If the dictionary D1 is defined as: D1 = {1: ‘a’, 2: ‘b’} then which of the…

To determine which statement will result in an error, we analyze each option based on Python dictionary methods.

Option A: D1.get(1)

The get() method retrieves the value for a given key. Since key 1 exists in D1, it returns 'a'. This operation is valid and does not raise an error.

Option B: D1.get(3)

The get() method returns None if the key is not found. Key 3 is not in D1, so it returns None. This operation is valid and does not raise an error.

Option C: D1.del(1)

The dictionary does not have a del() method. The correct way to delete a key is using 'del D1[1]' or 'D1.pop(1)'. Using D1.del(1) raises an AttributeError.

Option D: D1.clear(1)

The clear() method removes all items from the dictionary but does not accept any arguments. Passing an argument like 1 raises a TypeError.

Thus, both Option C and Option D will result in errors. However, the question asks for the incorrect statement that will result in an error. The key is to identify which one is syntactically invalid.

हिन्दी उत्तर:

D1.get(1) और D1.get(3) दोनों वैध हैं क्योंकि get() विधि अस्तित्वहीन कुंजी के लिए None लौटाती है और त्रुटि नहीं उठाती। D1.del(1) गलत है क्योंकि डिक्शनरी में del() विधि नहीं होती है। D1.clear(1) भी गलत है क्योंकि clear() कोई आर्गुमेंट नहीं लेती है। दोनों त्रुटियाँ उठाती हैं, लेकिन D1.del(1) एक विधि नहीं होने के कारण त्रुटि उठाती है।
