  • 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:
  • syntax - What do gt; gt; and lt; lt; mean in Python? - Stack Overflow
    I notice that I can do things like 2 << 5 to get 64 and 1000 >> 2 to get 250 Also I can use >> in print: print >>obj, "Hello world" What is happening here?

  • 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
