2 Points Suppose that the file out.txt is 48 lines long. If we executed the lines of code below from a Python file in the same folder as out.txt, how many lines long would out.txt be after the program finished executing? 1 2 48 49 A Runtime Error would occur Q4 CSV files 3 Points file = open ('info.csv', ' r ' ) data = file, readiines () file, close( ) total = 0 for row in datat row = row.strip() entries = row. Bplit (,) for val in entries: Suppose that info.csv is a CSV (comma-separated values) file, where the rows and columns of the CSV file represent the rows and columns of a matrix of integers (there's no header row/column). Fill in the blank in the program above with a single line of code, such that by the end of the program, the variable total represents the sum of all the integers in the CSV file..
