Q2 Suppose we want to process the column names so that the columns whose names are of the form XXXon- get shortened to just , and the rest remain as is. This will proceed in three steps: if the name 1. Write a lambda function, assigned to short_col that, given a string name of a column, yields the part after a contains a - . 2. Assign to newcols a list comprehension that applies short_col to the columns attribute of indicatorso 3. Change indicators so that its columns are based on newcols. Print a prefix of the first five rows of the changed indicatorso. # Student Experimentation Cell # Solution Cell result = io.StringIO() with redirect_stdout (result): # YOUR CODE HERE raise NotImplementedError() print(result.getvalue()) # Testing Cell assert str(type (short_col)) == "" assert short_col('code_country') == 'code_country' assert short_col('INDO3-life') =='life
