とかすると、指定関数の説明が見れる。

print(...)
    print(value, ..., sep=' ', end='\n', file=sys.stdout, flush=False)
    
    Prints the values to a stream, or to sys.stdout by default.
    Optional keyword arguments:
    file:  a file-like object (stream); defaults to the current sys.stdout.
    sep:   string inserted between values, default a space.
    end:   string appended after the last value, default a newline.
    flush: whether to forcibly flush the stream.

自作関数の場合は、以下みたいな感じで、関数化に """ で説明書く

def least_difference(a, b, c):
    """Return the smallest difference between any two numbers
    among a, b and c.
    
    >>> least_difference(1, 5, -5)
    4
    """
    diff1 = abs(a - b)
    diff2 = abs(b - c)
    diff3 = abs(a - c)
    return min(diff1, diff2, diff3)
