Python 编译和迭代字典

我对python相当陌生，正在从一个文件构建一个字典，然后迭代字典。我一直在eclipse中工作，没有收到任何输出，甚至没有收到任何警告

输入如下所示（实际输入显著增大）

我试图产生的结果是

GO:0000010     molecular_function
trans-hexaprenyltranstransferase activity
GO:0016765 ! transferase activity, transferring alkyl or aryl (other than methyl) groups

GO:0000011    biological_process
vacuole inheritance
is_a: GO:0007033 ! vacuole organization
is_a: GO:0048308 ! organelle inheritance

GO:0000012    biological_process
single strand break repair
is_a: GO:0006281 ! DNA repair

GO:0000014    molecular_function
single-stranded DNA endodeoxyribonuclease activity
is_a: GO:0004520 ! endodeoxyribonuclease activity

我的密码是：

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")

我真的不知道我错在哪里，但我想主要的问题是我的字典调用

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:(.*)', term, re.DOTALL)[0]
    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")

我建议不要使用IDE，而是使用终端或 至少要调试解释器：

Python 2.7.10 (default, Jul 30 2016, 18:31:42) 
[GCC 4.2.1 Compatible Apple LLVM 8.0.0 (clang-800.0.34)] on darwin
Type "help", "copyright", "credits" or "license" for more information.
>>> s = """[Term]
... id: GO:0000010
... name: trans-hexaprenyltranstransferase activity
... namespace: molecular_function
... def: "Catalysis of the reaction: all-trans-hexaprenyl diphosphate + isopentenyl diphosphate = all-trans-heptaprenyl diphosphate + diphosphate." [KEGG:R05612, RHEA:20839]
... subset: gosubset_prok
... xref: KEGG:R05612
... xref: RHEA:20839
... is_a: GO:0016765 ! transferase activity, transferring alkyl or aryl (other than methyl) groups"""
>>> import re
>>> re.findall(r'is_a:(.*)', s)
[' GO:0016765 ! transferase activity, transferring alkyl or aryl (other than methyl) groups']

此外，Python是动态的，这意味着它不需要编译和运行。。它将一直运行到出错为止

您的问题：

1） 正则表达式-谷歌漫游 2） 打字错误！你们都可以阅读 Python文档。他们真的很好。。或者随便挑一本书。。你会学到很多 在编写代码和在解释器上进行实验时进行了大量操作

re.findall返回它找到的东西的列表；您的代码假定为字符串。因为每行只有一次点击，所以只要在可行的地方添加[0]is_a可以空回来，因此需要更细致的处理

此外，（键，值）方法是iteritems（迭代项），而不是iteritems

以下是最新消息：

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")

输出：

id\u to\u info.interitems（）：

不会剪切它。请尝试

id\u to\u info.items（）：

您的代码在此处为我崩溃：

info=namespace+“\n”+name+“\n”+是\u a

，因为

是\u a

是一个列表。。。。你实际得到了什么样的输出？如何从列表中转换is_a是最好的方法？我尝试了“”。join（是a），但它仍然没有向\u info提供任何输出或错误

id\u。interitems（）：
