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 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 That means if the first operand already defines the result, then the second
slice - How slicing in Python works - Stack Overflow Python slicing is a computationally fast way to methodically access parts of your data In my opinion, to be even an intermediate Python programmer, it's one aspect of the language that it is necessary to be familiar with
operators - Python != operation vs is not - Stack Overflow In a comment on this question, I saw a statement that recommended using result is not None vs result != None What is the difference? And why might one be recommended over the other?
python - Iterating over a dictionary using a for loop, getting keys . . . Why is it 'better' to use my_dict keys() over iterating directly over the dictionary? Iteration over a dictionary is clearly documented as yielding keys It appears you had Python 2 in mind when you answered this, because in Python 3 for key in my_dict keys() will still have the same problem with changing the dictionary size during iteration
The tilde operator in Python - Stack Overflow In Python, for integers, the bits of the twos-complement representation of the integer are reversed (as in b <- b XOR 1 for each individual bit), and the result interpreted again as a twos-complement integer So for integers, ~x is equivalent to (-x) - 1 The reified form of the ~ operator is provided as operator invert
