IndentationError:应为缩进块dataset=list（）

Question

运行下面的第二个代码时出现此错误。有人能告诉我如何修复它吗？你知道吗

File "<ipython-input-2-b17fa66ce8c6>", line 3
    dataset = list()
          ^
IndentationError: expected an indented block


def load_csv(filename):
dataset = list()
with open(filename, 'r') as file:
csv_reader = reader(file)
for row in csv_reader:
if not row:
continue
dataset.append(row)
return dataset

Answer 1

制表符和空格在Python中非常重要。您的代码应该如下所示：

def load_csv(filename):
    dataset = list()
    with open(filename, 'r') as file:
        csv_reader = reader(file)
        for row in csv_reader:
            if not row:
                continue
            dataset.append(row)
    return dataset
