Elegant ways to support equivalence (equality) in Python classes
When writing custom classes it is often important to allow equivalence by means of the == and != operators. In Python, this is made possible by implementing the __eq__ and __ne__ special methods, respectively. The easiest way I’ve found to do this is the following method:

Il y a 2 joursIn-place Operators¶. Many operations have an in-place version. Listed below are functions providing a more primitive access to in-place operators than the usual syntax does; for example, the statement x += y is equivalent to x = operator.iadd(x, y).Another way to put it is to say that z = operator.iadd(x, y) is to the compound statement z = x; z += y.

18 sept. 2023In Python, operators are special symbols, combinations of symbols, or keywords that designate some type of computation. You can combine objects and operators to build expressions that perform the actual computation. So, operators are the building blocks of expressions, which you can use to manipulate your data.

In Python, are the following two tests for equality equivalent? n = 5 # Test one. if n == 5: print ‘Yay!’ # Test two. if n is 5: print ‘Yay!’ Does this hold true for objects where you would be comparing instances (a list say)? Okay, so this kind of answers my question: L = [] L.append (1) if L == [1]: print ‘Yay!’

Python equivalent of which() in R – Stack Overflow
Python equivalent of which () in R. I am trying to take the following R statement and convert it to Python using NumPy: 1 + apply (tmp,1,function (x) length (which (x [1:k] < x [k+1]))) Is there a Python equivalent to which ()? Here, x is row in matrix tmp, and k corresponds to the number of columns in another matrix. lesoutrali bot
