It is a question of finding and returning the address of the lot number and road name by Python regular expression.

For example, in the sentence 'I live in 338 Samseong-dong, Yongsan-gu, Seoul'

I'm going to solve the problem of finding '338 Samseong-dong, Yongsan-gu, Seoul'.

You should be able to find it with a street name address I'm worried because I have to find some empty addresses.

I'm going to search for the street name address and lot number address at the same time

regex = r'(\w+[City, Province]\s*)?(\w+[Old, City, County]\s*?(\w+[Old, City]\s*)?(\w+[Myeon, Eup]\s*)?(\w+\d*\w*[Dong, ri, ro, road]\s*)?(\w*\d+-?\d*)?'

You entered the regex variable in the form of

test = 'I live in 338 Samseong-dong, Yongsan-gu, Seoul'

After you type

x = re.search(regex, test) x.group() If you do this

``This is the result.

test = 'I live in 338 Samseong-dong, Yongsan-gu, Seoul'

If you proceed to , you will find the address exactly address.

I think all the regular expressions in regex are optionally given as ?, so the first value you look for is blank, but I don't know how to exclude it. What should I do?
