PCEP Practice Question: Data Types, Variables, Basic I/O and Operators
Which operator is used to check if two values are equal in Python?
⚠ Common exam trap
Python Institute often tests the confusion between the assignment operator = and the equality operator ==, as beginners mistakenly use = in conditions like if x = 5 instead of if x == 5, which causes a syntax error or unintended assignment.

Correct answer & explanation
✓
==
The == operator is Python's equality comparison operator, used to check if two values are equal. It returns True if the values are equal and False otherwise, making it the standard way to test equality in conditions and expressions.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
=
Why it's wrong here
The single equals sign is the assignment operator, binding a name to a value rather than comparing operands. It is tempting because it appears in equality expressions in mathematics, but Python reserves == for value comparison; = would raise a SyntaxError inside an if condition.
- ✗
eq
Why it's wrong here
Python has no eq operator; equality comparison uses the double equals sign ==. The token is tempting because it resembles equality notation from other languages and the __eq__ method name, but writing eq between two values is a syntax error, not a comparison.
- ✗
!=
Why it's wrong here
The != operator tests inequality, returning True when operands differ, so it cannot check equality. It is tempting because it appears in the same comparison family, and it would be the correct choice when you specifically need to confirm two values are not the same.
- ✓
==
Why this is correct
The `==` operator performs a value equality comparison, returning `True` when both operands hold equivalent values and `False` otherwise. This directly satisfies the stem's requirement to check whether two values are equal, unlike `=` which assigns, or `is` which tests object identity rather than value equivalence.
