Hi@akhtar,

You can use astype function to change data types in Pandas. You can go through the below-given example.

data = {'col1': [1, 2], 'col2': [3, 4]}
df = pd.DataFrame(data=data)
df.dtypes
col1    int64
col2    int64
dtype: object

df.astype('int32').dtypes
col1    int32
col2    int32
dtype: object

I hope this will help you.
