Aug 5, 2012 · A self printing program is, as is its name, self explanatory. Today I thought about how to implement a quine in Python, I whipped up a solution... Let’s talk about self printing programs (or, quines).

It's called a quine, and there's a site that collects them. Yes. A programme that can make a copy of itself is called a "quine". The basic idea of most quines is: You write code that takes a string literal s and prints it, while replacing occurrences (or the occurrence) of a special substring foo in s by the value of s itself.

Oct 5, 2012 · In your program, print the function itself. Just add this: print(my_func) and you'll get output exactly like you asked. Also, while your code now produces the output, you're using False as default value, instead of what was asked. You're also using lists for each parameter, and the question doesn't ask you to do that.

Jan 1, 2024 · You don't need to explicitly read the file in your program to achieve this. If you run the following command in Python it would also work: def write_itself(): code = 'def write_itself():\n\t code = {!r}\n\t print(code.format(code)) \nwrite_itself()' print(code.format(code)) write_itself()

The code functions by using the data to print the code (which makes sense since the data represents the textual form of the code), but it also uses the data, processed in a simple way, to print the textual representation of the data itself. Here are three small examples in Python3:

In print function, you can use commas (outside of «str») to separate items. When you try and go print(,), you are actually trying to print supposedly 2 items, but there is nothing there to be printed.

Apr 13, 2025 · $ go run self_print.go J. In J's command line environment, many programs, including the empty program (is nothing, takes no arguments, produces nothing), print themselves to standard output.

A self-printing program – also called a quine – is a program that prints out its own source code. I will describe one simple way to implement a quine that can be adapted to just about any programming language.

Jul 26, 2020 · We can write a bash script to simulate this behavior: It will just grow itself in size, without losing its purpose. After 3 runs of this script with bash run_intron.sh 3, the resulting intron.py...

Instead of changing the print function, you could make your own list class which inherits the built-in list and then override the __str__ method. Example: def __str__(self): return '\n'.join(str(item) for item in self) Example usage: Works exactly the same as the built-in list, has all the same methods and whatnot, except it prints differently.
