• Python dictionary: add or increment entry

  - by cursa

  Hi everyone, I'm currently re-engaging with Python after a long absence and loving it. However, I find myself coming across a pattern over and over. I keep thinking that there must be a better way to express what I want and that I'm probably doing it the wrong way. The code that I'm writing is in the following form: # foo is a dictionary if…

  - by Srinivas Reddy Thatiparthy

Of course, evil client code can try…

• Memory allocation in case of static variables

  - by eSKay

  I am always confused about static variables, and the way memory allocation happens for them. For example: int a = 1; const int b = 2; static const int c = 3; int foo(int &arg){ arg++; return arg; } How is the memory allocated for a,b and c? What is the difference (in terms of memory) if I call foo(a), foo(b) and foo(c)?

• Pass-by-Reference Error

  I have a hook system setup... which is working on localhost... I put it live and get an error saying "Warning: Call-time pass-by-reference has been deprecated".

• Superfluous python parameters

  - by Leif Andersen

  I've noticed a discrepancy in the way that python parameters are called. In every other language I've dealt with, you either have foo() meaning either no parameters, or as many parameters as you like, or foo(arg1, arg2,...,argn) where you pass in the same number of parameters to define…
