Which comparison operator checks for equality in Python?

• A. =
• B. ==
• C. !=
• D. ===

Answer: (B)

The operator that checks for equality in Python is the double equals sign (==). This operator is used to compare two values to determine if they are equal. When you use this operator in an expression, Python evaluates the expression and returns True if the values on either side are equal, and False if they are not.

For instance, if you have a statement like 5 == 5, the result would be True because both sides are equal. Conversely, 5 == 4 would result in False since the values do not match.

The other options do not serve the purpose of checking for equality in Python. The single equals sign (=) is used for assignment, not comparison. The exclamation mark followed by an equals sign (!=) means "not equal," which is used to check if two values are different. The triple equals sign (===) is not a valid operator in Python; it is commonly found in other programming languages like JavaScript but does not apply in Python's syntax for equality checks.
