Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric python packages. Pandas is one of those packages and makes importing and analyzing data much easier.
Index.difference() function return a new Index with elements from the index that are not in other.
The function automatically sorts the output if sorting is possible.
other : Index or array-like
Returns : difference : Index
Example #1: Use
Index.difference() function to find the set difference of a given Index with an array-like object.
Let’s find the set difference of the given Index with an array-like object
As we can see in the output, the function has returned an object which contains only those values which are unique to the idx Index.
Note that the output object has its element sorted in Increasing order.
Example #2: Use
Index.difference() function to find the set difference of two Indexes.
Now, let’s find the set difference between two Indexes.
The function has returned the set difference of idx1 and idx2. It contains only those values which are unique to idx1 Index. Note that the output is not sorted.
