1. Define empty tuple. Write syntax to create empty tuple.
An empty tuple in Python is a tuple that contains no elements.
Using Empty Parentheses
Simplest way to create an empty tuple is by using ( ).
# Creating an empty tuple using parentheses
t = ()
print(t)
print(type(t))
print(len(t))
Output
()
<class 'tuple'>
0
2. Write syntax to copy specific elements existing tuple into new tuple.
t1 = (10,20,30,40,50,60,70,80,90,100)
t2 = t1[2:8]
print(t2)
Output
(30, 40, 50, 60, 70, 80)

Exercise
1. Create a tuple and find the minimum and maximum number from it.
>>> tup = (22, 3, 45, 4, 2.4, 2, 56, 890, 1)
>>> max(tup)
890
>>> tup = (22, 3, 45, 4, 2.4, 2, 56, 890, 1)
>>> min(tup)
2. Write a Python program to find the repeated items of a tuple.
t = (2,34,45,6,7,2,4,5,78,34,2)
print(t)
count = t.count(2)
print(count)
Output
(2, 34, 45, 6, 7, 2, 4, 5, 78, 34, 2)
3. Print the number in words for Example: 1234 => One Two Three Four
num = int(input("Enter any number:"))
t = list()
while num > 0:
rem = num %10
if rem == 0:
t.append("Zero")
elif rem == 1:
t.append("One")
elif rem == 2:
t.append("Two")
elif rem == 3:
t.append("Three")
elif rem == 4:
t.append("Four")
elif rem == 5:
t.append("Five")
elif rem == 6:
t.append("Six")
elif rem == 7:
t.append("Seven")
elif rem == 8:
t.append("Eight")
elif rem == 9:
t.append("Nine")
num = num // 10
for i in range(len(t)-1,-1,-1):
print(t[i],end=" ")
Output
Enter any number:4568
Four Five Six Eight
