The logical operator AND && will return true if multiple conditions are all true, and
OR ||
will return true if at least one condition is true. The else statement will execute code if the condition was false. The while statement will repeatedly execute the same code while a condition is true.
What happens when an IF condition is true?
If one of the conditions is true
it will execute Action2
. If none are true, it will do nothing. will result in the possibility of both actions occurring when A > X and B > Y are both true.
Which Boolean return true only if both inputs are true?
The logic operation
AND will return a true value only if both inputs have a true value. Otherwise, if one or both inputs contain a false value, the AND gate will output a false value.
How does or work in Python?
In short, the Python or operator
returns the first object that evaluates to true or the last object in the expression
, regardless of its truth value. In this example, the Python or operator returns the first true operand it finds, or the last one. This is the rule of thumb to memorize how or works in Python.
How can I check if a statement is true?
A statement is true
if what it asserts is the case
, and it is false if what it asserts is not the case. For instance, the statement “The trains are always late” is only true if what it describes is the case, i.e., if it is actually the case that the trains are always late.
Can both IF and ELSE IF be true?
Use two if statements if both if statement conditions could be true at the same time
. In this example, both conditions can be true. You can pass and do great at the same time. Use an if/else statement if the two conditions are mutually exclusive meaning if one condition is true the other condition must be false.
Which loop is guaranteed to execute at least once?
while loop
is guaranteed to execute at least one time.
Is 1 True of false?
BUT the language derives true and false in an unusual way. Basicly there is no boolean value. The number 0 is considered to be false and all other numbers are considered to be true…. …
1 is considered to be true because it is non-zero
.
Is true and false true?
True is written
: true; False is written: false; Not is written in a variety of ways. In Matlab it is the tilde (~).
What are the 7 logic gates?
There are seven basic logic gates:
AND, OR, XOR, NOT, NAND, NOR, and XNOR
. The AND gate is so named because, if 0 is called “false” and 1 is called “true,” the gate acts in the same way as the logical “and” operator.
What is Python mainly used for?
Python is commonly used for
developing websites and software, task automation, data analysis, and data visualization
. Since it’s relatively easy to learn, Python has been adopted by many non-programmers such as accountants and scientists, for a variety of everyday tasks, like organizing finances.
What does == mean in Python?
The == operator compares the value or equality of two objects, whereas the Python is
operator checks whether two variables point to the same object in memory
. In the vast majority of cases, this means you should use the equality operators == and !=
What does != Mean in Python?
In Python != is defined as
not equal to operator
. It returns True if operands on either side are not equal to each other, and returns False if they are equal.
Can you have two if statements in Excel?
It is possible to nest multiple IF functions within one Excel formula
. You can nest up to 7 IF functions to create a complex IF THEN ELSE statement. TIP: If you have Excel 2016, try the new IFS function instead of nesting multiple IF functions.
What statement is true and false?
A true-false statement is any sentence that is
either true or false but not both
. A negation of a statement has the opposite meaning of a truth value.
What’s a true or false question?
A true or false question consists of
a statement that requires a true or false response
. There are other variations of the True or False format as well, such as: “yes” or “no”, “correct” or “incorrect”, and “agree” or “disagree” which is often used in surveys.
