Hi Guys

I have a loop in Python that is responsible for the main functionality of my system. I have various string variables in the loop that are re-used on each iteration of the loop and are continuously assigned new string values.

I do not clear string variables before I assign them with new string values.

Should I be clearing each string variable before assigning a new string value??

Or are previous variable values completely overwritten when you assign a new value??

Thanks for all the help

Regards

Hi sach262,

if you're using assignment statements in the likes of
var1 = expression_yielding_a_string you'll be doing fine, whereas assignments like var1 += expression_yielding_a_String

will accumulate string content into var1.

Hope this helps.

Cheers

Manfred
