Logical errors need to be found and corrected by people working on the program. Data Types Data Type specifies which type of value a variable can store. An implicit type conversion is automatically performed by the compiler when differing data types are intermixed in an expression. Value can be found using the built-in function print() like this:print(a). In the line print (type (int("Hello"))), string "Hello" is given as an argument to int() but it cannot be converted into a valid integer so it causes an error.
