No, as I already noted (see the post before yours), ‘C’ is the successor to ‘B’, which is an incomplete version of ‘BCPL’.
‘A’ (current incarnation is ‘A+’) was developed in 1988, which is nearly two decades after ‘C’ was developed by dmr, and did not figure in the naming of ‘C’.
‘A-0’, developed for UNIVAC computers in 1952 and was the first computer language to have a compiler, was not a general-purpose language in the sense we think of computer languages. I doubt that it figured in a decade where more powerful paradeigms like Algol, FORTRAN, and BCPL existed.
The best kinds of scripting languages are those that ‘byte-code-compile’, like Java, Tcl, and Basic. I don’t know much about Python. Does it do that?
Even so, any scripted language can never be as fast as a language that compiles to native machine code. For many cases this does not matter, for example with GUI interfacing… However, with heavy number-crunching it is noticeable; programs like Blender would be far too slow.
The friendly way (you might even say cavelier) that scripted languages handle data often impede true compilation to machine code. Systems exist which can get around this, but in the case of Python it would be hard-pressed to introduce significant speed-ups. (IMHO)
