5.10    Operators

Python uses essentially the same operators as most other programming languages. However, I would like to point out a few special features:

• DivisionThe / operator always performs floating point division, even if both operands are integers. To perform an integer division, you must use the // operator.

• Associating assignments with calculationsAssignments can be associated with basic arithmetic operations. In other words, a=a+1 can also be formulated as a+=1. Not only is this short notation allowed for basic arithmetic operations, but for almost all Python operators as well. In contrast to other programming languages, however, a++ and a-- in the sense of a=a+1 and a=a-1 are not allowed.

• Multiple comparisonsMultiple comparisons ...
