Typing refers to the data types of variables in a programming language. Dynamic typing refers tothat in python the variable's data type is assigned based on its value, and not be declared explicitly unlike c or cpp or other such Typed Languages. For example, x=10 y='Hello World' z=10.5 Here python declares x as 'int' y as 'str' and z as 'float' data types. This also means, a variable can be dynamically typed during run time of the program. For an example, while writing the program, if later you introduce a statement like this; y=200.75 then, y becomes float. Hence, Python is a dynamic typed language and the type of variable is implicitly declared based upon its value. This has pros and cons as well. For an example, if a int type of variable is accidentaly or unexpectedly changed to a string type during run time, then the calculations based on that error might raise an exception. read less

Java- static language- you need to declare variable type (int, float, str,etc) at initial. and we can not change variable type later in program. python - Dynamically type langauge - no need to declare variable type. we can assign any value to variable as we write the program further.

Can anyone help me with the below programs: A) which returns orger summary as a list with 2- tuples. Each tuple consists of the order number and the product of the price per items and the quantity. OUTPUT: [ ('34587',163.8),('98762',284.0),('77226',98.85),('88112',74.97) ]. 10 INR should be increased in the product if the value of the order is smaller than 100.00 INR. OUTPUT: [ ('34587',163.8),('98762',284.0),(77226',108.85),('88112',84.97) ]
Can't solve because product price is a part of the tuple. Since LIST IS MUTABLE so we can change its elements. We can change the whole tuple because it is an element of the list. As WKT TUPLE IS IMMUTABLE so we can't change its elements.
