Jun 16, 2012 · Python is dynamically, but strongly typed, and other statically typed languages would complain about comparing different types. There's also the else clause: # This will always print either "hi" or "no hi" unless something unforeseen happens. if hi == "hi": # The variable hi is being compared to the string "hi", strings are immutable in Python, so you could use the 'is' operator.
Mar 21, 2023 · 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:
Dec 14, 2021 · For example, in some languages the ^ symbol means exponentiation. You could do that this way, just as one example: class Foo(float): def __xor__(self, other): return self ** other. Then something like this will work, and now, for instances of Foo only, the ^ symbol will mean exponentiation.
Jun 17, 2011 · An @ symbol at the beginning of a line is used for class and function decorators: PEP 318: Decorators. Python Decorators - Python Wiki. The most common Python decorators are: @property. @classmethod. @staticmethod. An @ in the middle of a line is probably matrix multiplication: @ as a binary operator.
Since is for comparing objects and since in Python 3+ every variable such as string interpret as an object, let's see what happened in above paragraphs. In python there is id function that shows a unique constant of an object during its lifetime. This id is using in back-end of Python interpreter to compare two objects using is keyword.
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 // 2 will return 2.0 since that's the floor division result of the operation.
Apr 25, 2017 · It's an operator in Python that can mean several things depending on the context.

Jul 26, 2009 · s = s.rstrip() For whitespace on the left side, use str.lstrip: s = s.lstrip() You can provide an argument to strip arbitrary characters to any of these functions, like this: s = s.strip(' \t\n\r') This will strip any space, \t, \n, or \r characters from both sides of the string. The examples above only remove strings from the left-hand and ...
Jan 17, 2013 · Simply -> is introduced to get developers to optionally specify the return type of the function. See Python Enhancement Proposal 3107. This is an indication of how things may develop in future as Python is adopted extensively - an indication towards strong typing - this is my personal observation.
