How does the del operator work on a tuple in Python?

PythonServer Side ProgrammingProgramming

Removing individual tuple elements is not possible. There is, of course, nothing wrong with putting together another tuple with the undesired elements discarded using list comprehensions or slicing. To explicitly remove an entire tuple, you can use the del statement. 

example

tup = ('physics', 'chemistry', 1997, 2000)
print(tup)
del(tup)
print("After deleting tup : ")
print(tup)

This will give the following output. Note an exception raised, this is because after del tup tuple does not exist any more.

Example

('physics', 'chemistry', 1997, 2000)
After deleting tup :
Traceback (most recent call last):
   File "test.py", line 9, in <module>
      print tup;
NameError: name 'tup' is not defined
