Python Coding Challenge - Question with Answer (ID -100626)

 

Explanation:

1. Dictionary Creation

{"python": 3.14}

This creates a dictionary with:

Key: "python"

Value: 3.14

The dictionary looks like:

{

    "python": 3.14

}

2. Calling the get() Method

{"python": 3.14}.get("java", 0)

The get() method is used to retrieve a value from a dictionary.

Syntax:

dictionary.get(key, default_value)

Here:

key = "java"

default_value = 0

So Python searches for the key "java" in the dictionary.

3. Key Lookup

Python checks:

{

    "python": 3.14

}

Does the key "java" exist?

Answer: No.

Available key:

"python"

Requested key:

"java"

Since "java" is not found, get() does not raise an error.

4. Returning the Default Value

Because the key is missing, get() returns the provided default value:

0

So:

{"python": 3.14}.get("java", 0)

evaluates to:

0

5. print() Function

Now Python executes:

print(0)

The print() function displays the value on the screen.

Output

0
