2.4. PRINT AND OUTPUT FORMATS Page 19The truth table for the AND operator ∧ is given as follows.True ∧ True = True (2.5)True ∧ False = FalseFalse ∧ True = FalseFalse ∧ False = FalseThe truth table for the OR operator ∨ is given as follows.True ∨ True = True (2.6)True ∨ False = TrueFalse ∨ True = TrueFalse ∨ False = False2.3.6 Membership OperatorsWith the membership operators you can check whether a value or an object is part of sequence of objects.Operator Comment Examplein is member x = 2 in (1,2,3) >>> Truenot in is not a member x = 2 not in (1,2,3) >>> False2.3.7 Identity OperatorsWith the identity operators you can check the identity of two objects.Operator Comment Exampleis is identical x = (1,2) >>> y = x >>> x is y >>> Trueis not is not identical x = (1,2) >>> y = x >>> x is not y >>> False2.4 Print and Output FormatsIf you want to print data into the console window, you have to think about formating. The formatingsequences are very similar to the formating sequences of the C printf function. The formating is a socalled escape sequence within a string, which is started with the % operator.The most common formats are the following.• formating an integerAn integer (independent of the data type) is formated by the escape %d for decimal representationand %x or %X for hexadecimal representation.• formating a floatA float is formated by the escapes %f, %e, %E, %g and %G2.12.2011
