Can Python Be Forced to Run “hello”(print)?

One extremely cursed approach is to use a library that modifies built-in types. For example, a tool such as forbiddenfruit can add a __call__ method to str, making the string pass itself to the function it is called with. Conceptually, it looks like this:

from forbiddenfruit import curse
curse(str, "__call__", lambda self, func: func(self))

"hello"(print)

This relies on implementation details and is definitely not something to use in normal code.

The basic idea would be monkey-patching str, assuming Python lets you alter the type's call behavior. In ordinary Python, built-in types are immutable and you cannot simply assign a new __call__ method to str, so you need a hacky third-party tool or low-level memory manipulation.

The practical answer is to use print("hello") or wrap the string in a custom callable class. Making a literal string callable requires modifying Python internals, so the result is more of a party trick than a reliable solution.

You can also attempt to overwrite part of Python's internal type structure with ctypes so that str objects appear callable. That involves creating a C-compatible callback and changing a function pointer inside the str type. It may work only on specific Python builds, can crash the interpreter, and is wildly unsafe, but it matches the requested level of cursed.
