“类型错误:‘str’对象不可调用"；使用 Jupyter Notebook 时出错 [英] "TypeError: 'str' object is not callable" error while using Jupyter Notebook

问题描述

我尝试使用 matplotlib 中的 pyplot 绘制图形，一切正常，直到我尝试添加标题.

I tried to plot a graph using pyplot from matplotlib and everything went fine until I tried to add the title.

from matplotlib import pyplot as plt
a = [1, 4, 8]
b = [1, 9, 18]
plt.plot(a, b)
plt.title("Title")
plt.xlabel("x")
plt.ylabel("y")
plt.show()

除标题外，代码运行正常，显示错误如下:

The code works fine except the title, from which an error is displayed as follows:

        TypeError                                 Traceback (most recent call last)
    <ipython-input-25-a1c519e5c0a1> in <module>
          4 plt.xlabel("X")
          5 plt.ylabel("Y")
    ----> 6 plt.title("title")
          7 plt.show()

TypeError: 'str' object is not callable

顺便说一句，我正在使用 Jupyter notebook 运行它

BTW, I am running this using Jupyter notebook

推荐答案

我在 Jupyter 笔记本上遇到过两次这个错误.重新启动您的 anaconda 或更好:从内核选项卡重新启动并运行所有.这应该有效

I had this error twice on the Jupyter notebook. Restart your anaconda or better: from the kernel tab restart and run all. This should work
