Python maintains a symbol table to keep all necessary information about a program. What is Garbage Collection?Answer: The concept of removing unused or unreferenced objects from the memory location is known as a Garbage Collection.While executing the program, if garbage collection takes place then more memory space is available for the program and rest of the program execution becomes faster.The garbage collector is a predefined program, which removes the unused or unreferenced objects from the memory locationAny object reference count becomes zero then we call that object as an unused or unreferenced objectThen no.of reference variables which are pointing the object is known as a reference count of the object.While executing the python program if any object reference count becomes zero, then internally python interpreter calls the garbage collector and garbage collector will remove that object from memory location. 33.
