What is the dtype in the return data from loc?-CodePudding

df = pd.DataFrame([[2, 3], [5, 6], [8, 9]],
     index=['cobra', 'viper', 'sidewinder'],
     columns=['max_speed', 'shield'])
df.loc['viper']

Produces this output

max_speed    5
shield       6
Name: viper, dtype: int64

dtype is 'Data Type', but what does it refer to? The index label, viper, isn't int64.

CodePudding user response：

loc is to access the row and column by its name, the dtype here refer to the dtype of the resulting pd.Series object

Name : series name 

dtype : series data type

df.loc['viper']
max_speed    5
shield       6
Name: viper, dtype: int64
