Python's == vs. is: A Detailed Explanation with Code Examples

In Python, == and is are both comparison operators, but they serve different purposes: == (Equality Operator) Example x = 10 y = 10 print(x == y) # Output: True; Overridable Its behavior can be customized for specific data types by defining the __eq__ method. Compares values Checks if two objects have the same value. is (Identity Operator) Example

3 Python: Input/Output, Operators, Data Types, Strings, List

In programming, membership tests are extremely popular and helpful and Python includes specific operators for membership checks, just like it does for a lot of other common operations. 7) Identity Operators. To find out if two operands have the same identity, Python has two operators, ‘is’ and ‘is not’.

flake8 complains on boolean comparison "==" in filter clause

is and == are different in SQLAlchemy because you cannot override the identity operator (is) in python.An expression like Model.column is False is always evaluated as False because the comparison always happens immediately in python and not the database. The result of comparing the identity of a column object and a boolean is always False.This inserts statements like WHERE FALSE or AND FALSE ...

Division in Python 2 vs Python 3. One important distinction to note is how division works across Python versions: In Python 2, the / operator performed floor division between integers (returning an integer); In Python 3, the / operator always performs true division (returning a float); The // operator performs floor division in both versions # Python 3 print(7 / 2) # Output: 3.5 print(7 // 2 ...
