Python – Clearing a tuple
Sometimes, while working with Records data, we can have a problem in which we may require to perform clearing of data records. Tuples, being immutable cannot be modified and hence makes this job tough. Let’s discuss certain ways in which this task can be performed.
Method #1 : Using list() + clear() + tuple()
The combination of above 3 finctions can be used to perform this task. In this, we interconvert the tuple to list, clear it and again convert to tuple using tuple().
# Python3 code to demonstrate # Clearing a tuple # using list() + tuple() + clear() # initializing tuple test_tup = (1, 5, 3, 6, 8) # printing original tuple print("The original tuple : " + str(test_tup)) # Clearing a tuple # using list() + tuple() + clear() temp = list(test_tup) temp.clear() test_tup = tuple(temp) # print result print("The tuple after clearing values : " + str(test_tup)) |

Output :
The original tuple : (1, 5, 3, 6, 8) The tuple after clearing values : ()
Method #2 : Reinitialization using tuple()
Another straight forward way to perform this task is to reinitialize tuple using tuple() which will return empty tuple.
# Python3 code to demonstrate # Clearing a tuple # using Reinitialization + tuple() # initializing tuple test_tup = (1, 5, 3, 6, 8) # printing original tuple print("The original tuple : " + str(test_tup)) # Clearing a tuple # using Reinitialization + tuple() test_tup = tuple() # print result print("The tuple after clearing values : " + str(test_tup)) |

Output :
The original tuple : (1, 5, 3, 6, 8) The tuple after clearing values : ()
