bookhelp()

While IDEs can provide hints for functions, these hints may not be available in environments such as Jupyter Notebook or console interpreter. To get information about a function or object, you can use the help() function:


              
123456

            
def add(a: int, b: int) -> int:
    """This function receives two integer arguments and returns its sum."""
    return a + b


help(add)
copy

Everything was clear?

How can we improve it?
