从CSV创建列表

Question

我正在将CSV导入python，并希望创建列表，这些列表是CSV文件的当前列。这些列表将包含每一列下的所有数据。

我已经尝试过将随该问题发布的代码。

import os
import csv
import numpy as np
import pandas as pd

os.chdir('My Drive Information HERE')
os.getcwd()

infile = 'diamonds.csv'

# create new empty list
diamondList = []

with open(infile, 'rU') as csvfile:
    # the csv file reader returns a list of the csv items on each line
    ALReader = csv.reader(csvfile,  dialect='excel', delimiter='\t')

    # from each line, a list of row items, put each element in a dictionary
    #   with a key representing the data
    for line in ALReader:
      # skip lines without data
      if line[0] == '':
          continue
      else:
          try:
            # create a dictionary for each player
            diamonds = {}
            # add each piece of data under a key representing that data
            diamonds['diamond carat'] = line[0]
            diamonds['diamond cut'] = line[1]
            diamonds['diamond color'] = line[2]
            diamonds['diamond clarity'] = line[3]
            diamonds['diamond price'] = line[4]

            # add this player to the list
            diamondList.append(diamonds)

          except IndexError:
            print ('Error: ', line)
csvfile.close()

print ("Read", len(diamondList), "diamond data")

我希望每个标准（例如钻石克拉）都将在列表中包含相关数据。
