Python:Operators

Most operators work as you would expect.

Less obvious assignment

<int> * <string>

Repeat <string> <int> times. Negative <int>s return an empty string.

a / b

Divide to floating point. In python2 the result datatype is determined by the arguments datatype i.e. both arguments int => result is int.

a // b

Divide to integer (truncated, not rounded)

a % b

Modulo

a ** b

Power

a << b

bit-shift left

a >> b

bit-shift right

undef(a)

Remove variable a (Note: variables are pointers to objects, the object may not be removed)

Self assign

a += b

Add b to a, works with other operators and on strings too.

Compare

==, >, <, <=, >=, !=

Just as you would expect

Boolean

and, &

Logical and

or, |

Logical or

^

Logical Xor (exclusive or)

not

Negate the result of the next expression
