如何在python中转换csv数据

Question

我有一个csv文件要转换。当前csv文件中的数据如下所示

115776 1142 1523 20197 20394 3421 1284 9572 19682 

但我希望它看起来像这样

^{pr2}$

。。。。。在

有什么办法吗？在

我现在写了一个函数来获取它，它是这样得到的

for row in read_csv(testfile, "Recipes_RecipeId Recipes_Ingredients_0_IngredientID Recipes_Ingredients_1_IngredientID Recipes_Ingredients_2_IngredientID Recipes_Ingredients_3_IngredientID Recipes_Ingredients_4_IngredientID Recipes_Ingredients_5_IngredientID Recipes_Ingredients_6_IngredientID Recipes_Ingredients_7_IngredientID Recipes_Ingredients_8_IngredientID".split()):
    with open('recipeIngredientID.csv', 'a') as csvfile:
        spamwriter = csv.writer(csvfile, delimiter=' ',
                            quotechar='|', quoting=csv.QUOTE_MINIMAL)
        spamwriter.writerow(row)

有没有更好的方法把它打印出来我想要它？在

Answer 1

将csv读入python列表：Python import csv to list

然后简单地循环列表，重复第一个索引：

test = [115776, 1142, 1523, 20197, 20394, 3421, 1284, 9572, 19682]

for i in test[1:]:
     print test[0], i
