We use the predefined functions like int(), float(), str(), etc to perform explicit type conversion. One thing to remember is that the key should be unique in nature; otherwise, the existing value will be replaced and overwritten. For example, br'\101'.decode('unicode-escape') yields the Unicode (string) character 'A'. In Type Casting, loss of data may occur as we enforce the object to a specific data type. In the above example, we have explicitly converted the string to an integer data type using an int() function. 1-What does "non-string - with explicit base" means? ord() In explicit type conversion, python uses inbuilt functions which convert a given data type to another required data type.
