Programming in Python Theory

PYTHON NUMBERS Number data types store numeric values. They are immutable data types, which means that changing the value of a number data type results in a newly allocated object. Number objects are created when you assign a value to them. For example You can also delete the reference to a number object by using the del statement. The syntax of the del statement is − You can delete a single object or multiple objects by using the del statement. For example − There are three numeric types in Python: int float complex Variables of numeric types are created when you assign a value to them: To verify the type of any object in Python, use the type() function: Example : NUMBER TYPE CONVERSION Python converts numbers internally in an expression containing mixed types to a common type for evaluation. But sometimes, you need to coerce a number explicitly from one type to another to satisfy the requirements of an operator or function parameter. Type int(x) to convert x to a plain integer. Type...
