사전 컴파일 및 반복

Question

저는 파이썬에 처음으로 익숙하며 파일에서 사전을 작성한 다음 사전을 반복합니다. 나는 일식에서 일해 왔으며 출력이나 경고를받지 못하고있다.

import re 

id_to_info = {} #declare dictionary 

def parse_record(term): 
    go_id = re.findall(r"id:\s(.*?)\n", term, re.DOTALL) 
    name = re.findall(r"name:\s(.*?)\n", term, re.DOTALL) 
    namespace = re.findall(r"namespace:\s(.*?)\n", term, re.DOTALL) 
    is_a = re.findall(r"is_a:\s(.*?)\n", term, re.DOTALL) 
    info = namespace + "\n" + name + "\n" + is_a 
    id_to_info[go_id] = info 
    for go_id, info in id_to_info.interitems(): 
     print(go_id + "\t" + info) 

def split_record(record): 
    sp_file = open(record) 
    sp_records = sp_file.read() 
    sp_split_records = re.findall(r"(\[.*?)\n\n", sp_records, re.DOTALL) 
    for sp_record in sp_split_records: 
     parse_record(term=sp_record) 
    sp_file.close() 

split_record(record="go.rtf")

어디서 잘못 가고 있는지 모르겠지만 주요 문제는 사전 호출이라고 생각하고 있습니까?

Answer 1

re.findall 발견 된 항목의 목록을 반환합니다. 귀하의 코드는 문자열을 가정합니다. 한 줄에 하나의 히트가 있기 때문에 가능한 경우 [0]을 추가하십시오. is_a이 비어있을 수 있으므로 좀 더 부드러운 처리가 필요합니다.

또한, (키 값) 방법 iteritems (반복 항목)하지 I N teritems이다.

여기 업데이 트입니다 :

import re 

id_to_info = {} #declare dictionary 

def parse_record(term): 
    go_id = re.findall(r"id:\s(.*?)\n", term, re.DOTALL)[0] 
    name = re.findall(r"name:\s(.*?)\n", term, re.DOTALL)[0] 
    namespace = re.findall(r"namespace:\s(.*?)\n", term, re.DOTALL)[0] 
    is_a = re.findall(r"is_a:\s(.*?)\n", term, re.DOTALL) 
    is_a = is_a[0] if is_a else "" 
    # print namespace, name, is_a 
    info = namespace + "\n" + name + "\n" + is_a 
    id_to_info[go_id] = info 
    for go_id, info in id_to_info.iteritems(): 
     print(go_id + "\t" + info) 

def split_record(record): 
    sp_file = open(record) 
    sp_records = sp_file.read() 
    sp_split_records = re.findall(r"(\[.*?)\n\n", sp_records, re.DOTALL) 
    for sp_record in sp_split_records: 
     parse_record(term=sp_record) 
    sp_file.close() 

split_record(record="go.rtf") 

출력 :

trans-hexaprenyltranstransferase activity 
GO:0016765 ! transferase activity, transferring alkyl or aryl (other 
GO:0000011 biological_process

내가 당신에게 형식의 나머지 부분을 떠날거야. :-)

는 또한 인쇄를 많이 넣어, 파이썬은 그렇지 않은 의미, 동적 컴파일하고 실행하십시오. 오류가 발생할 때까지 실행됩니다.

귀하의 문제 :

1) 정규식 - 구글 주위 2) 오타 - iteritems! 둘 다 Python doc에서 읽을 수 있습니다. 그들은 정말 좋습니다 .. 또는 어떤 책을 선택하십시오. 코드를 작성하고 통역사를 실험하면서 많은 것을 배우게됩니다.
