Python Application 1 - Format File Content

Step 1

Open any text editor (gedit,pico,vi,nano) then enter the following python script and save the file with .py extension.

#!/usr/bin/python

#Author : Jijo K Jose
input_file = raw_input("\nEnter input file name : ")
output_file = "file_new.txt"
h1 = open(input_file,"r")
print "\n----------------------------"
print "Input File Content"
print "----------------------------\n"
for i in h1:
 print i,

h1.close()
h1 = open(input_file,"r")
h2 = open(output_file,"w")
k=0
for i in h1:
 i2 = i.split(',')
 for j in i2:
  n = len(j)
  if j[n-1] =="\n":
   h2.write(j)
 else:
  h2.write(j)

  h2.write("\n")

h1.close()

h2.close()

print "\n---------------------------"

print "Output File Content - file_new.txt"
print"----------------------------\n"
h1 = open(output_file,"r")
for i in h1:
 print i,
print "\n---------------------------\n"
#END

The file contents are

123,45,78965,54545746423,546545423123
