  • 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
    1 You can use the != operator to check for inequality Moreover in Python 2 there was <> operator which used to do the same thing, but it has been deprecated in Python 3
  • 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
  • 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 - Is there a difference between == and is? - Stack Overflow
    According to the previous answers: It seems python performs caching on small integer and strings which means that it utilizes the same object reference for 'hello' string occurrences in this code snapshot, while it did not preform caching for 'hello sam' as it is relatively larger than 'hello' (i e it manages different references of 'hello sam
  • math - ` ` vs ` ` for division in Python - Stack Overflow
    In Python 3 x, 5 2 will return 2 5 and 5 2 will return 2 The former is floating point division, and the latter is floor division, sometimes also called integer division In Python 2 2 or later in the 2 x line, there is no difference for integers unless you perform a from __future__ import division, which causes Python 2 x to adopt the 3 x behavior Regardless of the future import, 5 0
  • python - What is the purpose of the -m switch? - Stack Overflow
    Python 2 4 adds the command line switch -m to allow modules to be located using the Python module namespace for execution as scripts The motivating examples were standard library modules such as pdb and profile, and the Python 2 4 implementation is fine for this limited purpose
  • 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]?
