Hello I need help with following python problem. I don't know why Im keep getting errors. Please refer 1b to solve the problem. Thank you! 1b) Create a function that converts string labels to numerical labelsFunction name: convert_labelThe function should do the following:• take two parameters label and direction• if direction is 'tonumber',· and if the input label is "pos" return 1.0· and if the input label is "neg" return 0.0• otherwise, return the input label as is• if direction is 'tolabel'and if the input label is 1.0 return "pos"· and if the input label is 0.0 return "neg"otherwise, return the label as is1 def convert_label(label, direction):"tonumber":if directionif 'pos' in label:return 1.0elif 'neg' in label:return 0.0return labelif direction"tolabel":if '1.0' in label:return 'pos'elif '0,0' in label:return 'neg'else:101112131415return label1 assert convert_label1 assert callable(convert_label)H N 3 4567 ∞0 o d NM Convert all labels in MR_df["label"] to numerical labels, using the convert_label function. Be sure to specify theappropriate argument to the direction parameter.Save them as a new column named "Y" in MR_df.1 # YOUR CODE HERE2 df['MR_df']=[convert_label(x,'tonumber') for Y in df[MR_df]]NameErrorTraceback (most recent call last)/tmp/ipykernel_456/4234017543.py in 1 # YOUR CODE HERE-> 2 df['MR_df']=[convert_label(x, 'tonumber')for Y in df [MR_df]]NameError: name 'df' is not defined1assert sorted (set (MR_df['Y']))[0., 1.]Traceback (most recent call last)KeyError/opt/conda/lib/python3.9/site-packages/pandas/core/indexes/base.py in get_loc(self, key, method, tolerance)3360try:return self._engine.get_loc(casted_key)except KeyError as err:-> 33613362/opt/conda/lib/python3.9/site-packages/pandas/_libs/index.pyx in pandas._libs.index.IndexEngine.get_loc( )/opt/conda/lib/python3.9/site-packages/pandas/_libs/index.pyx in pandas._libs.index.IndexEngine.get_loc()pandas/_libs/hashtable_class_helper.pxi in pandas._libs.hashtable.Py0bjectHashTable.get_item()pandas/_libs/hashtable_class_helper.pxi in pandas. libs.hashtable.Py0bjectHashTable.get_item( )КeyError: 'Y"The above exception was the direct cause of the following exception:КeyError/tmp/ipykernel_456/2394443215.py in ----> 1 assert sorted (set (MR_df['Y'])).Traceback (most recent call last)[0., 1.]

The error in your code is occurring because of following reasons: The code is using 'MR_df' as the column name for 'df'. But as per the question description, MR_df is the data frame, not the column name. In the list comprehension, when x is being used as the parameter to the function, then that should also be the iterable parameter after the 'for' keyword instead of Y. The name of the new column should be Y. The corrected code addressing all these issues to get the required result is given in the next step.CORRECTED CODE:- MR_df['Y'] = [convert_label(x, 'tonumber') for x in MR_df["label"]]CODE SCREENSHOT:-TEST SCREENSHOT:- As we can see, now the above code and the assertion did not throw any error as they run successfuly
