  • 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:
  • 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:
  • Using or in an if statement (Python) - Stack Overflow
    Using 'or' in an 'if' statement (Python) [duplicate] Asked 7 years, 10 months ago Modified 2 months ago Viewed 162k times
  • 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 - 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
  • 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?
  • Does Python have a ternary conditional operator?
    Python is a syntax-rich language with lots of idiomatic tricks that aren't immediately apparent to the dabbler But the more you learn and understand the mechanics of the underlying system, the more you appreciate it
