Write a Python program that calculates the area of a circle based on the radius entered by the user.Python: Area of a Circle In geometry, the area enclosed by a circle of radius r is πr2. Here the Greek letter π represents a constant, approximately equal to 3.14159, which is equal ...

当代码出现有规律的重复的时候,你就需要当心了,每次写3.14 * x * x不仅很麻烦,而且,如果要把3.14改成3.14159265359的时候,得全部替换。 有了函数,我们就不再每次写s = 3.14 * x * x,而是写成更有意义的函数调用 s = area_of_circle(x),而函数 area_of_circle 本身只需要写一次,就可以多次调用。 抽象...

三角形对象从其父类shape继承的name、numberOfSides和findArea部分(尽管这些部分有不同的值和实现)。如果一个对象从shape类继承,它也将继承那些部分。它不一定用那些零件,但它有。它可能有额外的部分(例如,circle对象可能有一个radius值),但是它总是有那些部分。
Work through the definition of @timer line by line. Make sure you understand how it works. Don’t worry if you don’t get everything, though. Decorators are advanced beings. Try to sleep on it or make a drawing of the program flow. Note: The @timer decorator is great if you just ...
# Creating an instance of the Circle class my_circle = Circle(radius=5) # Accessing properties using the @property decorator print("Radius:", my_circle.radius) print("Area:", my_circle.area) 输出: 复制 Radius: 5 Area: 78.5 在上面的实现中,类“Circle”有一个属性“radius”。我们使用@prop...
