为什么只有3个，python为什么说有4个参数？

Question

[我正在使用gspread应用编写Tkinter。我相信与电子表格的连接是正确的，因为我可以从中读取数据。我正在使用python 2.7.15和gspread 0.6.2。我得到了错误。如果我在函数调用的末尾忽略了“ RAW”参数，则不会再出现任何错误，但不会将任何内容写入电子表格。

Exception in Tkinter callback
Traceback (most recent call last):
  File "/usr/lib/python2.7/lib-tk/Tkinter.py", line 1550, in __call__
    return self.func(*args)
  File "app.py", line 22, in clicked
    sheet.insert_row(insertRow,index,'RAW')
TypeError: insert_row() takes at most 3 arguments (4 given)

您正在使用旧版本的gspread。在您使用的版本中，insert_row的定义如下所示：

def insert_row(self, values, index=1):

注意如何只接受三个参数：self（在实例上调用时自动传递）以及values和index。它不接受任何其他参数。您需要删除RAW参数，代码才能与此版本的库一起使用。
