) Data type conversions A solid arrow in the diagram indicates a loss-free conversion, and a dashed arrow indicates a conversion that may have a loss of precision. (e.g. 123 456 789 (int) is a large integer that contains more bits than can be expressed by the float type (a valid number 6~7 bit), and when this integer value is converted to float, the result is the same size, But the loss of a certain degree of accuracy (after the number of decimals can not be ac

difference is that the list can be changed, and tuples cannot be changed.4-9 Exercise, given the following assignment:A = tenB = TenC =d =e = 10.0f = 10.0what is the output of the following expressions?Why? In Python, integer and string objects are non-mutable objects, and Python caches them very efficiently, causing us to think that Python should create new objects without the illusion of creating new objects. Therefore, returns True when the first two integers are compared, and returns false
