Question

what will be printed if we run the following code. (replace newline characters with a space in the answer.)
a a b c d
b e f g
c a b c d e f g
d e
e f
f g
letters = \a\, \b\, \c\, \d\
letters.append(\e\)
letters.append(\f\)
letters.append(\g\)
for letter in letters:
print(letter)

Explanation:

Step1: Analyze the list initialization

The list letters is initialized as ["a", "b", "c", "d"].

Step2: Analyze the append operations

Three append operations add "e", "f", "g" to the list. So the list becomes ["a", "b", "c", "d", "e", "f", "g"].

Step3: Analyze the loop

The for loop iterates over each element in the letters list and prints each element.

Answer:

a b c d e f g
