Tuple Methods

Let's dive into the primary methods associated with tuples.

len(t) - gives the number of elements in the tuple t;
t * n - produces n repetitions of the tuple t;
t.count(x) - counts how often x appears in the tuple t.

In the previous chapter, we highlighted that tuples are immutable. So, you might wonder: "How can I update a tuple with new values?"

Unlike lists, you can't use methods like .append() or .extend() with tuples. However, remember a few chapters back when we discussed concatenation? Here's the method that works for tuples too:

tuple1 + tuple2 - this joins two tuples together (both elements must be tuples).

For instance, let's add some new data to the tuple we were working with in the last example.

Just a heads up: make sure the data you're adding is also in tuple format to successfully concatenate.


              1234567
            
# Initial tuple
US_Info = ("USA", 9629091, 331002651)
# New data
US_Info_new = ("Washington D.C.", 50)
# Concatenate two tuples and save the result
US_Info_upd = US_Info + US_Info_new
print(US_Info_upd)

Everything was clear?
