Question

I need python help .. I need to know if a user were to input 3 commands to a program and run it such as specify:

Usage: ./filemaker INPUTCOMMANDFILE OUTPUTFILE RECORDCOUNT
(./filemaker is the program)( (INPUTCOOMANDFUILE= a text file that contains key words that need to be searched through then decided what to do ) (RECORDCOUNT= number)

Given an input file that contains the following: That specifies the text, then the output, and the number of times to be repeated

for example: Scenario: Script supports the HEADER command
Given a file named "headercmd" with:
"""
HEADER "THIS IS A \t\t\tHEADER\n"
STRING "just a string\n"
"""
When I run `../bin/filemaker headercmd headeroutput 2`
Then the file "headeroutput" should contain:
"""
This is a header
just a string
just a string
"""

so it will search through the text file, find the key word "header" then print out that header command once

then it will read the keyword STRING and print what comes after the keyword and loop that number of times specified by the user input.. this is the code I have right now..

import sys
import re


# read command line arguments
inpFile = "in.txt"
outFile = "out.txt"
outFile2 = "out2.txt"
count = 3

# Open output file in write mode
out = open(outFile,'w')

# f=open(inpFile,'r')
# l=f.readlines()
# l[0]
# f3=open(outFile2,'w')
# f3.write(l[0].decode('string_escape'))
# print(f3)

with open(inpFile) as f: # for each line
    for line in f: # if there is word STRING in line
        if "HEADER" in line: # Writing to out file # multiplying by count for printing multiple times
            out.write(str(re.findall(r'"(.*?)"', line, re.DOTALL)[0]).replace('\\n', '\n'))


# closing the out file




# read input file
with open(inpFile) as f: # for each line
    for line in f: # if there is word STRING in line
        if "STRING" in line: # Writing to out file # multiplying by count for printing multiple times
            out.write('"""')
            out.write('\n')
            out.write(str(re.findall(r'"(.*?)"', line, re.DOTALL)[0]).replace('\\n', '\n') * count)
            out.write('"""')

# closing the out file
out.close()

out.txt

out.txt * 1 THIS IS A HEADER 4 just a string 5 just a string 6 just a string 7just a string

Note: if have you have \t in file then you shoud replace with \t then it will work beacuse when you read "\t" treated as string but when you replace with "\t" its treated as whitespace

if any doubt please comment (its confusing )
