Why does python say there are 4 arguments when there are only 3?

Question

I'm writing a Tkinter with gspread app. I believe the connections to the spreadsheets are made properly because i can read data off it. I'm using python 2.7.15 and gspread 0.6.2. I get the error. If i leave out the 'RAW' argument at the end of the function call, I no longer get any errors, but nothing gets written to the spreadsheet.

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)

You're using an old version of gspread. In the version you're using the definition of insert_row looks like this:

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

Notice how it takes only three arguments: self (automatically passed when called on an instance), along with values and index . It doesn't accept any other parameters. You need to remove the RAW argument for your code to work with this version of the library.
