Python基础——PyCharm版本——第六章、函数function(2)

数据类型转换Python内置的常用函数还包括数据类型转换函数，比如int()函数可以把其他数据类型转换为整数：定义函数在Python中，定义一个函数要使用def语句，依次写出函数名、括号、括号中的参数和冒号:，然后，在缩进块中编写函数体，函数的返回值用return语句返回。我们以自定义一个求绝对值的my_abs函数为例：def my_abs(x): if x >= 0: ...

Python基础——PyCharm版本——第六章、函数function(1)

函数function我们知道圆的面积计算公式为：S = πr2当我们知道半径r的值时，就可以根据公式计算出面积。假设我们需要计算3个不同大小的圆的面积：r1 = 12.34 r2 = 9.08 r3 = 73.1 s1 = 3.14 * r1 * r1 s2 = 3.14 * r2 * r2 s3 = 3.14 * r3 * r3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 * ....
