In September 2025, following the suicide of a 16-year-old, OpenAI said it planned to add restrictions for users under 18, including the blocking of graphic sexual content and the prevention of flirtatious talk. In August 2024, OpenAI announced it had created a text watermarking method but did not release it for public use, saying that users would go to a competitor without watermarking if it publicly released its watermarking tool. Later reports showed the bug was much more severe than initially believed, with OpenAI reporting that it had leaked users’ “first and last name, email address, payment address, the last four digits (only) of a credit card number, and credit card expiration date”. Shortly after the bug was fixed, users could not see their conversation history. OpenAI CEO Sam Altman said that users were unable to see the contents of the conversations.

That’s why the idiomatic way of making a shallow copy of lists in Python 2 is You can make any of these positive or negative numbers. Python slicing is a computationally fast way to methodically access parts of your data. This may also clarify the difference between slicing and indexing.
Python Version: 3.X
The non-keyword arguments get packed into a list called args inside the function body and the keyword arguments get packed into a dict called kwds inside the function body. These are keyword arguments which are set of named arguments which are passed as key/value pair or dictionary separated by , if multiple. These are called keyword arguments here also you can pass variable numbers of arguments but the arguments are much like a dictionary k/v pair. This is a shortcut that allows you to pass multiple arguments to a function directly using either a list/tuple or a dictionary.
And let’s say that you want to import the mango module. Programmatically importing modules was introduced in Python 3.1 and gives you more control over how modules are imported. Fourth import the module inside the folder in name-file.py
What does the “at” (@) symbol do in Python?
The integration used ChatGPT to write prompts for DALL-E guided by conversations with users. In March 2023, ChatGPT Plus users got access to third-party plugins and a browsing mode (with Internet access). Over many iterations of ChatGPT, plus users maintained more access to better models than the free tier provided, and access to additional features like voice mode. Premium users were originally limited in the number of messages they could send to the new model, but OpenAI increased and eventually removed these limits. GPT-4, which was released on March 14, 2023, was made available via API and for premium ChatGPT users.
Very handy if you use python pip to install packages. If you have added the Python in the path, it’ll show as “path” in your environmental variable account. To know where Python is installed you can execute where python in your cmd.exe. It is compatible with all available versions of python. If You want the Path After successful installation then first open you CMD and typepython or python -i (You can also look in sys.path for reasonable locations.)
Here is a quick example,suppose I define a read_a_book function on Ipython If we daman game download stack decorators, the function, as defined, gets passed first to the decorator immediately above it, then the next, and so on. This is a demonstration that we can call a function that’s a decorator first, as well as stack decorators. (If this difference makes a difference in the meaning of your code, you should reconsider what you’re doing with your life, because that would be pathological.) See the documentation for function definitions and class definitions for more about decorators.
Pseudocode is an informal high-level description of the operating principle of a computer program or other algorithm. What you have found is pseudocode Can someone explain how to read this snippet of code? In July 2024, Futurism reported that GPT-4o in ChatGPT would sometimes link “scam news sites that deluge the user with fake software updates and virus warnings”; these pop-ups can be used to coerce users into downloading malware or potentially unwanted programs. However, there were important shortfalls like violating basic linear algebra principles around solving singular matrices and producing matrices with incompatible sizes. ChatGPT was able in 2023 to provide useful code for solving numerical algorithms in limited cases.
- In my opinion, you will understand and memorize better the Python string slicing notation if you look at it the following way (read on).
- It can help if you want to use this enviorment when you need to connect this to other applications, where you want to integrate some python code.
- B”hello” is not a string (even though it looks like one), but a byte sequence.
- This makes all names from the module available in the local namespace.
What does ** (double star) and * (star) do for parameters?
A caveat, it doesn’t support negative arguments to start, stop, or step, so if that’s an issue you may need to calculate indices or reverse the iterable in advance. Since slices of Python lists create new objects in memory, another important function to be aware of is itertools.islice. If you need to know the installed path under Windows without starting the python interpreter, have a look in the Windows registry.
The decorator syntax is simply only a syntactic sugar. “Callable” is used here instead of “function” with premeditation. Decorators were added in Python to make function and method wrapping (a function that receives a function and returns an enhanced one) easier to read and understand. Nothing stops me equipped with decorator. Solve the problem by thinking different and define a new_function Nevertheless, what if I’m not allowed to manipulate the original function, or if there are thousands of such function to be handled.
Reading kwargs doesn’t required to enumerate over a loop and order of arguments don’t matter. And can read it in the function individually as So if the first argument is supposed to be a string and second and integer, if the caller messed with the order the function fails. Although this is very easy to implement and use the order of arguments matters a lot here. It will print arguments in order of placement as 1,2,3… Is used to pass n-numbers of arguments in order much like a Array every element will follow and index.
- @ can be a math operator or a DECORATOR but what you mean is a decorator.
- Despite this, users may “jailbreak” ChatGPT with prompt engineering techniques to bypass these restrictions.
- To know where Python is installed you can execute where python in your cmd.exe.
The rules of slicing are as follows:
In file_b.py, I would like to import a class A in file_a.py under the folder a. In python 3, you don’t need __init__.py in your project subdirectory due to the Implicit Namespace Packages. In my case I had a class to import. Now run main_module.py; the output will be This structure allows using and accessing sub-packages, parent package, and sibling packages and modules. I was faced with the same challenge, especially when importing multiple files, this is how I managed to overcome it.
Use with string formatting
After the decorator is defined, we simply use it as follows. Func is the function that is being decorated.In the inner function wrapped_func, we can do whatever before and after the func is called. This will reduce the number of method signatures inside of the classand make code more readable and maintainable. The best syntax for creating properties is using property as a decorator. This is often true when the decorator needs complex parametrization or it depends on a specific state.
A dictionary in Python is a collection of key-value pairs. If you want to loop over a dictionary and modify it in iteration (perhaps add/delete a key), in Python 2, it was possible by looping over my_dict.keys(). How does Python recognize that it needs only to read the key from the dictionary? In ..-syntax, it always iterates over the keys (the values are accessible using dictionarykey).
This makes all names from the module available in the local namespace. And if name in X ischanged to point to some other object, your module won’t notice. Imports the module X, and creates a reference to that module in thecurrent namespace. First of all, let me explain exactly what the basic import statements do. Many people have already explained about import vs from, so I want to try to explain a bit more under the hood, where the actual difference lies.
It means “all elements of the sequence but the last”. This works on any sequence, not just strings. What always work is to think in characters or slots and use indexing as a half-open interval — right-open if positive stride, left-open if negative stride. I don’t think that the Python tutorial diagram (cited in various other answers) is good as this suggestion works for positive stride, but does not for a negative stride. With that in mind, subscription and slicing are straightforward. Most of the previous answers clears up questions about slice notation.
Will simply loop over the keys in the dictionary, rather than the keys and values. This will add the base directory to the path to executable python, and then classes will be accessible via a non-relative import. You can add the parent directory to PYTHONPATH, in order to achieve that, you can use OS depending path in the “module search path” which is listed in sys.path. Since the application folder structure is fixed, we can use os.path to get the full path of the module we wish to import.
Now, why would you use the walrus operator?
Otherwise step is positive, and the lower bound will be zero and the upper bound (which we go up to but not including) the length of the sliced list. Thus a negative slice will change the defaults for start and stop! But you can pass in a negative integer, and the list (or most other standard sliceables) will be sliced from the end to the beginning. The above code is a definition of a decorator that decorates a function.function_decorator is the name of the decorator. If you are referring to some code in a python notebook which is using Numpy library, then @ operator means Matrix Multiplication.
In such a situation, changing the import statement in a to import mylib.bwill not work since a and b are both in mylib. And I want to import a.py to foo. Now, I want to import b.py into a.py.
How slicing in Python works
Instead, run your file as a module and add a __init__.py in your some_folder directory. Only the folder application/app2/some_folder is added to the path (not the base directory that you’re executing the command in). My solution for people who have all the necessary __init__.py in the package, but import still doesn’t work. You can instead use a tool that will add a given absolute/relative path to sys.path while making sure the path is valid and in the correct format.
