![]() Using loads allows you to convert your string, in this instance, into a dictionary. With the load function, it’s assuming you have a JSON file already setup. Now you might be wondering why we wouldn’t use json.load. All you have to do is enter import json at the top of your script.įor this example, we’ll be using the json.loads method, which is the equivalent of reading the file, or in this instance our soon-to-be dictionary. Just like with AST, JSON is a built-in module for Python, which means you’ll never need to install it. It does use JavaScript syntax, but it’s used for more than just JavaScript. JSON stands for JavaScript Object Notation. This is the most common solution to the problem-compare this article to learn more!īut if you’re looking for something different, then we have another option for you to consider. If it doesn’t, then you might want to check your code again. Doing so will show that you have a class that is a dictionary. If you need more convincing, then create a print statement. If it helps any, you can always try to create a little comparison between the two. Using this method allows you to convert your string into a dictionary. d = ast.literal_eval(basketball)įor this instance, you would use it like this. This works for all Python structures, including dictionaries. You can evaluate the string that contains a literal or container display. You’ll specifically need to use literal_eval (or ast.literal_eval). The library assists the Python interpreter in analyzing the Abstract Syntax Tree-what you may call the “ grammar of your code“. Just import it at the top of your code using import ast. There’s no need for you to install AST because it’s just there for you. Method 2: ASTĪST is another built-in module for Python. And there’s one easy alternative that can get you where you want. ![]() The fact is, there are better options for you to use. The result is stored in the variable d.Īs you start working with Python more, you need to be careful not to use options like eval(). The eval() function evaluates the string and understands that it is a dictionary. Even with safeguards you put in, it might not be enough. Ned Batchelder covers this topic well in his blog. ![]() You should never trust code from the internet that’s packed into an eval() or exec() function! However, using the eval() function is dangerous because it can execute all kinds of Python code on your operating system like removing or creating files. Python’s eval function is built-in and it can seem like a good idea for you to use. Let’s start with the one you shouldn’t use. Are all three variables of type dictionary? Instead, there are a couple of ways you can do it and one big NO-NO that you shouldn’t use (Method 1):Įxercise: Run the code. You could do it the long way by typing everything, but that would involve making some adjustments. Solution Overview: You can do so by converting it to a dictionary. How to change it from a string to a dictionary? It looks like a dictionary, but it is not. You have LeBron on there, Harden, Steph, and all the talented guys. Problem: How to convert the str representation of a dict into a dict?Įxample: Let’s create a list of NBA players. ![]()
