Count number of values

[Kristenl2784]

Hello,

How would I go about reading ws1 column F starting at row 4 and counting the number of times the value 0 occurs and then write that number to ws3 column M row 2?

import openpyxl as xl; 
import os


input_dir = 'C:\\work\\comparison\\NNM'
template = 'C:\\work\\comparison\\template.xlsx'
summary = 'C:\\work\\comparison\\summary.xlsx'
newFile = 'Comparison.xlsx'




files = [file for file in os.listdir(input_dir)
         if os.path.isfile(file) and file.endswith(".xlsx")]


wb3 = xl.load_workbook(template) 
ws3 = wb3.worksheets[0] 

i=0
ii=0


for file in files: 
   input_file =  os.path.join(input_dir, file)
   wb1=xl.load_workbook(input_file)
   ws1=wb1.worksheets[0]

   
   wb2 = xl.load_workbook(summary) 
   ws2 = wb2.worksheets[1]

    
   ws3[f'A{i+2}']=ws1['A1'].value[28:]
   ws3[f'D{i+2}']=ws1['B4'].value
   ws3[f'E{i+2}']=ws1['D4'].value
   ws3[f'I{i+2}']=ws1['B'][-1].value
   ws3[f'J{i+2}']=ws1['D'][-1].value
   ws3[f'O{i+2}']=ws1['E'][-1].value 
   ws3[f'N{i+2}']=ws2[f'I{ii+6}'].value   
   i += 1
   ii +=1          
   
   

   wb3.save(newFile)
