Statically typed programming languages do type checking (the process of verifying and enforcing the constraints of types) at compile-time as opposed to run-time. Dynamically typed programming languages do type checking at run-time as opposed to Compile-time.
Python
is a strong, dynamically typed . As the interpreter keeps track of all variables types.
This feature makes python syntax wise very easy. There is no need to declare data type with variable declaration time.
For example ,
In C , C++
int a=78;
float b=90.876;
If we forget to write data type then it will be compile time Error.
But in Python just simple declare
a=10;
b=90.876;
Whatever value assigned to the variable that related type is assigned at run time.
