python - Looping through a folder to merge several excel sheets into one column -

-

i have several workbooks, each 3 sheets. want loop through each workbook , merge data sheet_1 new workbook_1 file, sheet_2 workbook_2 file & sheet_3 workbook_3.

as far can tell script below need, except rather appending data, overwrites data previous iteration.

for sake of parsimony i've shortened, cleaned & simplified script, i'm happy share full script if needed.

import pandas pd import glob  search_dir= ('/users/path/*.xlsx')  sheet_names = ['sheet_1','sheet_2','sheet_2']  def a_joiner(sheet):     loop_x in glob.glob(search_dir):        try:          if sheet == 'sheet_1':             id_file= pd.excelfile(loop_x)                                         df_1 = id_file.parse(sheet, header= none)                          writer= pd.excelwriter('/users/path/%s.xlsx' %(sheet), engine= 'xlsxwriter')                                      df_1.to_excel(writer)                                 writer.save()          elif sheet == 'sheet_2':            #do same above          else:            #and same above again      except exception e:        print('error:',e)  sheet in sheet_names:     a_joiner(sheet)

you can easilly append data like:

df = [] f in ['c:\\file1.xls', 'c:\\ file2.xls']:     data = pd.read_excel(f, 'sheet1').iloc[:-2]     data.index = [os.path.basename(f)] * len(data)     df.append(data)  df = pd.concat(df)

from: using pandas combining/merging 2 different excel files/sheets

java - Static nested class instance -

this question has answer here: java inner class , static nested class 23 answers i came across in java, know static nested class why create instance of 'static'. isn't whole idea of 'static' use without instance? understand concept of inner classes, why (and frankly how possible to) create 'instance' of 'static' member @ ? why this: 1- outerclass.staticnestedclass nestedobject = new outerclass.staticnestedclass(); 2- nestedobject.anestedclassmethod(); and not this: 1- outerclass outerinstance=new outerclass(); 2- outerinstance.staticnestedclass.anestedclassmethod(); use on inner classes, keyword static indicates can access inner class without instance of outer class. for example: public class outer { public static class inner { /* code here. */ } } with construction, can create instance of inn

JavaScript - Replace variable from string in all occurrences -

ok, know if have character '-' , want remove in places in string javascript, ... someword = someword.replace(/-/g, ''); but, when applying array of characters, s not working ... const badchars = ('\/:*?"<>|').split(''); let filename = title.replace(/ /g, '-').tolocalelowercase(); (let item = 0; item < badchars.length; item++) { // below not work global '/ /g' filename = filename.replace(/badchars[item]/g, ''); } any ideas? /badchars[item]/g looks badchars , literally, followed i , t , e , or m . if you're trying use character badchars[item] , you'll need use regexp constructor, , you'll need escape regex-specific characters. escaping regular expression has been well-covered . using that: filename = filename.replace(new regexp(regexp.quote(badchars[item]), 'g'), ''); but , don't want that. want character class: let filename = title.replac
