- 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:
- 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
- What is :: (double colon) in Python when subscripting sequences?
I know that I can use something like string[3:4] to get a substring in Python, but what does the 3 mean in somesequence[::3]?
- Is there a not equal operator in Python? - Stack Overflow
There's the != (not equal) operator that returns True when two values differ, though be careful with the types because "1" != 1 This will always return True and "1" == 1 will always return False, since the types differ Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types There's also the else clause:
- operators - Python != operation vs is not - Stack Overflow

- 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
