{{ sec_header(name="Weird Syntax") }}

• It is hard to read, because it is missing semicolons and braces.
• Indentation as a syntactical element is just silly. This takes away freedom from the developer and makes the code less readable without any benefit.
• Indentation-dependant scopes make multiple statements on one line look horrible.
• Doc comments
  • They use triple quotes which doesn't make sense for a comment.
  • They go under what they are documenting, which looks wrong and is very unusual.
  • They are technically not comments, which is a terrible idea.
  • They are accessible at runtime, but shouldn't since this encourages spaghetti code.
• The def keyword does not imply a function, so one may think it is declaring a variable, or something else.
• Strange naming
  • __init__ or __add__ looks like an internal function. That these define operators looks like someone was too lazy to do this properly (yet again!).
  • Exception handling using raise and except instead of the usual throw and catch. There is literally no point to do this, and it confuses users.
  • Same goes for elif instead of else if. This is just pointless, and again looks like a lazy implementation.
• Strange symbols
  • not, and and or instead of the more conventional and cleaner looking !, && and ||.
• Normal if and else statements are not expressions. If they were, the additional ternary operator syntax would be completely redundant, and the code would be cleaner.
• The syntax for inheritance looks really confusing. Foo(Bar) looks like Foo has a constructor that takes a Bar as an argument, and not like Foo extends Bar.
• For some reason, the pass keyword exists. Why can't we just leave the block empty or omit the :? Yet another lazy implementation!
• The recently added := (assignment expression) operator exists, instead of simply making the normal assignment (=) an expression.
• True and False are capitalized which is unconventional and annoying.
• Functions can have named arguments like foo(bar=baz) which looks strange, and instead functions should just take dictionaries instead like foo({bar: baz})

{{ sec_header(name="Lacking Features") }}

• Lambdas are a poorly implemented afterthought.

{{ sec_header(name="Intepreter") }}

• Intepreters lead to runtime errors which could otherwise be detected at compile time. This often causes bad errors to make it into production due to untested edge cases.
• Very bad performance.
• Python is hard to package. Of course tools exist that can do it, but they are slow and large as they always include the interpreter as opposed to compiling the code or using some sort of faster intermediate language. Packaged python also includes the source code, which may be undesirable.

{{ sec_header(name="Error Handling") }}

• It has exceptions! The second most common mistake in OOP languages after null! Exceptions make error handling inherently unsafe, as there is no knowing when an exception might come flying at you!
• ExceptionGroups (introduced in 3.11, preview version at the time of writing) make this mess of exceptions even more intertwined. Error spaghetti, anyone?

{{ sec_header(name="Dynamic Typing") }}

• Passing an invalid type into a function may cause unpredictable behaviour. Manual type checks are annoying, and type hints are still just hints.
• It is often unclear what type a function is expecting, thus it can be hard to know how to call it, especially if it is undocumented.
• A function can return whatever type it wants, so it is hard to work with and unpredictable.
• Variables don't need to be declared. This leads to many issues, such as accidentally overwriting other variables with the same name, or typos going undetected.
• A variable's type may be changed after its assignment, making it harder to work with.

{{ sec_header(name="Poorly done Classes") }}

• The self parameter being passed into functions explicitly is pointless boilerplate. Instead it should just be there implicitly, and static functions should be declared with a keyword such as static.
• Fields do not need to be declared. This leads to issues mentioned before. It also makes the data a class stores undefined, making it harder to work with. It is recommended to declare fields, but unfortunately not enforced.
• Enums are basically just classes, and are yet another lazy afterthought.

{{ sec_header(name="Wide Spread Because Of The Wrong Reason") }}

• Python is seen as "the beginner's language", and it really should not be. As said earlier on this website, Python has numerous issues that stop the newbie from quickly getting used to other PLs, by lacking basic functions.
• Python should only be used if you wanna handicap yourself into an inferior PL, just to see what you can do. No more, no less.

{{ sec_header(name="Other Issues") }}

• Strings can be evaluated as code, also encouraging spaghetti code.
• Doc comments are available at runtime using help(element), and they should not be, because this too encourages spaghetti code.
• The command line REPL prints Use exit() or Ctrl-Z plus Return to exit for no reason, instead of simply exiting.
• Operator chaning often works in completely nonsensical ways. For example False == False in [False] is treated as False == False and False in [False] and not as something that makes sense such as (False == False) in [False] or False == (False in [False]).

{{ sec_header(name="Conclusion") }}

Python is a bad programming language that no one should use. Please don't hesitate to quit using programs made in Python. If you continue using them, it will motivate the Python devs to keep making this garbage, plus programs written in Python are usually VERY slow. And NEVER, EVER, EVER, EVER use Python in your own programming shenanigans. It's YOUR project. You have full control over it. Why even use Python if that's the case?

And, one more thing:

Please spread the site so more people know the truth. It would mean the world to me. Thanks.
