Hello,

For "Data visualization(Pyhton3), I am getting the following errors:(please see screenshot).

My code:

# function to check commas def checkCommas(dataPoint): # to check if there is comma or not if ',' not in dataPoint: # Display an error message "No comma in string" print('Error: No comma in string.') return False # to check if the datapoint has more than one comma elif dataPoint.count(",") > 1: # Display an error message "Too many commas in input" print('Error: Too many commas in input.') return False # to check if there an integer after comma else: # find index. index = dataPoint.find(",") # split the datapoint name = dataPoint.split(",")[0] integer = (dataPoint.split(",")[1]).strip() # to check if the number is integer or not. if not (integer.isdigit()): # Display an error message "Comma not followed by an integer" print('Error: Comma not followed by an integer.') return False else: return True

# Prompt the user to enter the header for column 1 of a table header2 = input(' Enter the column 2 header: ') print("You entered: " + header2)

# Prompt the user to enter data points dataPoint = input(" Enter a data point (-1 to stop input): ") while dataPoint != "-1": # Call to the function to check for commas commas = checkCommas(dataPoint) #if there is only one comma and data entered is correct,split the data if commas: name = dataPoint.split(",")[0] integer = int((dataPoint.split(",")[1]).strip()) # Print the datapoint on console print("Data string: " + name) print("Data integer: " + str(integer)) # Store data in the list nameList.append(name) numberList.append(integer) # Prompt the user to enter data points dataPoint = input(" Enter a data point (-1 to stop input): ")

# to output the information in a formatted table, call the function table() table(title, header1, header2, nameList, numberList) # to output the information as a formatted histogram, call the function histogram() histogram(nameList, numberList)

# Call the main function. main()
