What is the output of the following Python code?
The ans is A. [] [''] 👉 The key theme of the entire problem is understanding how the `split()` and `splitlines()` functions work with strings in Python, especially when the string contains only newline characters. Let me explain step by step for Beginners in Python --------------- 👉 The given code initializes a string `s` with just the newline character `\n`. ```python s = '\n' ``` 👉 The `split()` method in Python divides a string around each instance of a specified delimiter. If the delimiter is not specified (as in our case), it uses whitespace as the default delimiter. Whitespace includes spaces, tabs, and newline characters. 👉 In our scenario, when `split()` is applied to `s`: ```python s.split() ``` Since `s` contains only a newline character and no other content, the `split()` function sees it as a delimiter and does not include it in the result. Hence, an empty list is returned. --- 👉 Now, moving onto the `splitlines()` function. The purpose of `splitlines()` is to split a string at line breaks. It returns a list of lines in the string. 👉 When we call `splitlines()` on our string `s`: ```python s.splitlines() ``` It considers the newline as an indication of a new line. For our string, `s = '\n'`. When using `splitlines()`, Python notices the newline character and knows that it needs to split the string there. But since there's no content before or after the newline character in this particular string, it results in an empty string for the content that should be "before" the newline. 👉 The essence here is that `splitlines()` recognizes the newline as a separator and will represent the segments separated by the newline as individual strings in the resulting list. If there's nothing before or after the newline, the corresponding segment will be an empty string. --- 👉 So, when we look at the combined output of both methods: ```python print(s.split(), s.splitlines()) ``` The result is an empty list from `split()` and a list with an empty string from `splitlines()`. This gives us the observed output: ``` [] [''] ``` 👉 In essence, this exercise highlights the nuanced differences between the behaviors of `split()` and `splitlines()`. While both can handle newline characters, the way they process and represent the result differs. ------------------ 👉 If you enjoyed this explanation: ✅1.

@clcoding The answer is A The output is a tuple which contains 2 lists S.split() : return a list of substrings using separator which don't exists here so it returns an empty list S.splitlines() : return a list of lines without including linebreaks I hope it makes sense to you
@clcoding The output is A no doubt s = '\n' print(s.split(), s.splitlines()) # Output: # [] # ['']
The correct answer is: D: [''] [] Explanation: - `s.split()` splits the string `s` by whitespace and returns an empty list because there are no spaces or other characters in `s`. - `s.splitlines()` splits the string `s` by newline characters (`\n`) and returns a list with an empty string `''` because `s` contains a newline character. So, the correct output is `[''] []`, which corresponds to option D.
