Step 1This error typically occurs when you are trying to use the `append()` function on a pandas DataFrame object that does not have the attribute 'append'.
This can happen if you have an older version of pandas that does not support the `append()` function, or if the DataFrame object you are trying to append to is not a pandas DataFrame. To resolve this error, you can try updating your pandas library to the latest version using pip: ```python pip install --upgrade pandas ``` If updating pandas does not resolve the issue, you can try checking the type of the object you are trying to append to, to make sure it is a pandas DataFrame. You can do this using the `type()` function in Python: ```python if type(2$) is not pandas. DataFrame: raise ValueError(2$) ``` If the object is not a pandas DataFrame, you can convert it to one using the `DataFrame()` constructor: ```python df = pandas. DataFrame(2$) ``` Once you have confirmed that the object is a pandas DataFrame, you can try appending to it again using the `append()` function. If you are appending multiple rows at once, make sure they are in a list or array: ```python df = df.append(2$) ``` or ```python df = df.append(2$), ignore_index=True) ``` If you are still having trouble with the `append()` function, you can try using the `concat()` function instead: ```python df = pandas.concat(2$)], ignore_index=True) ``` This will concatenate the new rows onto the existing DataFrame, effectively appending them to the end.
