In Python Call by Value and Call by Reference are two types of generic methods to pass parameters to a function. In the Call-by-value method, the original value cannot be changed, whereas in Call-by-reference, the original value can bechanged. Call by Value in Python When we pass an argument to a function, it is stored locally (in the stack memory), i.e the scope of these variables lies with in the function and these will not have effect the values of the golbal variables (variables outside function). In Python, "passing by value" is possible only with the immutable types such as integers, floats, strings, ... Read More

While working with a database to avoid duplicates, we should follow certain practices when we create the database table. Define primary key to identify rows cluster and non-cluster indexes. Use constraints for data integrity in performance. Database tables may have duplicate rows after following best practices. These duplicate rows create issues while we retrieve data from the database. So we must ensure unique database rows. To do so, first of all, we need to verify whether a table has duplicate rows, If duplicate rows exist, we must remove them by altering the table data. This article will ... Read More
