What is the Boolean operator that is true only if both of its subexpressions are true? What does the following code print: if (4 + 5 == 10): print('TRUE') else: print('FALSE')?
Understand the Problem
The question is asking for the identity of a specific Boolean operator and what a given Python code will print. It focuses on understanding logical expressions and conditionals in programming.
Answer
'and' operator; prints 'FALSE'.
The Boolean operator that is true only if both of its subexpressions are true is 'and'. The following code prints 'FALSE' because 4 + 5 is not equal to 10.
Answer for screen readers
The Boolean operator that is true only if both of its subexpressions are true is 'and'. The following code prints 'FALSE' because 4 + 5 is not equal to 10.
More Information
'and' is a logical conjunction operator that results in TRUE only if both operands are TRUE. The expression '4 + 5 == 10' evaluates to FALSE, so the code prints 'FALSE'.
Tips
A common mistake is confusing 'and' with 'or', which requires at least one operand to be TRUE.
