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.

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.
