    input.txt
    0 m
    100 f
    180 f
    280 d
    and output.txt

    0 99 m
    100 179 f
    180 279 f
    280 blank d
    I tried this a lot but didnt get that pattern ... Please please please , somebody solve this for me

    You may notice that "second column" has "next number-1" of column first.

    Re: Please solve this program

    The code isn't beautiful... but it works

    import sys,os,msvcrt,re
    main_path = os.getcwd().replace('\\','/')
    output_text = ''
    try:
    os.remove(main_path+'/output.txt')
    except:
    pass
    print 'custom program for bittu123\n'
    try:
    file_input = open(main_path+'/input.txt', 'r')
    lines = file_input.readlines()
    line_number = 0
    output_list = []
    parsed_data = []
    for line in lines:
    line_number+=1
    parsed_data.append(re.split('\s', line.lstrip()))
    for i in range(line_number):
    output_list.append(i)
    output_list[i]=parsed_data[i]
    pos = 0
    for letter in parsed_data[i]:
    pos+=1
    if letter.isalpha():
    letter_position = pos-1
    data_len = len(parsed_data)
    if i<(data_len-1):
    element = i+1
    else:
    element = i
    if i!=(data_len-1):
    for a in parsed_data[element]:
    if a.isdigit():
    output_list[i][letter_position:letter_position]=[int(a)-1]
    letter_position+=1
    else:
    output_list[i][letter_position:letter_position]=['blank']
    except:
    print 'Opening the file has failed / No file found.'
    for w in output_list:
    for wr in w:
    output_text+=str(wr)+' '
    output_text+='\n'
    try:
    output_file = open('D:/Python27/project/output.txt','a')
    output_file.write(output_text)
    output_file.close()
    except:
    print 'Writing the file has failed.'
    file_open = raw_input('Open the output file? y/n\n')
    if file_open == 'y':
    try:
    os.startfile(main_path+'/output.txt')
    except:
    print 'File lounching has failed.'
    pass

    print '\nPress any key to exit'
    ch = msvcrt.getch()

    brutalenemy666: do not give code as a free handout. In the long run, spoonfeeding is harmful. When you do show code, post it in [code][/code] bbcode tags. This is especially essential for Python where a difference in indentation can alter the meaning of the code.

    Read the FAQ on homework. Note that "homework" is applicable even if it was not assigned to you by a teacher in an academic environment.
