05:47Of course, you don’t have to do this in Python because Python allows you toreturn multiple values.So you can, in a single return statement,return the personalized greetingand the incremented value of how many times the function has been calledpacked in a tuple. ...
Remember also that you can define one or more function parameters for your UDF. You’ll learn more about this when you tackle the Function Arguments section. Additionally, you can or can not return one or multiple values as a result of your function. Learn Python From Scratch Master Python ...
def greet(name, counter): # Return multiple values return f"Hi, {name}!", counter + 1 counter = 0 ... # Later, reassign each return value by unpacking. greeting, counter = greet("Alice", counter) When calling a function that returns multiple values, you can assign multiple variables...

在本章中,我们将讨论数学形态学和形态学图像处理。形态图像处理是与图像中特征的形状或形态相关的非线性操作的集合。这些操作特别适合于二值图像的处理(其中像素表示为 0 或 1,并且根据惯例,对象的前景=1 或白色,背景=0 或黑色),尽管它可以扩展到灰度图像。 在形态学运算中,使用结构元素(小模板图像)探测输入图像...
Let’s try out the square root function. 要使用它,我键入math.sqrt,输入参数是我希望平方根取的数字。 To use that, I type math.sqrt and the input argument is the number that I want the square root to be taken of. 在本例中,我要求Python返回10的平方根值。 So in this case, I’ve aske...
