解决’tuple’ object is not callable的报错-python变量命名错误

1. 变量命名要避python内置函数的名字初学python，很容易犯这样的错误，即直接用set, list, tuple, dict, str, int, complex, float等作为变量名。这样会导致这些内置函数：set(), list(), tuple()等等无法执行。例如下例，使用tuple作为变量名，再执行tuple()语句时，会报错 ‘tuple’ object is not callable 原因如下：作用域优先级：在执行python代码时，你用的每一个变量，都需要寻找，寻找的过程遵循一定的优先级规则，下面按优先级从大到小排序局部作用域嵌套作用域全局作用域

The error message "'tuple' object has no attribute 'savefig'" is usually raised when you are trying to call the `savefig` method on a tuple object. This means that the variable you are trying to call `savefig` on is not an instance of a Matplotlib figure or Axes object. To fix this error, you should check the data type of the variable you are trying to call `savefig` on. Make sure it is an instance of a Matplotlib figure or Axes object before calling the `savefig` method. For example, if you are trying to save a figure to a file, you might have code like this: ``` fig, ax = plt.subplots() # add some plots to the axes ax.plot(x, y) # save the figure to a file fig.savefig('myplot.png') ``` If you accidentally use a tuple instead of a figure object, you might get the error message "'tuple' object has no attribute 'savefig'". For example: ``` fig, ax = plt.subplots() # add some plots to the axes ax.plot(x, y) # accidentally assign a tuple to fig instead of a figure object fig = (fig, ax) # try to save the figure to a file fig.savefig('myplot.png') # raises "'tuple' object has no attribute 'savefig'" ``` To fix this error, make sure you are assigning the figure object to `fig`, not a tuple.
