Traversing a Tuple:

                      Syntax:   for <variable> in tuple-name:

                                                  Statement

Method-1

Method-2

jai=('q','w','e','r','t','y')

for i in jai:

       print(i)

Output:   q w e r t y

jai=('q','w','e','r','t','y')

for i in range(0, len(jai)):

         print(jai[i])

Output:   q w e r t y

Q.: Find the length of a tuple.

tup = (1, 2, 3, 4, 5)

length = len(tup)

print(length)

Q: Find the length of a tuple without len function.

jai = (1, 2, 3, 4, 5)

c=0

for i in jai:

    c=c+1

print(c)

Q: print the even no in a tuple.

jai = (1, 2, 3, 4, 5)

c=0

for i in jai:

    if(i%2==0):

        print(i)

Q: Write a program to print the sum of all tuple elements.

jai = (1, 2, 3, 4, 5)

sum=0

for i in jai:

    sum=sum+i

print(sum)
       

Tuple Operations:

  • Joining operator +
  • Repetition operator *
  • Slice operator [ : ]
  • Comparison Operator <, <=, >, >=, ==, !=

Joining Operator: It joins two or more tuples we can use + Operator

>>> T1 = (25,50,75)

>>> T2 = (5,10,15)

>>> T1+T2

                         Output:  (25, 50, 75, 5, 10, 15)

tuple1 = ("a", "b" , "c")

tuple2 = (1, 2, 3)

tuple3 = tuple1 + tuple2

print(tuple3)

  >>> T1 + (34)  # TypeError: can only concatenate tuple (not "int") to tuple

               >>> T1 + (34, )       Output: (25, 50, 75, 34)

Repetition Operator: It replicates a tuple, specified number of times. Or If you want to multiply the content of a tuple a given number of times, you can use the * operator:

Example:

>>> T1*2

(25, 50, 75, 25, 50, 75)

>>> T2=(10,20,30,40)

>>> T2[2:4]*3

(30, 40, 30, 40, 30, 40)
