Concept: Tuple methods & operators

A tuple can be used with all methods for lists, except for those that modify the contents of a list.

• len(): Returns the number of items in the tuple.

  ftp_socket = ('ftp', '192.168.1.65', '21')
  print(len(ftp_socket)) # Output: 3

• join(): Joins the elements of a tuple into a string, using a specified separator.

  ftp_socket = ('ftp', '192.168.1.65', '21')
  print(' '.join(ftp_socket)) # Output: ftp 192.168.1.65 21

• count(): Returns the number of occurrences of a specified item in the tuple.

  users = ('Alice', 'Bob', 'Eve', 'Alice')
  print(users.count('Alice')) # Output: 2

All operators that work with lists also work with tuples.

Operator	Description	Example	Result
+	Concatenation	('a', 'b') + ('c', 'd')	('a', 'b', 'c', 'd')
*	Repetition	('a', 'b') * 2	('a', 'b', 'a', 'b')
<	Less than	('a', 'b') < ('c', 'd')	True
>	Greater than	('a', 'b') > ('c', 'd')	False
==	Equal to	('a', 'b') == ('a', 'b')	True
!=	Not equal to	('a', 'b') != ('c', 'd')	True
in	Membership	'a' in ('a', 'b')	True
not in	Not membership	'c' not in ('a', 'b')	True
