💎Regex İşlemleri

Python regex kütüphanelerini kullanma

📦 Regex Paketi re Kullanımı

Fonksiyon	Açıklama
split(<regex>, <string>)	Birden fazla karaktere göre parçalama
`sub(, <replace	metot>, )`
compile(<regex>, <?flag>)	Regex objesi oluşturma

‍🧙‍♂ Regex objesi oluşturulduğunda tekrar tekrar regex tanımlaya gerek yoktur

💠 Regex için Metot Oluşturma

color_regex = re.compile("#([0-9a-fA-F]{6,8})", re.IGNORECASE)

def my_method(content):
    text = content.group().lower()

content = color_regex.sub(my_method, content)

result = re.search(r"\[([^\[]+)\]\((.*)\)", "- [name](url)")
result[0] # '[name](url)'
result[1] # 'name'
result[2] # 'url'
