Python: Create an iterator from several iterators

Python Itertools: Exercise-1 with Solution

Write a Python program to create an iterator from several iterables in a sequence and display the type and elements of the new iterator.

Sample Solution:

Python Code:

from itertools import chain
def chain_func(l1,l2,l3):
    return chain(l1,l2,l3)    
#List
result = chain_func([1,2,3], ['a','b','c','d'], [4,5,6,7,8,9])
print("Type of the new iterator:")
print(type(result))
print("Elements of the new iterator:")
for i in result:
    print(i)

#Tuple
result = chain_func((10,20,30,40), ('A','B','C','D'), (40,50,60,70,80,90))
print("Type of the new iterator:")
print(type(result))
print("Elements of the new iterator:")
for i in result:
    print(i)

Sample Output:

Type of the new iterator:
<class 'itertools.chain'>
Elements of the new iterator:
1
2
3
a
b
c
d
4
5
6
7
8
9
Type of the new iterator:
<class 'itertools.chain'>
Elements of the new iterator:
10
20
30
40
A
B
C
D
40
50
60
70
80
90
