Check whether the provided array or dtype is of an integer dtype.
Unlike in is_any_int_dtype, timedelta64 instances will return False.
The nullable Integer dtypes (e.g. pandas.Int64Dtype) are also considered as integer by this function.
The array or dtype to check.
Whether or not the array or dtype is of an integer dtype and not an instance of timedelta64.
Examples
>>> from pandas.api.types import is_integer_dtype
>>> is_integer_dtype(str)
False
>>> is_integer_dtype(int)
True
>>> is_integer_dtype(float)
False
>>> is_integer_dtype(np.uint64)
True
>>> is_integer_dtype('int8')
True
>>> is_integer_dtype('Int8')
True
>>> is_integer_dtype(pd.Int8Dtype)
True
>>> is_integer_dtype(np.datetime64)
False
>>> is_integer_dtype(np.timedelta64)
False
>>> is_integer_dtype(np.array(['a', 'b']))
False
>>> is_integer_dtype(pd.Series([1, 2]))
True
>>> is_integer_dtype(np.array([], dtype=np.timedelta64))
False
>>> is_integer_dtype(pd.Index([1, 2.])) # float
False
