CSV file:

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

Code:

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

Can you share a sample of your CSV file?

Try using different encoding:

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