如何使用Pandas作为字符串从.CSV文件直接读取度分秒（DMS）数据到数据帧中？

Question

如何使用熊猫作为字符串从.CSV文件直接读取度分秒（DMS）数据到数据帧中？ 例如： 如果我有一个csv文件，其中有一列DMS格式的数据，那么如何将其作为字符串读取到dataframe以进行进一步计算

76° 17' 51.2399" E
77° 26' 30.8322" E
76° 51' 29.7812" E
75° 45' 41.3540" E
76° 17' 51.2399" E

输入文件示例：enter link description here

当我使用pandas.read_csv（'test.csv）#test.csv是输入文件 我犯了一个错误

Traceback (most recent call last):

Answer 1

尝试使用不同的编码：

import pandas as pd
df = pd.read_csv('test1.csv', encoding='windows-1252')

Answer 2

CSV文件：

id,string
1,76° 17' 51.2399" E
2,77° 26' 30.8322" E
3,76° 51' 29.7812" E
4,75° 45' 41.3540" E
5,76° 17' 51.2399" E

代码：

df = pd.read_csv('test.csv')
print(df)

   id              string
0   1  76° 17' 51.2399" E
1   2  77° 26' 30.8322" E
2   3  76° 51' 29.7812" E
3   4  75° 45' 41.3540" E
4   5  76° 17' 51.2399" E
