Python 尝试输入时发生UFuncTypeError

当我尝试输入值时，我得到了一个（如下）错误，但当我静态地分配它们时，我不知道为什么

我正在尝试输入inn和out的值。我得到了错误代码，但我真的不知道如何修复它

---

错误代码：

import numpy as np
import matplotlib.pyplot as plt

inn=.95
out=1.37

n, radii = 50, [inn, out]

theta = np.linspace(0, 2*np.pi, n, endpoint=True)
xs = np.outer(radii, np.cos(theta))
ys = np.outer(radii, np.sin(theta))

# in order to have a closed area, the circles
# should be traversed in opposite directions
xs[1,:] = xs[1,::-1]
ys[1,:] = ys[1,::-1]

fig, ax = plt.subplots()

ax = plt.subplot(111, aspect='equal')
ax.fill(np.ravel(xs), np.ravel(ys),color='pink')

star = plt.Circle((0, 0), .25, color='yellow')
earthorbit = plt.Circle((0, 0), 1, color='black', fill=False,linestyle='-',linewidth=2)
inner = plt.Circle((0, 0), inn, color='red', fill=False,linestyle='--',linewidth=2)
outer = plt.Circle((0, 0), out, color='blue', fill=False,linestyle='--',linewidth=2)

ax.add_artist(earthorbit)
ax.add_artist(inner)
ax.add_artist(outer)
ax.set_facecolor('black')
ax.add_artist(star)

plt.show()

import numpy as np
import matplotlib.pyplot as plt

inn=input("Enter inner radial value (in AU): ")
out=input("Enter inner radial value (in AU): ")


n, radii = 50, [inn, out]

theta = np.linspace(0, 2*np.pi, n, endpoint=True)
xs = np.outer(radii, np.cos(theta))
ys = np.outer(radii, np.sin(theta))

# in order to have a closed area, the circles
# should be traversed in opposite directions
xs[1,:] = xs[1,::-1]
ys[1,:] = ys[1,::-1]

fig, ax = plt.subplots()

ax = plt.subplot(111, aspect='equal')
ax.fill(np.ravel(xs), np.ravel(ys),color='pink')

star = plt.Circle((0, 0), .25, color='yellow')
earthorbit = plt.Circle((0, 0), 1, color='black', fill=False,linestyle='-',linewidth=2)
inner = plt.Circle((0, 0), inn, color='red', fill=False,linestyle='--',linewidth=2)
outer = plt.Circle((0, 0), out, color='blue', fill=False,linestyle='--',linewidth=2)

ax.add_artist(earthorbit)
ax.add_artist(inner)
ax.add_artist(outer)
ax.set_facecolor('black')
ax.add_artist(star)

plt.show()

您写入输入的内容将保存为

字符串

值，但我认为您需要

浮点

，请尝试以下操作：

inn=float(input("Enter inner radial value (in AU): "))

---

它的意思是不能将两个字符串数组相乘检查

半径

和

θ

。它们真的是数字，还是字符串？啊，它们是字符串，不是吗。我没有这样想。当我这样做时，我得到：文件“C:\Users\sveng\Desktop\HabitableZone.py”，第4行，在inn=int（输入（“输入内径向值（在AU中）：”）值错误：int（）的文本无效，基数为10:'.95'，然后：inn=float（输入（“输入内径向值（在AU中）：”）

inn=float(input("Enter inner radial value (in AU): "))
