Question

我正在通过Jupyter Notebook学习Python。我想从一组数据中计算出x̄，然后以字符串形式打印出该值。如何获取变量x̄？

我尝试使用$ \ bar x $和$ \ overline {x} $，但都返回语法错误

我想念图书馆吗？我有

from matplotlib import pyplot as plt
import numpy as np

f = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print($\bar x$ + f" = {np.average(f)}")

  File "<ipython-input-128-0e2d9b6ee635>", line 2
    print($\bar x$ + f" = {np.average(f)}")
          ^
SyntaxError: invalid syntax

f = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print($\overline {x}$ + f" = {np.average(f)}")

  File "<ipython-input-129-2807d1e5e7ae>", line 2
    print($\overline {x}$ + f" = {np.average(f)}")
          ^
SyntaxError: invalid syntax

改为使用此：

import numpy as np
f = [1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
print(f"{np.average(f)}")

使用$时出现SyntaxError
