I’m currently working through technical interview challenges to improve my backend development skills, and I recently completed the Zigzag Conversion problem on LeetCode. This is my solution. class Solution: def convert(self, s: str, numRows: int) -> str: if numRows <= 1: return s rows = ['' for _ in range(numRows)] current_row = 0 going_down = False for char in s: rows[current_row] += char if current_row == 0 or current_row == numRows - 1: going_down = not going_down current_row += 1 if going_down else -1 return ''.join(rows) I'd love any advice or feedback from the community on: Improving readability and structure Would you use the 'walrus' operator from python 3.8 Writing more scalable or optimized logic Other cleaner or Pythonic approaches Any best practices you’d apply to make this code more professional Continue reading...
