pandas.Index.equals¶
- Index.equals(other)[source]¶
Determine if two Index object are equal.
The things that are being compared are:
The elements inside the Index object.
The order of the elements inside the Index object.
- Parameters:
- otherAny
The other object to compare against.
- Returns:
- bool
True if “other” is an Index and it has the same elements and order as the calling index; False otherwise.
Examples
>>> idx1 = pd.Index([1, 2, 3]) >>> idx1 Int64Index([1, 2, 3], dtype='int64') >>> idx1.equals(pd.Index([1, 2, 3])) True
The elements inside are compared
>>> idx2 = pd.Index(["1", "2", "3"]) >>> idx2 Index(['1', '2', '3'], dtype='object')
>>> idx1.equals(idx2) False
The order is compared
>>> ascending_idx = pd.Index([1, 2, 3]) >>> ascending_idx Int64Index([1, 2, 3], dtype='int64') >>> descending_idx = pd.Index([3, 2, 1]) >>> descending_idx Int64Index([3, 2, 1], dtype='int64') >>> ascending_idx.equals(descending_idx) False
The dtype is not compared
>>> int64_idx = pd.Index([1, 2, 3], dtype='int64') >>> int64_idx Int64Index([1, 2, 3], dtype='int64') >>> uint64_idx = pd.Index([1, 2, 3], dtype='uint64') >>> uint64_idx UInt64Index([1, 2, 3], dtype='uint64') >>> int64_idx.equals(uint64_idx) True
