When working with Julia, you may come across situations where you need to find the equivalent of Python’s help function. The help function in Python provides information about a specific object or module, including its docstring and available methods. In Julia, there are multiple ways to achieve similar functionality.
Option 1: Using the ? operator
Julia provides a built-in ? operator that can be used to get help on a specific function or object. To use this operator, simply append a ? to the end of the function or object name.
?function_name
This will display the help information in the REPL (Read-Eval-Print Loop) or the Julia IDE you are using. The help information includes the docstring and available methods for the specified function or object.
Option 2: Using the @doc macro
Another way to get help in Julia is by using the @doc macro. The @doc macro allows you to access the documentation of a specific function or object.
@doc function_name
This will display the documentation of the specified function or object in the REPL or Julia IDE. The documentation includes the docstring and additional information about the function or object.
Option 3: Using the Julia documentation website
If you prefer a more comprehensive and detailed documentation, you can visit the official Julia documentation website. The website provides extensive documentation on various topics, including the standard library, packages, and language features.
To find the equivalent of Python’s help for a specific function or object, you can search for it on the Julia documentation website. The search results will provide detailed information about the function or object, including its usage, arguments, and examples.
Overall, the best option depends on your preference and the level of detail you require. If you prefer a quick and concise help, using the ? operator or the @doc macro within the Julia environment is a good choice. However, if you need more comprehensive documentation, referring to the Julia documentation website is recommended.
