The issue here is that you are trying to access the value of column ‘0’ in row ‘12’, which is not a valid operation when using iloc. The iloc method requires two indices, one for rows and one for columns. When using this method with a single index (in your case, 12), it returns a Series containing all values for that particular row. To fix the issue, you can access only the first column of each row by using iloc[:,0], which will return a Series containing the first value in each row.
