今天我们来进入一个新的话题“Function”。 其实这个话题并不陌生,例如我们之前的学过的type( )、print( )、str( )、int( )等等命令都是不同的Function. 在进行一些基础的数据数理时,这些已经在Python中设置好的Functions,可以帮助我们更容易地达成目标。 举个例子,假设我们想找出身高数据的最大值,只需要输入max...

Functions are everywhere in PythonPython includes about 70 built-in functions, and most objects in Python have one or more methods.We'll see more functions and methods as we dive deeper into Python later, and eventually we'll create our own functions....

【实参,actual parameter】While using those methods, values passed to those variables are called arguments. 再换个说法: 形参(parameter)通常在函数创建时被定义,决定了什么实参(argument)可以被接收。 实参(argument)用来传递给函数。 函数代码执行往往会因实参(argument)不同而结果不同。 1.3 函数功能 打工...
The math module also comes with several functions, or methods. 让我们试试平方根函数。 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...
这个BIF(Built-in functions)有三个参数,其中用中括号括起来的两个表示这两个参数是可选的。 step=1 表示第三个参数的默认值是1。 range 这个BIF的作用是生成一个从start参数的值开始到stop参数的值结束的数字序列,该序列包含start的值但不包含stop的值。 【例子】 for i in range(2, 9): # 不包含9 pr...
The decorator tells the built-in default metaclasstype(the class of a class, cf.this question) to not create bound methods formethod_two. Now,you can invoke static method both on an instance or on the class directly: >>>a_test =Test()>>>a_test.method_one()Called method_one>>>a_te...

Programmers moving to Python from Java are often tempted to write lots of getter and setter methods, rather than use properties. We might want to find those methods. Using the member predicate Function.getName(), we can list all of the getter functions in a database: Tip Instead of ...
