Optimizations: Removed unnecessary initialization of mid before the loop. Avoid redundant comments that describe well-known binary search logic. Eliminated extra arithmetic operation in mid = low + (high - low) // 2 since (low + high) // 2 is sufficient in Python (no integer overflow issues like in C++). Direct comparison of nums[mid] == target before handling left/right half updates.
