Python Coding Challenge - Question with Answer (ID 040826)

 

Explanation:

🔹 Line 1: Call print()

print("0" * False)

Before print() displays anything, Python first evaluates the expression:

"0" * False

🔹 Step 1: Understand the String

"0"

This is a string containing a single character.

Current Value:

"0"

Length:

1

🔹 Step 2: Evaluate False

False

Here's the trick.

In Python, bool is a subclass of int.

So internally:

False == 0

returns

True

This means Python treats:

False

as

0

So the expression becomes:

"0" * 0

🔹 Step 3: Multiply the String

Python now evaluates:

"0" * 0

String multiplication means:

Repeat the string N times.

Examples:

"A" * 3

Output

AAA

But here,

"0" * 0

means:

Repeat the string zero times.

So Python creates an empty string.

Result:

""

🔹 Step 4: Execute print()

Now Python executes:

print("")

Since the string is empty, nothing visible is printed.

The output appears as:

''

Final output:

""
