Python Coding Challange - Question With Answer(01230125)

 

Explanation

1. Input Lists:

   • a is a list of integers: [1, 2, 3]
   • b is a list of strings: ['x', 'y', 'z']

2. zip Function:

   • zip(a, b) combines elements from a and b into pairs (tuples). Each pair consists of one element from a and the corresponding element from b.
   • The result of zip(a, b) is an iterator of tuples: [(1, 'x'), (2, 'y'), (3, 'z')].

3. Convert to List:

   • list(zip(a, b)) converts the iterator into a list and assigns it to c.
   • c = [(1, 'x'), (2, 'y'), (3, 'z')].

4. Unpacking with zip(*c):

   • The * operator unpacks the list of tuples in c.
   • zip(*c) essentially transposes the list of tuples:
     • The first tuple contains all the first elements of the pairs: (1, 2, 3).
     • The second tuple contains all the second elements of the pairs: ('x', 'y', 'z').
   • Result: d = (1, 2, 3) and e = ('x', 'y', 'z').

5. Printing the Output:

   • print(d, e) prints the values of d and e:

     (1, 2, 3) ('x', 'y', 'z')

Key Concepts

• zip Function: Used to combine two or more iterables into tuples, pairing corresponding elements.
• Unpacking with *: Transposes or separates the elements of a list of tuples.

Output

(1, 2, 3) ('x', 'y', 'z')
