Trying to convert kaggle titanic dataset pclass column datatype from int to string. Using pandas 1.0.5.

df.Pclass.head()
0    3
1    1
2    3
3    1
4    3
Name: Pclass, dtype: int64

Code is below:

df['Pclass'] = df['Pclass'].astype('string')

Thrown error as below:

The below code worked. As pandas >= 1.0, they have suggested to use string instead of str. But if source is numeric then we can use str instead of string to work.

df['Pclass'] = df['Pclass'].astype('str')
