modin.pandas.DataFrame.T¶
- property DataFrame.T: DataFrame[source] (https://github.com/snowflakedb/snowpark-python/blob/v1.26.0/snowpark-python/.tox/docs/lib/python3.9/site-packages/modin/pandas/dataframe.py#L614-L622)¶
Transpose index and columns.
Reflect the DataFrame over its main diagonal by writing rows as columns and vice-versa. The property T is an accessor to the method transpose().
- Parameters:
tuple (*args) – Accepted for compatibility with NumPy. Note these arguments are ignored in the snowpark pandas implementation unless go through a fallback path, in which case they may be used by the native pandas implementation.
optional – Accepted for compatibility with NumPy. Note these arguments are ignored in the snowpark pandas implementation unless go through a fallback path, in which case they may be used by the native pandas implementation.
bool (copy) – Whether to copy the data after transposing, even for DataFrames with a single dtype. The snowpark pandas implementation ignores this parameter.
False (default) – Whether to copy the data after transposing, even for DataFrames with a single dtype. The snowpark pandas implementation ignores this parameter.
DataFrames (Note that a copy is always required for mixed dtype) –
types. (or for DataFrames with any extension) –
- Returns:
- DataFrame
The transposed DataFrame.
- Examples::
Square DataFrame with homogeneous dtype
>>> d1 = {'col1': [1, 2], 'col2': [3, 4]} >>> df1 = pd.DataFrame(data=d1) >>> df1 col1 col2 0 1 3 1 2 4
>>> df1_transposed = df1.T # or df1.transpose() >>> df1_transposed 0 1 col1 1 2 col2 3 4
When the dtype is homogeneous in the original DataFrame, we get a transposed DataFrame with the same dtype:
>>> df1.dtypes col1 int64 col2 int64 dtype: object
>>> df1_transposed.dtypes 0 int64 1 int64 dtype: object
Non-square DataFrame with mixed dtypes
>>> d2 = {'name': ['Alice', 'Bob'], ... 'score': [9.5, 8], ... 'employed': [False, True], ... 'kids': [0, 0]} >>> df2 = pd.DataFrame(data=d2) >>> df2 name score employed kids 0 Alice 9.5 False 0 1 Bob 8.0 True 0
>>> df2_transposed = df2.T # or df2.transpose() >>> df2_transposed 0 1 name Alice Bob score 9.5 8.0 employed False True kids 0 0
When the DataFrame has mixed dtypes, we get a transposed DataFrame with the object dtype:
>>> df2.dtypes name object score float64 employed bool kids int64 dtype: object
>>> df2_transposed.dtypes 0 object 1 object dtype: object
