The left part may be false, but right part is true (python has "truth-y" and "fals-y" values), so the check always succeeds. The way to write what you meant to would be. if weather == "Good!" or weather == "Great!": or (in more common python style) if weather in ("Good!", "Great!"):

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:

Mar 21, 2010 · 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.

When you run python -m foo.bar, you are running the bar.py, instead of the installed module. However, if you are calling python -m foo.bar from any other directory, you are using the installed module. This behavior certainly doesn't happen if you are using python instead of python -m, and can be confusing for beginners. The reason is the order ...

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 ...

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.

Jun 17, 2011 · Functions, in Python, are first class objects - which means you can pass a function as an argument to another function, and return functions. Decorators do both of these things. If we stack decorators, the function, as defined, gets passed first to the decorator immediately above it, then the next, and so on.

Python 3.10 introduces the | union operator into type hinting, see PEP 604. Instead of Union[str, int] you can write str | int . In line with other type-hinted languages, the preferred (and more concise) way to denote an optional argument in Python 3.10 and up, is now Type | None , e.g. str | None or list | None .

Aug 31, 2008 · A Python dict, semantically used for keyword argument passing, is arbitrarily ordered. However, in Python 3.6+, keyword arguments are guaranteed to remember insertion order. "The order of elements in **kwargs now corresponds to the order in which keyword arguments were passed to the function." - What’s New In Python 3.6. In fact, all dicts in ...

Feb 25, 2012 · It depends on how you want to access the import when you refer to it. from urllib import request # access request directly. mine = request() import urllib.request # used as urllib.request mine = urllib.request()
