Typing refers to the data types of variables in a programming language. Dynamic typing refers to that 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.
