Absolutely wrong.

PASCAL was invented by Professor Niklaus Wirth at ETH Zurich specifically for teaching structured programming, circa 1970 (year of first release). It's a descendant of ALGOL (1960), which was pretty much the first structured programming language and introduced functions that could be recursively invoked -- ALGOL is the ancestor of C and PL/I as well as Pascal and relatives (Modula-2, Oberon, etc) and is hugely important.

BASIC came out of Dartmouth College in the US in the mid-sixties and the emphasis was on interactive invocation: early BASIC was almost completely non-structured (GOTO for flow of control, minimal subroutines, IF statements with no ELSE).

While both Pascal and BASIC were intended as teaching languages, they took radically different views of what to teach. And Python is different again: Python has the virtue of a simple and consistent core syntax, but wasn't designed for teaching -- it was designed for scripting, and was developed in the early 1990s for computers with 2-3 orders of magnitude more resources than early BASIC and Pascal.

Object Pascal/Delphi (Delphi was Borland's proprietary implementation with RAD for Windows) is an outgrowth of Borland's Turbo Pascal from the early 1980s, which in turn took Wirth's Pascal and added some essentials that had been missing -- notably dynamically allocated strings, modules, and finally object encapsulation -- that made it much more suitable for writing serious code: for a while Turbo Pascal was a viable competitor for C on MS-DOS.

But Pascal is in no way related to BASIC.
