Прочитайте файл .bag и вам нужно извлечь всю информацию. ⇐ Python

[Anonymous]

import bagpy
from bagpy import bagreader

b = bagreader('1.bag')

topics = b.topic_table['Topics']

for index, row in b.topic_table.iterrows():
print(f"Topic: {row['Topics']}, Type: {row['Types']}, Messages: {row['Message Count']}, Frequency: {row['Frequency']}")

Вывод, который у меня есть
