Python Programs on Tuples

Python Programs on Tuples:

1. Write a Python program to test if a variable is a list or tuple or a set.

Ans.

#x = ['a', 'b', 'c', 'd']
#x = {'a', 'b', 'c', 'd'}
x = ('tuple', False, 3.2, 1)
if type(x) is list:
    print('x is a list')
elif type(x) is set:
    print('x is a set')
elif type(x) is tuple:
    print('x is a tuple')   
else:
    print('Neither a list or a set or a tuple.')

2. Write a Python program to sort a list of tuples by the second Item.

Ans.

def Sort_Tuple(tup):
    lst = len(tup)
    for i in range(0, lst):
        for j in range(0, lst-i-1):
            if (tup[j][1] > tup[j + 1][1]):
                temp = tup[j]
                tup[j]= tup[j + 1]
                tup[j + 1]= temp
    return tup
 
tup =[('for', 2), ('is', 9), ('to', 7),('Go', 5), ('or', 15), ('a', 13)]
print(Sort_Tuple(tup)) 

3. Write a Python program which accepts a sequence of comma-separated numbers from user and generate a list and a tuple with those numbers.

Ans.

values = input("Input some comma seprated numbers : ")
list = values.split(",")
tuple = tuple(list)
print('List : ',list)
print('Tuple : ',tuple) 

4. Write a python program to print sum of tuple elements.

Ans.

test_tup = (7, 5, 9, 1, 10, 3) 
print("The original tuple is : " + str(test_tup)) 
 
res = sum(list(test_tup))
 
# printing result 
print("The sum of all tuple elements are : " + str(res))

5. Write a Python program to sort a list of tuples alphabetically

Ans.

def SortTuple(tup):
    n = len(tup)
     
    for i in range(n):
        for j in range(n-i-1):
             
            if tup[j][0] > tup[j + 1][0]:
                tup[j], tup[j + 1] = tup[j + 1], tup[j]
    return tup
 
tup = [("Amaruta", 20), ("Zoe", 32), ("Akshay", 25),
        ("Nilesh", 21), ("C", "D"), ("Penny", 22)]
print(SortTuple(tup))

6. Write a python program to Check if the given element is present in tuple or not.

Ans.

test_tup = (10, 4, 5, 6, 8)
 
# printing original tuple
print("The original tuple : " + str(test_tup))
 
N = int(input("value to be checked:")) 
res = False
for ele in test_tup :
    if N == ele :
        res = True
        break
print("Does contain required value ? : " + str(res))
