Python Coding Challange - Question with Answer (01310825)

 

This tests the dictionary .get() method.

---

Code:

d = {"a":1, "b":2}
print(d.get("c", 99))

---

Step 1: Recall .get(key, default)

• dict.get(key, default) tries to fetch the value for key.

• If the key exists, it returns its value.

• If the key doesn’t exist, it returns the default value (or None if no default is given).

---

Step 2: Apply to this example

• Dictionary is:

  {"a":1, "b":2}

• Key "c" is not present.

• A default value 99 is provided.

So:

d.get("c", 99) → 99

---

Final Output:

99

---

✅ Explanation:
.get("c", 99) safely checks "c". Since "c" is missing, it returns the default 99 instead of raising a KeyError.
