Python Question / Quiz; What is the output of the following Python code, and why? Comment your answers below!
Answer: A) ['a', 'b', 'c'] x += 'c' works like x.extend('c')! › += iterates through the string 'c' › Since 'c' has one character, adds 'c' to list › Result: ['a', 'b', 'c'] For beginners: Try x += 'abc' and you'd get ['a','b','a','b','c'] each char added!
Answer: A — ['a', 'b', 'c'] ✅ += on a list acts like extend(), not append(). Strings are iterables, so 'c' is unpacked — one character at a time. x = ['a','b'] x += 'c' # extend # ['a','b','c'] Swap it for append('c') and the logic flips — append() adds the object, +=…
Answer: A) ['a', 'b', 'c'] Explanation: In Python, using += on a list extends it, not appends. Since 'c' is a string (which is iterable), Python adds its character 'c' to the list, not as a whole string, but as an element. So the output is ['a', 'b', 'c']
Answer is ['a', 'b', 'c']. To break down the given code: x = ['a', 'b'] # Initializing a list x with two elements: 'a' and 'b' x += 'c' # Using the += operator to add 'c' to the list x print(x) # Printing the updated list x For More Reference =>>
![KumarT00623760's tweet image. Answer is ['a', 'b', 'c'].
To break down the given code:
x = ['a', 'b'] # Initializing a list x with two elements: 'a' and 'b'
x += 'c' # Using the += operator to add 'c' to the list x
print(x) # Printing the updated list x

It's definitely not B. The correct choice is not listed in the other three. How do A, C, D differ from each other?
