Tuple () function in Python

In Python, tuple is an immutable sequence. The built-in function tuple () in Python is used to create a tuple.

The syntax of the tuple () function in Python

 tuple(iterable)

Parameter of tuple function ()

The tuple () function in Python has parameters:

  1. iterable : iterable objects are built-in (like list, string, dict) or iterator object.

Value returned from tuple ()

  1. If no parameters are passed, tuple () returns an empty tuple.
  2. If the iterable parameter is passed, tuple () returns the corresponding tuple.

Example: How to create tuple with tuple ()?

 t1 = tuple() 
 print('t1=', t1) 
 
 # tạo một tuple từ list 
 t2 = tuple([2, 4, 6, 8, 10, 12, 14, 16, 18, 20]) 
 print('t2=', t2) 
 
 # tạo một tuple từ string 
 t1 = tuple('Quantrimang') 
 print('t1=',t1) 
 
 # tạo một tuple từ dictionary 
 t1 = tuple({1: 'one', 2: 'two'}) 
 print('t1=',t1)

Run the program, the result is:

 t1= () 
 t2= (2, 4, 6, 8, 10, 12, 14, 16, 18, 20) 
 t1= ('Q', 'u', 'a', 'n', 't', 'r', 'i', 'm', 'a', 'n', 'g') 
 t1= (1, 2)
