How can I change the output of this function into a dictionary?-CodePudding

I have written a function containing regex to separate some special parts of a txt file. The code works fine but I would like to get a dictionary as an output from this and the length should be 979:

import re

def logs():
    with open("C:/Users/ASUS/Desktop/logdata.txt", "r") as file:
        logdata = file.read()

    pattern = ''' 
    (?P<host>\d{1,}\.\d{1,}\.\d{1,}\.\d{1,})   # host name
    \s \S \s 
    (?P<user_name>(?<=-\s)(\w |-)(?=\s))\s \[   # user_name
    (?P<time>([^[] ))\]\s "   # time
    (?P<request>[^"] )"   # request
    '''

    for item in re.finditer(pattern, logdata, re.VERBOSE):
        print(item.groupdict())

This function is supposed to turn a text like this:

146.204.224.152 - feest6811 [21/Jun/2019:15:45:24 -0700] "POST /incentivize HTTP/1.1" 302 4622

to this capturing host, user_name etc:

{"host":"146.204.224.152", 
 "user_name":"feest6811", 
 "time":"21/Jun/2019:15:45:24 -0700",
 "request":"POST /incentivize HTTP/1.1"}

How can I do this?

I managed to fix this issue by making the following modifications:

def logs():
    with open("C:/Users/ASUS/Desktop/logdata.txt", "r") as file:
        logdata = file.read()

    pattern = ''' 
    (?P<host>\d{1,}\.\d{1,}\.\d{1,}\.\d{1,})   # host name
    \s \S \s 
    (?P<user_name>(?<=-\s)(\w |-)(?=\s))\s \[   # user_name
    (?P<time>([^[] ))\]\s "   # time
    (?P<request>[^"] )"   # request
    '''

    dict = {}
    for item in re.finditer(pattern, logdata, re.VERBOSE):
        dict[item] = item.groupdict()

    return dict

type(logs())
<class 'dict'>

CodePudding user response：

is this the result you wanted?

import re

def logs():
    with open("C:/Users/ASUS/Desktop/logdata.txt", "r") as file:
        logdata = file.read()

    pattern = ''' 
    (?P<host>\d{1,}\.\d{1,}\.\d{1,}\.\d{1,})   # host name
    \s \S \s 
    (?P<user_name>(?<=-\s)(\w |-)(?=\s))\s \[   # user_name
    (?P<time>([^[] ))\]\s "   # time
    (?P<request>[^"] )"   # request
    '''

    match_object = re.match(pattern, logdata)
    details = match_object.groupdict()
    print(details)
