Qatordagi oxirgi nuqtadan keyingi barcha belgilarni olib tashlash uchun regex ifodasi yarating. Masalan, agar menda "X.Y.4" namunasi bo'lsa, men 4 raqami va nuqtani olib tashlashni xohlayman.<|eot_id|><|start_header_id|>assistant<|end_header_id|>

Stringdagi oxirgi nuqtadan keyingi barcha belgilarni olib tashlash uchun quyidagi oddiy ifodani ishlatishingiz mumkin: `/\.[^.]*$/` Ushbu oddiy ifodani stringning oxirida nuqta (`.`) va undan keyin nuqta bo'lmagan belgilar (`[^.]*`) bilan almashtiring. Ushbu oddiy ifodani kodingizda ishlatish uchun siz stringning mos bo'lgan qismini bo'sh stringa almashtirishingiz mumkin. Python-da misol: ``` import re string = "X.Y.4" pattern = re.compile{(r".[^.]*$") new_string = re.sub(pattern, "", string) print{(new_string) # Output: XY. ``` Ushbu misolda `.re{(sub`) funksiyasi stringning mos bo'lgan qismini bo'<|eot_id|>
