但是，

read\u csv

与

“{”type:“Polygon”，“coordinates:

中的

，

混淆。我希望它忽略引号中的

，

。

尝试以下操作：

import pandas as pd
df = pd.read_csv('file.csv')

您的csv文件包含多索引，这会导致读取和拆分问题

我尝试了多种方法来正确读取您的文件。到目前为止，我发现最好的方法是使用Python引擎，在read_csv函数中使用高级分隔符

pd.read_csv('file.csv',quotechar='"',skipinitialspace=True)

---

我认为这是由于您的csv文件格式错误造成的。单元格中的双引号（“”）应转义到此（“”）。此格式错误的csv的来源是什么？我的回答是否解决了您的问题？如果没有，请具体跟进，以便解决任何未解决的问题。谢谢

import pandas as pd

# these are for viewing the output
pd.set_option('display.max_columns', 30)

pd.set_option('display.width', 120)

# The separator matches the format of the string that you provided.
# I'm sure that it can be modified to be more efficient.
df = pd.read_csv('test.csv', skiprows=1, sep='(\d{1,2}.\d{1,8}),(\d{1,2}.\d{1,8}),("{"type":.*)',engine="python")

# read in the new file
