Circle Area CalculatorWrite 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 ...
# Program to find Area of Circle using Diameter# Taking diameter from userdiameter =float(input("Enter the diameter of circle : "))# Taking diameter measure unit from userunit =input("Enter the measure unit of diameter (e.g. in, cm) : ")# Finding area of a circle using ( A = 1/...
类还可包含类属性和静态方法: classCircle:pi=3.14159# 类属性 @staticmethod defarea(radius):returnCircle.pi*radius**2print(Circle.area(5))# 输出78.53975 结语 最后曾曾给大家整理了一些Python从入门到实战的学习资料合集,都是曾曾曾经学习时在网上收集整理来的,获取方式我放到文末了,需要的粉丝朋友可以自取!
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。
#CaCircleArea.py r = 25 area = 3.1515 * r * r print(area) print("{:.2f}".format(area)) 结果输出 绘制五角星: #DrawStar.py from turtle import * color('red','red') begin_fill() for i in range(5): fd(200) rt(144)
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 ...
# Getter method for the radius. return self._radius @property def area(self): # Getter method for the area. return 3.14 * self._radius**2 # Creating an instance of the Circle class my_circle = Circle(radius=5) # Accessing properties using the @property decorator ...
