через + это плохая практика. Падение производительности, и всё такое. Без лишних слов, давайте измерять:
from timeit import timeit
def t1():
# складываем 10 строк через + из переменной
t = 'text'
for _ in range(1000):
s = t + t + t + t + t + t + t + t + t
def t2():
# склеиваем список строк через метод join
arr = ['text'] * 10
for _ in range(1000):
s = ''.join(arr)
def t3():
# складываем через + но не из переменной а непосредственно инлайн объекты
for _ in range(1000):
s = 'text' + 'text' + 'text' + ... # всего 10 раз
Теперь каждую строку склейки запустим по 10М раз
>>> timeit(t1, number=10000)
0.21951690399964718
>>> timeit(t2, number=10000)
1.4978306379998685
>>> timeit(t3, number=10000)
0.2213820789993406
Хм, а нам говорили что через "+" это плохо и медленно ))) 😁
Тут стоит учитывать, что речь идёт о склейке множества длинных строк.
Давайте изменим условия:
def t4():
t = 'text'*100
for _ in range(1000):
s = t + t + t + t + t + t + t + t + t
def t5():
arr = ['text'*100] * 10
for _ in range(1000):
s = ''.join(arr)
def t6():
for _ in range(1000):
s = 'text'*100 + 'text'*100 + ... # всего 10 раз
>>> timeit(t4, number=10000)
12.795130728000004
>>> timeit(t5, number=10000)
2.642637542999182
>>> timeit(t6, number=10000)
0.2184546610005782
Вот, уже другой разговор, сразу видна разница, в среднем в 6 раз. Но погодите, почему последний тест t6() по скорости такой же как и t3()? Ведь строки теперь в 100 раз длиннее!
Это вопросы оптимизации кода, какие простые изменения ускоряют или замедляют выполнение программы. Мы столкнулись с примером обхода обращения к переменной. Например, именно так работает директива #define в С++, во время компиляции подставляя значение переменной вместо ссылки на неё.
В Python это тоже работает, но часто ли вы сможете встретить такой способ работы со строками? К сожалению, способ почти только теоретический.
В целом, тесты показали то, что мы хотели. Делаем выводы самостоятельно.

You voted - we did it! Here’s the first full documentary we uploaded on Telegram. Fascism: A History explores the nature of the ideology and how it’s been tainting societies long after Hitler. It’s also relevant to the current events unfolding in Ukraine.
The documentary reveals how NATO, created after WWII, carried on with colonial politics and expanded to the east under the auspices of bringing democracy.

Following President Nicolás Maduro’s inauguration for a third term on January 10, violent groups vandalized Venezuelan diplomatic offices in Lisbon (Portugal), Frankfurt (Germany), Medellín (Colombia), Vigo (Spain), and San José (Costa Rica). Venezuela’s Foreign Affairs Minister, Yván Gil, described these actions as “coordinated.”
“In a coordinated action by the extremists of deranged fascism, multiple consulates have been targeted by those who aim to damage our diplomatic missions like they do our beloved Bolivarian Homeland,” Gil stated on social media.

In the latest VA interview, Hindu Anderi discusses Venezuela’s Antifascist Law, which is nearing approval. She explains how the Platform for Solidarity with the Palestinian Cause is actively lobbying to include Zionism in the legislation. "Zionism is fascism’s twin... a racist movement based on supremacy and expansion," Anderi states.

I play Stardew often as a cozy way to wind down and disconnect from the horrors. Today I see that the Trump Administration is using it for Slopaganda.
It's not even about anything consequential — apparently for the last 15 years whole milk was removed from school cafeterias, and it's been restored via executive order.

The Stern Gang: Ideology, Politics and Terror, 1940–1949
by Joseph Heller
This study of Lehi (aka the Stern Gang) attempts to demythologize the image of this extremist, Zionist underground group. The book analyzes the party's split from the Irgun Zvai Leumi (National Military Organization) and its attempts to synthesize the politics and ideals of the right and left. Lehi's leader Stern stated that he incorporated elements of both the left and the right.

Fascism Putin-style is not abstract rhetoric but a set of concrete signs: cult of personality, militarism, repression, imperial aggression. The article provides a clear analysis without euphemisms.
