Concatenating strings creates maple copies along the way, as each pair is concatenated and a new string is return for for the next addition. In small use cases it won't matter. But in loops and with tons of string it would be wasteful. Another reason is that using the + operator only works if both sides are strings. Whereas the format() method gives you string conversion operations like float formatting. > -- > You received this message because you are subscribed to the Google Groups > "Python Programming for Autodesk Maya" group. > To unsubscribe from this group and stop receiving emails from it, send an > email to [email protected]. > To view this discussion on the web visit > https://groups.google.com/d/msgid/python_inside_maya/d32cb68b-135f-443a-923a-83d7ae1f3034%40googlegroups.com > . > For more options, visit https://groups.google.com/d/optout. > -- You received this message because you are subscribed to the Google Groups "Python Programming for Autodesk Maya" group.
