  • 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:
  • python中=与==和：=的区别是什么？ - 知乎
    本文讨论了Python中=、==和:=的区别及其使用场景，帮助读者更好地理解这些运算符的功能和用法。
  • 如何系统地自学 Python？ - 知乎
    Python初学者的法宝，如果你想下载Python，最好还是在这个网址去下，不要想着用一些不明来源的安装包。 在这里，你不仅可以下载各种版本的Python源代码和安装程序，更有各种文献资料、Python交流社区，还会告诉你Python的最新行情，不得不感叹，这功能太强大！
  • What is :: (double colon) in Python when subscripting sequences?
    In Python 3, your example range (N) [::step] produces a range object, not a list To really see what is happening, you need to coerce the range to a list, np array, etc
  • 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:
  • 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
  • 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
