Open Python IDLE and paste the code given below

Change the path given in project for infile and outFile

-------------------------------------------------------------------------------------------------------------------

def main():
#read file from path
infile = open("C:\\Users\\PhoenixZone\\Desktop\\testfile.txt","r")
lines_list = infile.readlines()
infile.close()
#file to write the data
outFile = open("C:\\Users\\PhoenixZone\\Desktop\\outfile.txt","w+")
for line in lines_list:
#Get rid of each line of numbers that is not 8 characters long
if len(line)>8:
#Get rid of lines that don't begin with (478, 932, 188, 642, 093)
if line.startswith('478') or line.startswith('932') or line.startswith('188') or line.startswith('642') or line.startswith('093'):
#write line to output.txt
outFile.write(line)
  
main()
