我有一个 CSV，它有三个不同的分隔符，即“|”、“,”和“;”不同列之间。
我如何使用Python解析这个CSV？
我的数据如下：

坚持使用标准库，re.split()可以在以下任意字符处分割一行：
import re
with open(file_name) as fobj:
for line in fobj:
line_data = re.split('Delim_first|Delim_second|[|]', line)
print(line_data)
这将在分隔符处分割|, Delim_first, and Delim_second.
或者用熊猫：
import pandas as pd
df = pd.read_csv('multi_delim.csv', sep='Delim_first|Delim_second|[|]',
engine='python', header=None)
