我正在尝试从一个目录读取多个csv文件。文件以摘要开头，而不是实际原始数据。原始数据从找到“ max”一词的地方开始，并且可以在任何行中。我有下面的代码，但它给我以下错误：IndexError：列表索引超出范围 谁能帮我解决这个问题？
csv_reader = csv.reader(open(file_path, 'rU'),dialect=csv.excel_tab)
max_found = False
max_row = None
for index, row in enumerate(csv_reader):
if row[index]=='max’:
print(row)
max_row = index
max_found = True
print(max_found)
df = pd.read_csv(file_path)
我尝试了以下修改的代码，但是程序不会停止运行。我可能做错了事。
n = 0
with open(file_path,'rU') as fp:
csv_reader = csv.reader(fp)
while True:
for line in csv_reader:
if line == "max":
break
print(line)
n = n + 1
df = pd.read_csv(file_path, skiprows=n)
答案 0 :(得分：0)

来读取数据，因此建议您这样做：
pd.read_csv()上面将在要读取的CSV中包含带有“ max”的行，如果您是指CSV以“ max”的行下方的行开始，请将n = 0
with open(file_path) as fp:
while True:
line = fp.readline()
if line.startswith("max"):
break
n = n + 1
df = pd.read_csv(file_path, skiprows=n)
行放在if语句之前。另外，在这里我假设文件中必须存在以“ max”开头的行。
