python 立方根
时间: 2023-11-30 17:43:04 浏览: 158
Python提供了多种方法来求立方根,以下是其中的三种方法:
1. 使用幂运算符
```python
num = 8
cube_root = num ** (1/3)
print(cube_root) # 输出:2.0
```
2. 使用math模块
```python
import math
num = 8
cube_root = math.pow(num, 1/3)
print(cube_root) # 输出:2.0
```
3. 使用NumPy模块
```python
import numpy as np
num = 8
cube_root = np.cbrt(num)
print(cube_root) # 输出:2.0
```

python 立方根函数
Python中可以使用math库中的cbrt()函数来计算立方根。这个函数接受一个参数,即需要计算立方根的数字。下面是一个示例代码:
import math
x = 125
y = math.cbrt(x)
print(y)
这段代码中,我们导入了math库,并定义了一个变量x,然后使用math.cbrt()函数计算了x的立方根,并将结果打印出来。输出结果将是5.0。<span class="em">1</span><span class="em">2</span><span class="em">3</span>

python立方根 画图
以下是Python求立方根和画图的例子:
1. Python求立方根
```python
import math
x = 8
cube_root = math.pow(x, 1/3)
print("The cube root of", x, "is", cube_root) # 输出:The cube root of 8 is 2.0
```
2. 画图
```python
import numpy as np
import matplotlib.pyplot as plt
x = np.arange(0.0, 2.0*np.pi, 0.01)
y = np.cos(x)**3
fig, ax = plt.subplots()
ax.plot(x, y, linewidth=2)
ax.set(xlabel='x', ylabel='y',
title='Cube Root Graph')
ax.grid()
plt.show()
```
