Python Coding Challenge - Question with Answer (ID 280926)

 

Explanation:

🟢 1. Store "10" in x

x = "10"

Here, "10" is a string, not an integer.

x → "10"

🟡 2. x * 2

x * 2

Since x is a string, * 2 repeats the string.

"10" * 2

becomes:

"1010"

⚠️ It does not mean 10 × 2.

🔵 3. int(x)

int(x)

The string "10" is converted into the integer 10.

"10" → 10

🟠 4. int(x) // 2

Now Python performs floor division:

10 // 2

Result:

5

🟣 5. str(int(x) // 2)

The result 5 is converted back into a string:

str(5)

Result:

"5"

🔴 6. String Concatenation

Now the expression becomes:

"1010" + "5"

Because both values are strings, + joins them:

"10105"

⚡ Complete Flow

x = "10"

   ↓

x * 2

   ↓

"1010"

int(x) // 2

   ↓

10 // 2

   ↓

5

   ↓

str(5)

   ↓

"5"

"1010" + "5"

   ↓

"10105"

✅ Final Output

10105
