Im trying to make a function the reads in a file and store the numerical values of each column in lists for computation however when i run this line of code it gives me the message "none" even though I have the file saved on my computer and have used the exact same line of code in a previous program without defining it as a variable which works perfectly dont know what exact I'm doing wrong here

def readCSVFile(fileName): openFile = open(fileName) headings = openFile.readline().s headingsLength = (len(headi observations = 11 all empty lists columns = ] values = [] for header in headings: observations.append (1) for row in openFile: Columns - row.strip().split(",") values.append (columns) for nun in range(headingsLength): observations (num).append (float(columns [num])) #observations (0)=Max Temp, observations (1)-Min Te 45 print (readCSVFile("reducedweather.csv")) In [98]: runfile('/Users/matthewlaluk/Downloads/untitled2.py', wdir='/Users/ matthewlaluk/Downloads') None In 1991: nloads * reducedwease...
