Python Coding Challange - Question with Answer (01050825)

 

Let's break down this code line by line:

a = [5, 6, 7]

• A list a is created with three elements: [5, 6, 7].

---

b = a[:]

• This creates a shallow copy of list a and assigns it to b.

• The [:] slicing notation means: copy all elements of a.

• Now, a and b are two separate lists with the same values:

  a = [5, 6, 7] 
  b = [5, 6, 7]

---

b.remove(6)

• This removes the value 6 from list b.

• Now b = [5, 7], but a is still [5, 6, 7] because it was not changed.

---

print(a)

• This prints the original list a, which is still:

[5, 6, 7]

---

🔍 Summary:

• a[:] creates a new independent copy.

• Modifying b does not affect a.

• Output:

[5, 6, 7]
