Как правильно проверить атрибуты доступа файла? То есть доступна ли запись в файл или является ли он исполняемым?
Для этого в Python есть функция os.access()
Проверять так:
os.access(path, flag)
Функция вернёт bool в зависимости от наличия указанного флага.
Всего есть 4 флага проверки:
os.F_OK - наличие файла на диске
os.R_OK - доступ на чтение
os.W_OK - доступ на запись
os.X_OK - доступ на исполнение
Например, вместо try-except лучше делать так (пример из документации):
if os.access("myfile", os.R_OK):
with open("myfile") as fp:
return fp.read()

We can use Short-Term Holder MVRV to monitor the unrealized profit or loss of new market participants. Comparing the STH cost-basis to the spot price reveals the pressure they face to sell at a loss or take profit.
#MVRV is already above the 1.0 Mark, which shows strong bullishness in the market and #MVRV tested the Moving Average as Resistance already, and more momentum yet to come if it crosses the 155D Moving Average with MVRV

#MVRV started flipping bullish as #MVRV Ratio flipping above the 1Y MRVR Moving Average. Historically, we've seen this indicating some good mid-term and long-term trends successfully, so this could be another indication to us.

🚀 Bitcoin's Potential Bear-Market 'Iron Bottom' Predicted by Analyst
A CryptoQuant analyst has projected that Bitcoin might establish a bear-market 'iron bottom' within the $55,000–$60,000 range by the end of 2026. According to NS3.AI, this prediction is grounded in on-chain indicators, notably the MVRV Z-score, which has moderated but remains above negative levels.
