Python Code:# Import the 'pi' constant from the 'math' module to calculate the area of a circle from math import pi # Prompt the user to input the radius of the circle r = float(input("Input the radius of the circle : ")) # Calculate the area of the circle using the formula: ...
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...

Pythoncirclearea函数 python circle函数参数 3.2 参数列表与返回值 对于代码清单3-1中实现的CalCircleArea函数,只能进行半径为3的圆面积的计算,而无法用于计算其他半径的圆的面积。另外,在计算圆面积后,只是通过print函数将计算结果输出到屏幕上,而无法使用该计算结果再去做其他运算。这里将要介绍的参数列表与返回值...

Write a function to compute the area of a circle rounded off to two decimal places. The area of a circle is calculated using the formulapi * radius^2. For example, ifradius = 5, the expected output is78.54. calculate_area(radius):...
To calculate the tenth Fibonacci number, you should only need to calculate the preceding Fibonacci numbers, but this implementation somehow needs a whopping 177 calculations. It gets worse quickly: 21,891 calculations are needed for fibonacci(20) and almost 2.7 million calculations for the thirtieth...
