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)
