这里介绍一下python
中n次方运算的四种书写形式,代码如下:
# -*- coding:utf-8 -*-

software: PyCharm
Description:
"""
import numpy as np
class PythonStudy:
@staticmethod
def powerAlgorithm():
# basic python method
x = 2
x1 = x ** 2
print(f"The value of x1 is {x1}")
x2 = pow(x, 2)
print(f"The value of x2 is {x2}")
x3 = x.__pow__(2)
print(f"The value of x3 is {x3}")
# numpy method
x4 = np.power(x, 2)
print(f"The value of x4 is {x4}")
if __name__ == '__main__':
main = PythonStudy()
main.powerAlgorithm()
"""
输出结果:
The value of x1 is 4
The value of x2 is 4
The value of x3 is 4
The value of x4 is 4
"""
可以看到,四种方法均成功输出了我们想要的平方运算。
码字不易,如果大家觉得有用,请高抬贵手给一个赞让我上推荐让更多的人看到吧~
