Jan 14, 2020 · 78. // is the floor division operator. It produces the floor of the quotient of its operands, without floating-point rounding for integer operands. This is also sometimes referred to as integer division, even though you can use it with floats, because dividing integers with / used to do this by default. In Python 3, the ordinary / division ...
Dec 12, 2009 · a += b is essentially the same as a = a + b, except that: + always returns a newly allocated object, but += should (but doesn't have to) modify the object in-place if it's mutable (e.g. list or dict, but int and str are immutable). In a = a + b, a is evaluated twice. Python: Simple Statements. A simple statement is comprised within a single ...

May 27, 2010 · Similarly, * and ** can be used for parameters. Using * allows a function to accept any number of positional arguments, which will be collected into a single parameter:. def add(*values): s = 0 for v in values: s = s + v return s
Aug 3, 2023 · In Python, the double slash (//) is known as the floor division operator. It performs division similar to the traditional division (/) operator but rounds down the result to the nearest whole number. This means that any decimal part of the result is discarded, leaving only the integer part. The floor division is useful in scenarios where you ...
