List of lists (not just list) in Python
Question: I want to make a list of lists in python.

My code is below.

    
    
    import csv
    f = open('agGDPpct.csv','r')
    inputfile = csv.DictReader(f)
    
    list = []
    
    next(f) ##Skip first line (column headers)
    
    for line in f:
        array = line.rstrip().split(",")
        list.append(array[1])
        list.append(array[0])
        list.append(array[53])
        list.append(array[54])
        list.append(array[55])
        list.append(array[56])
        list.append(array[57])
    print list
    

I'm pulling only select columns from every row. My code pops this all into one
list, as such:

    
    
    ['ABW', 'Aruba', '0.506252445', '0.498384331', '0.512418427', '', '', 'AND', 'Andorra', '', '', '', '', '', 'AFG', 'Afghanistan', '30.20560247', '27.09154001', '24.50744042', '24.60324707', '23.96716227'...]
    

But what I want is a list in which each row is its own list:
`[[a,b,c][d,e,f][g,h,i]...]` Any tips?


Answer: You are almost there. Make all your desired inputs into a list before
appending. Try this:

    
    
    import csv 
    with open('agGDPpct.csv','r') as f:
      inputfile = csv.DictReader(f)
      list = []
    
      for line in inputfile: 
        list.append([line[1], line[0], line[53], line[54], line[55], line[56], line[57]])
    print list
