设计需求： Customer SQL Test: I will type an SQL Query into the test box which you will execute and print the results in the Python IDLE shell. Distinct Values: I will provide a table name and a column name in the form Tablename,ColumnName (e.g. Soups,Type) You must determine the number of unique values for the ColumnName in the TableName (e.g. How many unique values for the column type are there in the Soups table). Once you are finished counting, put a message “xx unique values” in the line edit box below the button.
