WebMathematicians commonly consider ordered pairs ; for instance, most analytical geometry is done with Cartesian coordinates ( x , y ), an ordered pair, double, or 2-tuple. An essential ingredient here is that a tuple has a fixed and known number of elements. For example a 2-dimensional geometric point might have a tuple with x and y . danhyang alchemy of souls

WebThe ordered pair ( a, a), as a set, is a set which can be written as { { a }, { a, a } } or as { { a }, { a } } or as { { a } }. There is no problem with this, because that set has the property that ( c, d) is equal to { { a } } if and only if c = d = a, which is exactly what we want. WebPython’s OrderedDict is a dict subclass that preserves the order in which key-value pairs, commonly known as items, are inserted into the dictionary. When you iterate over an OrderedDict object, items are traversed in the original order. If you update the value of an existing key, then the order remains unchanged. birth 2 math cst practice
