The data items are strings such as '4.3' but some of them are empty '' and must be ignored. return a list of floats of all the strings that are valid numbers ''' # TODO: return list comprehension return

Problem 2:

This problem is related to the ProcessCrimeRates2.py code. def getStatesWithRate(alldata, startpos, num): ''' alldata is all of the data in a list of lists of strings startpos is the (row,column) position of the category, row+1 would be where the numbers start. return a list of states (from column 0) that have num in them in column 'column' num is a float ''' states = [] # TODO: finish body of loop for row in range(startpos[0]+1,len(alldata)): return states

Problem 3:

Which of the following are equivalent to s^t for sets s and t (more than one is possible)?

  1. (s-t) | (t-s)

  2. (s|t) - (s&t)
