The said code calculates the area of a circle based on the radius entered by the user. The code uses the "math" module's pi constant and the "input" function to get the radius from the user, then it uses the formula to calculate the area of the circle.The first line from math impo...
Beginning Python - Calculating Area of a Circle首先,我使用的是pyscripter ver。2.6.0.0 x64,带python版本。3.3.0 x64 我正在上一门关于Python的入门课程,我完全被难住了。我被问到这个问题: 编写一个名为calculateArea的函数。函数应采用表示圆半径的参数,并返回圆的面积。编写一个程序,要求用户输入圈数。
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...
提示 在代码清单3-2中,第1～3行是CalCircleArea函数的定义,其只有一个参数r,表示要计算面积的圆的半径。第4～6行是CalRectArea函数的定义,其有两个参数a和b(多个形参需要用逗号分隔),表示要计算面积的长方形的两个边长。
