In many coding languages, when you try to combine a string with a number, the number is usually converted into a string automatically so both parts can be joined together. This is called implicit type conversion. With the + operator for contaminating a string with a numerical value, Python does ... Read More

Usually, if we need to find a particular word such as, "data" in a text or a string we will directly search for it. We can also use a sequence of characters which forms a pattern to search for words in a string. For example the characters "[0-9]" matches a ... Read More

In Python, especially in situations like iterating through data structures, working with built-in functions, or fetching records from a database, lists of tuples are returned by the pre-defined functions instead of a list of lists. This is because tuples are immutable i.e., we cannot modify them after creation, whereas lists are mutable; ... Read More
