I just recently joined the python3 HypeTrain. However I just wondered how you can use an if statement onto a boolean. Example: RandomBool = True # and now how can I check this in an if statement? Like the following: if RandomBool == True: # DoYourThing And also, can I just switch the value of a boolean like this?

Dec 8, 2013 · Which is using python's operator chaining to mean: does the valuee of ii anded with 5 equal both i and 10. Obviously this will never be true. You would actually get (seemingly) the right answer if you had included brackets to force the precedence, so:

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 ...

Jul 5, 2010 · See the Truth Value Testing section of the Python documentation for more information. In particular: Operations and built-in functions that have a Boolean result always return 0 or False for false and 1 or True for true, unless otherwise stated. (Important exception: the Boolean operations or and and always return one of their operands.)

Mar 21, 2010 · Note that this is pseudo-code not Python code. In Python you cannot create functions called and or or because these are keywords. Also you should never use "evaluate" or if bool(...). Customizing the behavior of your own classes. This implicit bool call can be used to customize how your classes behave with and, or and not.

Python Ternary Operator. In some languages including Java, C/C++, C#, etc. you can assign a value based on the result of an inline boolean expression. For example, return (i < x) ? i : x This will return i if i < x, otherwise it will return x. I like this because it is much more compact in many cases than the longer syntax which follows.

Python "first evaluates x; if x is false, its value is returned; otherwise, y is evaluated and the resulting value is returned." So the syntax x and y can not be used for element-wised logical-and since only x or y can be returned. In contrast, x & y triggers x.__and__(y) and the __and__ method can be defined to return anything we like.

But when I apply the boolean not operator, the result is a syntax error: Python 2.7 (r27:82500, Sep 16 2010, 18:02:00) [GCC 4.5.1 20100907 (Red H... Skip to main content Stack Overflow

Apr 30, 2017 · Python logical or: A or B: returns A if bool(A) is True, otherwise returns B; Python logical and: A and B: returns A if bool(A) is False, otherwise returns B; To keep most of that way of thinking, my logical xor definintion would be: def logical_xor(a, b): if bool(a) == bool(b): return False else: return a or b
