Lazy is an overly harsh and judgemental way to put it (virtually all programmers start with some high level simplified language), but the sentiment arises because it's syntax is designed to be easy for people writing code, but at the cost of people maintaining code.
The whitespace delimiters, the lack of type system, the lack of semi-colons ... They're all things that people who haven't programmed before think make programming easier. In reality they all make in the wild production programs waaay harder to maintain.
There's a reason that JavaScript has been surpassed by TypeScript for professional developers, and it did so remarkably quickly. All that 'extra' information that seems pointless for a new dev to express, in reality constrains your program, makes it more readable and understandable, reduces the amount of tests you have to write, and makes it easier for someone else to come in and make a change to it and be confident they haven't broken anything.
Python's type system is dramatically better than Javascript's though. Try doing things like
'' + Trueand Javascript will do incredibly stupid things. Python will just give you a type error. Also, look at things like==vs===in Javascript as well. That's the biggest reason why Typescript replaced it overnight. Python has found a better balance between productivity and error safety.In my opinion, the biggest shortcoming of Python's dynamic typing system is that you need to have very thorough test coverage to be sure that your code doesn't have semantic errors (a lot more than, say, Java). It has gotten better with the introduction of type hints, those I don't have much experience with them, so I can't say how much.
That is a large shortcoming.
Sure, but as with all things, it can depend on a lot of factors. All code needs some degree of testing, though one could certainly argue that Python needs more than Java and Java needs more than Rust/Haskell/etc. So you could argue that the productivity gain of using Python is offset by the productivity loss of extra testing. It's still hard to say which one wins out in the end.
People underestimate the cost of testing.
Removing the need for entire classes of tests cases is a huge win
