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.
- a -= b
- Substract b from a, works on sets 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
