Python:Operators: Difference between revisions

Most operators work as you would expect.

<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.

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