- What is Pythons equivalent of (logical-and) in an if-statement?
There is no bitwise negation in Python (just the bitwise inverse operator ~ - but that is not equivalent to not) See also 6 6 Unary arithmetic and bitwise binary operations and 6 7 Binary arithmetic operations The logical operators (like in many other languages) have the advantage that these are short-circuited
- What does colon equal (:=) in Python mean? - Stack Overflow
In Python this is simply = To translate this pseudocode into Python you would need to know the data structures being referenced, and a bit more of the algorithm implementation Some notes about psuedocode: := is the assignment operator or = in Python = is the equality operator or == in Python There are certain styles, and your mileage may vary:
- What is the reason for having in Python? [duplicate]
In Python 3, they made the operator do a floating-point division, and added the operator to do integer division (i e , quotient without remainder); whereas in Python 2, the operator was simply integer division, unless one of the operands was already a floating point number
- python - What does the caret (^) operator do? - Stack Overflow
Side note, seeing as Python defines this as an xor operation and the method name has "xor" in it, I would consider it a poor design choice to make that method do something not related to xor like exponentiation I think it's a good illustrative example of how it simply calls the __xor__ method, but to do that for real would be bad practice

- python - Is there a difference between == and is? - Stack Overflow
According to the previous answers: It seems python performs caching on small integer and strings which means that it utilizes the same object reference for 'hello' string occurrences in this code snapshot, while it did not preform caching for 'hello sam' as it is relatively larger than 'hello' (i e it manages different references of 'hello sam
