• 0 1 2 0
• 0 1 2
• Throws an error
• None of the above

• [1, 2, 3]
• ['One', 'Two', 'Three']
• [2, 3]
• ['Two', 'Three']

Output:

Explanation:
$V$ (a string) is the value of dictionary in each iteration. V[0] means the first character of the string, so if the first character of a value is equal to 'T', the empty list $L$ will be appended by the corresponding key to the value of dictionary $D$.

Q38. What will be the Output of the Following Python Code? (For Loop, String)

• None
• Nothing is printed

• [2.1, 2, '4']
• [2.1, 3, '4']
• [2.1, 3]
• Throws an error
