The main point of Phython, at least from my point of view, is that is interpreter and easy to learn, similar as BASIC was back in the day. With many lib available, it is possible to accomplish almost anything in less steps and on many platforms. Nowadays, it is used in academic circles and universities as a primary language.
Python's unusual rise has a lot to do with the Linux community and distros, as a scripting language that came along at the right time and could be used instead of bash, csh, awk, etc... It was a "unifier" on that OS. It then allowed Linux users to bring it along with them, when using computers loaded with Windows. As the Linux community tended to be tech savvy, they built a lot of libraries. This appeared to "brew" for a while, then caught on in academic circles and universities. Its trajectory is unusual, compared to the huge companies that fueled the expansion of the other popular languages, at present. C was sparked by AT&T/Bell Labs, and lots of heavy hitters along the way. C# by Microsoft, Java by Sun/Oracle, etc... JavaScript was made the standard for browsers, so given a monopoly (for the time being). If you look at the less popular languages, you will often see they weren't as lucky with timing, nor created by or got backing by major corporations.
Debatably, Python got lucky. Because in many respects, many other languages could and can take its place, and it's a mess:
1) Python brings backward compatibility, version madness, and community splits with Python 2 VS Python 3, or even Python 3.5 VS Python 3.8
2) Python indentation burns the eyes and makes many crazy (off-side rule madness)
3) Many aren't fond of Python's pass-by-object-reference; change to the variable changes the reference everywhere, then it's like globals everywhere
4) Python is slower than other languages, and not suited for various tasks
5) No need to declare a variable or function, so mistype a variable name or function, then get an unexpected surprise
6) Variable names can be reused for something with a different type, more unexpected surprises now await
Not saying Python is the worse thing ever, but lets not act like it's for everyone. Many hate it, many love it.
Pascal is dead long time ago. Even it is used primarily as a language to teach students basics steps in computer science and until Borland, generally it was just a toy. But indeed, since now many programming languages are free of charge, Web oriented and well established, Pascal is pretty much outdated. Delphi as well, I do not see many compaties use it nowadays and offer jobs, at least in my country, except banks...
The argument about jobs is relative. Because not everybody is/wants to work for a company as a professional programmer. There are hobbyist, independent software developers, small business owners that create programs for their company, freelancers, students, etc... Even if the person is/wants to be a professional programmer: A) They can know multiple programming languages. B) They can find a niche, where they make money. So if the niche was working for banks, and they got paid well, I'm sure they will be fine.
This bizarre echo chamber to say every language not in the perceived/reported top 10 is "dead", is also ridiculous. Anybody can search Google, and see people saying Pascal or Delphi is dead,
for the last 15 years. Yet, here we are. Embarcadero is still making money selling Delphi, and still putting out new releases. RemObjects is still selling Oxygene. Free Pascal and Lazarus are still here, with updates. Yes, I'm sure Microsoft wants people to say every language not C#, is "dead", because they want everyone hooked on their product. But not everyone loves C#.
And if Object Pascal/Delphi is still being taught in schools around the world (Russia, Brazil, South Africa, Turkey, etc...) then clearly the language is not going to die any time within the next 15 years either.
