I do it in a different branch & discard it afterwards. Having said that, I never meant print() should be used in place of a proper debugger. All I am saying is they both can complement each other and each one has its place & value. As for me, I find it quicker to add a few print statements and get a rough idea before firing up a debugger(if required). May be others are more proficient in using debuggers. But print() works for me.
