Pt-duplicate-key-checker is also a very useful tool in Percona-toolkit to help you detect duplicate indexes or primary keys in a table. We know that indexes can be more useful than queries, but too much indexing can degrade the performance of the database, and this tool can help us find duplicate indexes and give you suggestions for deleting duplicate indexes.
First look at the index structure of my table

A simple method to implement the type checker in Python 3, python type
Example Function
To develop a type checker, we need a simple function to experiment with it. The euclidean algorithm is a perfect example:
def gcd(a, b): '''Return the greatest common divisor of a and b.''' a = abs(a) b = abs(b) if a
In the preceding example, parameters a, B, and return values are of the int type. The expected types
