Versus-ni qidirish

Python oddiy iboralar asosida ikkita turli xil ibtidoiy operatsiyalarni taklif qiladi

: matchni faqat satr boshida tekshirish, a ni qidirish

satrning istalgan joyiga moslashtiring (bu Perlning odatiy holati).

Misol

#! / usr / bin / python3

import re

line = "Mushuklar itlarga qaraganda aqlli";

matchObj = re.match (r'dogs ', qator, re.M | re.I)

agar matchObj:

chop etish ("match -> matchObj.group ():", matchObj.group ())

yana:

chop etish ("Hech narsa topilmadi !!")

searchObj = re.search (r'dogs ', qator, re.M | re.I)

agar qidiruvObj:

363-sahifa

Python 3

350

chop etish ("qidirish -> searchObj.group ():", searchObj.group ())

yana:

bosib chiqarish ("Hech narsa topilmadi !!")

Yuqoridagi kod bajarilganda, u quyidagi natijani beradi -

Hech narsa topilmadi !!

qidiruv -> matchObj.group (): itlar
