[Python] Invert bool value in one line

python beginner's personal remind memo

Edited in response to your indication It is said that it can be inverted and stored in a variable with not without returning. In other words, it was OK below. .. ..

python.py


li = []
result = bool(li)


turned_result = not bool(li)


print('result: ',result)
print('turned_result: ',turned_result)
# result: False
# turned_result: True

#### Previous one [It can be inverted by returning a return value with not! ](Https://scrapbox.io/amanatsu-knit-note/ [Python] Invert bool value with not at return) and apply it by immediate execution of lambda

python.py


li = []
result = bool(li)


turned_result = (lambda x: not bool(x))(li)


print('result: ',result)
print('turned_result: ',turned_result)
# result: False
# turned_result: True

I am a beginner with less than 1 year of experience. I would be grateful if you could hear the opinions of seniors, such as better methods and readability.
