Python Coding Challenge - Question with Answer (ID 180826)

Explanation:

Code

print(True << 3 | False)

Heading: Step 1 — True as an Integer

In Python, Boolean values behave like integers in arithmetic and bitwise operations:

True = 1

False = 0

So the expression becomes:

1 << 3 | 0

Heading: Step 2 — Left Shift <<

1 << 3

The << operator shifts the binary bits 3 positions to the left.

Binary representation:

1  →  0001

After shifting 3 positions:

0001 << 3

1000

Binary 1000 is decimal 8.

Therefore:

1 << 3

gives:

8

Heading: Step 3 — Bitwise OR |

Now we have:

8 | 0

Binary:

8 → 1000

0 → 0000

Bitwise OR gives 1 whenever at least one corresponding bit is 1:

1000

0000

----

1000

1000 in binary is 8.

Heading: Step 4 — Final Output

Therefore:

print(True << 3 | False)

produces:

8

Final Answer

Output: 8
