Static typing and less language constructs mean it should have less overhead to execute after it is parsed. But when comparing these things you would have to account for the fact that a lot of function calls in python are backed by C, so it depends what you are doing. Also, while MEL might be faster in some cases, it is also not as convenient as Python when it comes to having more libraries and utilities at your disposal, and better integration with your development environment. MEL is really just glue code for calling all of the pre-built functions. > > *From:* python_inside_maya@googlegroups.com [mailto: > python_inside_maya@googlegroups.com] *On Behalf Of *Justin Israel > *Sent:* Monday, April 05, 2021 4:01 PM > *To:* python_inside_maya@googlegroups.com > *Subject:* Re: [Maya-Python] C++ speed/efficience in Maya > > > > > > > > On Tue, Apr 6, 2021 at 8:32 AM João Victor <joaovictor...@gmail.com> > wrote: > > Hey guys, > > Could somebody help me in some doubt? > > How faster C++ could be in Maya, compared to python API in general? > > Is this something that worth to work with for what kind of programs > (generally)? > > > > Python is considered a relatively "slow" language, compared to C++. > Because python is dynamically typed and interpreted, there is a lot more > overhead involved with every variable access or function call, where python > has to look up attributes and check types.
