Definition of python in the Definitions.net dictionary. It means that 1 × 10−5. It is nothing but a scientific notation. Operators are the constructs which can manipulate the value of operands. These operators compare the values on either sides of them and decide the relation among them. What does -1 mean in numpy reshape? To begin with, your interview preparations Enhance your Data Structures concepts with the Python DS Course. x in y, here in results in a 1 if x is a member of sequence y. Evaluates to true if it does not finds a variable in the specified sequence and false otherwise. Compound “and” Expressions. What does the Double Star operator mean in Python?

But in Python, as well as most other programming languages, it means something different. Bitwise operator works on bits and performs bit by bit operation. [code]total += a [/code]is equivalent to: [code]total = total + a [/code](note in the title it said “total += a#” the # is the start of a comment, so that and anything after it on the same line would be ignored).
