Python programming: From introductory to practical reading notes (i)

tuples:python values that cannot be modified are called immutable, and immutable lists are called tuples.

Such as:

dimensions= (200,50) print (Dimensions[0]) print (dimensions[1])

list: consists of a series of elements arranged in a particular order.

bicycles=[' Trek ', ' Cannondale ', ' Redline ']print (bicycles)

function: a code block with a name that is used to accomplish specific work.

def greet_user (username):    print ("Hello," + username.title () + "!")

　　Pass arguments : positional arguments and keyword arguments

　　　　positional arguments: The order of the arguments based on the argument.

　　　　keyword Argument : is the name----value pair that is passed to the function. You associate the name and value directly in the argument.

class : Method _init_ () is a special method that Python will run automatically whenever an instance of the class is created.

Class Dog ():    def _init_ (self, Name, age):        self.name = name         Self.age = Age        def sit (self):        print ( Self.name.title () + "is now sitting.")    def roll_over (self):                print (Self.name.tilte () + "rolled over!")
