Local variables *Setting* a global variable from within a function is not as simple. Jan 13, 2017 As a result, any changes that you make in the function to these arguments do not affect the variable that was used to call the function, even if the  My class defines __del__ but it is not called when I delete the object. In our example   May 27, 2015 Variable assignment is a concept that many developers find confusing. Undefined function or variable 'x'. function (by reference not by value), that function changes that variable's value and when it  Notice that we don't specify the type of the variable: it's not changed by the Both functions are referring to the same variable, so that changing it one will affect  Variable not Updating Am I putting this in a wrong function or something?
