Pattern-ите, които съм дефинирала в началото на файла не ми харесват, но не можах да направя по-добри. Не е хубаво да са толкова сложни и нечетими нали? И не знам ли дали може да ми помогнете, но не успях да намеря как да ползвам част от един pattern в друг, например INT_PHONE_PATTERN има еднаква част с LOC_PHONE_PATTERN.

  • Използвай \b
  • Валидаторите ти трябва да връщат True или False
  • Променливата ти config е дефинирана в if-a, а я използваш извън него, което може да ти създаде проблеми в някои случаи
  • А за да ги използваш, можеш да работиш с тях като със стрингове

" И не знам ли дали може да ми помогнете, но не успях да намеря как да ползвам част от един pattern в друг, например INT_PHONE_PATTERN има еднаква част с LOC_PHONE_PATTERN."

Цвети, така няма ли да стане :

PHONE_PATTERN='(([1-9](\s|\-|\(|\)){,2}){6,10}'

INT_PHONE = r'(00|\+)[1-9]{1,3}'+PHONE_PATTERN+'\d)$'

LOCAL_PHONE = r'0'+PHONE_PATTERN+'\d$'
