regex - sort by substring in a list- Python -


i got text file containing lines separated in manner:

action: add parameter matched parameter: ctl00_contentplaceholdermain_radsearchboxneid_clientstate  on [https] /consolepage/consolepageweb.aspx matched wildcard: *   action: add parameter matched parameter: ctl00$contentplaceholdermain$hiddenfieldselectedfilter on  [https] /consolepage/consolepageweb.aspx matched wildcard: *

i've written small script in python string after "matched paramater: " , output file, results not sorted properly.

the script:

import re  pattern = "^matched parameter: ([^\s]+)" new_file = []  open(".\params.txt") txtfile:     lines = txtfile.readlines()  line in lines:     match = re.search(pattern, line)     if match:         new_line = match.group()        new_line = new_line.split(" ")     del new_line[0], new_line[0]     new_line = sorted(new_line)     print(new_line)

output: 

['ctl00_mainsplitter_clientstate'] ['ctl00_radwindowlicenseaggreemennt_c_radbuttonlicenseaggreemenntcancel_clientstate'] ['ctl00_radwindowlicenseaggreemennt_c_radbuttonlicenseaggreemenntok_clientstate'] ['ctl00_radwindowlicenseaggreemennt_clientstate'] ['ctl00$scriptmanagermain'] ['ctl00_radstylesheetmanager1_tssm'] ['ctl00_scriptmanagermain_tsm'] ['__viewstate'] ['ctl00_radwindow1_clientstate'] ['ctl00_radbuttonlgout_clientstate'] ['ctl00_toppane_clientstate'] ['ctl00_radpanelbarmainmenu_clientstate'] ['ctl00_leftpane_clientstate'] ['ctl00_contentplaceholdermain_radwindowmanager1_clientstate'] ['ctl00$contentplaceholdermain$radcomboboxtimeresolution'] ['ctl00_contentplaceholdermain_radcomboboxtimeresolution_clientstate'] ['ctl00_contentplaceholdermain_radsearchboxneid'] ['ctl00_contentplaceholdermain_radsearchboxneid_clientstate'] ['ctl00$contentplaceholdermain$hiddenfieldselectedfilter'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radbuttonalarmsfilterclose_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxrulenames_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxseverity_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxstatus_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxentitytype_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radbuttonalarmsfilterok_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowfilterslist_c_radbuttonfilterslistclose_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowfilterslist_c_radlistboxexistingfilters_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowfilterslist_c_radbuttonfilterslistok_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowfilterslist_c_radbuttonfilterslistedit_clientstate']

i need output sorted it's parameter name substring in alphabetical order, example 'alarmsuserfilters' before 'clientstate':

['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radbuttonalarmsfilterclose_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxrulenames_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxseverity_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxstatus_clientstate'] ['ctl00_contentplaceholdermain_alarmsuserfilters_radwindowalarmsfilter_c_radlistboxentitytype_clientstate'] ['ctl00_mainsplitter_clientstate']

any how in best possible way?, need generic possible, i.e there different strings need sorted way('ct100' etc.. 1 example)

thanks!

as others have pointed out, problem you're building list of length 1, sorting printing before reading whole file. i've changed code this:

import re  pattern = "matched parameter: ([^\s]*)" parameters = []  open(".\\params.txt") txtfile:     line in txtfile:         match = re.match(pattern, line)         if match:             parameters.append(match.group(1))  par in sorted(parameters):     print(par)

it should work fine. has changed other bits , pieces bit - match.group(1) gets matched group, bit in parentheses () in regex. also, want match start of line, can use re.match. i'm iterating on lines of file directly, rather building lines , iterating on those. note correct in entirely possible use sort , sorted on list of strings, python compares them 'alphabetically', called 'lexicographically'.

unfortunately might struggle provide meaningful sample output without spending ages reconstructing input, don't have access it.

arrays - What causes a java.lang.ArrayIndexOutOfBoundsException and how do I prevent it? -

what arrayindexoutofboundsexception mean , how rid of it? here code sample triggers exception: string[] name = {"tom", "dick", "harry"}; for(int = 0; i<=name.length; i++) { system.out.print(name[i] +'\n'); } your first port of call should documentation explains reasonably clearly: thrown indicate array has been accessed illegal index. index either negative or greater or equal size of array. so example: int[] array = new int[5]; int boom = array[10]; // throws exception as how avoid it... um, don't that. careful array indexes. one problem people run thinking arrays 1-indexed, e.g. int[] array = new int[5]; // ... populate array here ... (int index = 1; index <= array.length; index++) { system.out.println(array[index]); } that miss out first element (index 0) , throw exception when index 5. valid indexes here 0-4 inclusive. correct, idiomatic for statement here be: for (int index = 0; index <...
