# Python `help()` function

In Python, the **`help()` function** is used to get information or details about a function, class, keyword, module, and so on.

#               
## Syntax
```
help(object)
```

         
## Parameter values
- **Object**: This parameter value represents the object that is passed to the `help()` function.

> Note: The interactive help utility starts up on the console if the `help()` function is used without an argument.

Suppose we have a Python code with a function and we need information on what that function does. In this case, we will find the `help()` function to be quite useful.

Let's look at the code example given below to better understand the `help()` function.

     
## Examples 





#create my_func() function
def my_func(a,b):
  result = a * (b **3)
  return result
 
print("Using help() to get info on my_func():")
help(my_func)

## Explanation

- Lines 2–4: We create a function called `my_func` that takes two parameters. Next, we assign the computation result to a new variable called `result`. Finally, the function returns a value.

- Line 6: We use the `print()` statement to display a message.

- Line 7: We use the `help()` function to obtain details about the `my_func()` function. 

Another example involves the use of the `help()` function to get information on a certain keyword:


# Using help() to get info on list keyword
help(list)

> Note: The object parameter for the `help()` function is optional.
