How do you check if a list is not empty in Python?
Answers
Python treats empty lists as False, therefore if a list were supplied as an argument, the bool() function would return False. Placing a list within an if statement, utilizing the len() methods, or comparing it to an empty list are additional ways to determine if a list is empty.
What is meant by Python?The programming language Python is high-level and versatile. The off-side rule is used extensively in its design philosophy, which places a strong emphasis on code readability. Both Python's types and trash collection are dynamic. Python is a popular programming language for computers that is used to create software and websites, automate processes, and analyse data. Python is a general-purpose language, which means that it may be used to make a wide range of programmes and isn't tailored for any particular issues. As a programming language that prioritises readability, Python can be seen as beginner-friendly because it is simpler to comprehend and use. As a result of its syntax's resemblance to the English language, it is simple for new programmers to dive right into the realm of development.To learn more about Python, refer to:

To check if a list is not empty in Python, you can use the len() function to get the length of the list and then compare it to zero. If the length is greater than zero, then the list is not empty. Here's an example:
my_list = [1, 2, 3]
if len(my_list) != 0:
print("The list is not empty")
Output: The list is not empty
Alternatively, you can use a boolean expression to check if the list is not empty, like this:
if my_list:
print("The list is not empty")
Output: The list is not empty
Both of these methods will work, but using the boolean expression is more concise and Pythonic.

A brick has a weight of 23N. The brick is flat and smooth on the side in contact with the floor having measurements ( height= 5cm, length =20cm, width=10cm).
A)Calculate the area of the brick in contact with the floor. Give your answer in cm2.
B)Calculate the pressure of the brick on the floor.
Answers
Answer:
A)Area = 200\(cm^{2}\)
B) Pressure = 0.115 N/\(cm^{2}\)
Explanation:
Assuming that the brick is flat on the floor with its largest face towards the floor and not on its side, then we can calculate the area of that face by multiplying the length by the width like so...
Area = length * width
Area = 20cm * 10cm
Area = 200\(cm^{2}\)
The formula for calculating pressure is force divided by area. Therefore, since we just finished calculating the area and the force is given to us in the question (23N) we can simply plug in these values and solve for the pressure.
Pressure = Force / Area
Pressure = 23N / 200\(cm^{2}\)
Pressure = 0.115 N/\(cm^{2}\)
