How do you compare two sets?

Two sets A and B are equal if they have exactly the same elements. We write A = B. Two sets A and B are equivalent if n(A)= n(B). Another way of saying this is that two sets are equivalent if they have the same number of elements.

The IF Condition formula states if there is a match in the row when comparing two lists of data. If there is a match, the result of the formula will be “Matching” and if not then “Not Matching”. The formula would look something like this: =IF(A2=B2, “Matching”, “Not Matching”).

Can you compare two lists with == in Python?
