Sure!
In Python 3.10, not is a keyword that can be used for logical negation. It takes a single boolean value and returns the opposite boolean value.
Here are some examples to illustrate how to use not in Python 3.10:
Example 1:
x = True
y = not x
print(y) # False
In this example, we assign the boolean value True to variable x. We then apply the not operator to x and assign the result to variable y. The not operator returns the opposite of True, which is False. Finally, we print the value of y, which is False.
Example 2:
x = 10
if not x < 5:
print("x is greater than or equal to 5")
In this example, we use the not operator to check if the value of x is greater than or equal to 5. We apply the < operator to x and compare it to the value 5. However, we use the not operator to negate the result of this comparison, so that the code inside the if statement is executed only if x is greater than or equal to 5. In this case, the output will be "x is greater than or equal to 5".
Example 3:
x = None
if not x:
print("x is None or False")
In this example, we check if the value of x is None or False. We use the not operator to negate the boolean value of x. Since None and False are both "falsey" values in Python, the not operator will return True when applied to them. In this case, the output will be "x is None or False".
I hope that helps! Let me know if you have any further questions.
