28. Difference between == and “is”
“is” checks whether 2 variables are pointing to the same object in memory.“==” compares the equality of values that these 2 objects hold.
29. Check whether a string starts with a particular character without using the index 0
30. Find the unique id of a variable using id()
31. Integers, floats, strings, booleans, and tuples are immutable
When we assign a variable to an immutable type such as integers, floats, strings, booleans, and tuples, then this variable points to an object in memory.In case we assign another to that variable another value, the original object is still in memory, but the variable pointing to it is lost.
32. Strings and tuples are immutable
33. Lists, sets, and dictionaries are mutable
This means that we can change the object without losing binding to it.
