Hello all,
query 1) How should i overwrite the input file
I want to open 5 files one by one, do some operation on the lines and write
the modified lines on the same file (overwritting). Can some please tell me
how to do it.
pat1=" R"
pat2="U5"
pat3="A3"
from sys import argv
files=argv[1:]
for names in files:
out=open(names + '_new','w') # Here i creat new files to write the
content which i dnt want
for line in open(names):
if pat1 in line:
line=line.replace(pat1," ")
if pat2 in line:
line=line.replace(pat2,"U ")
if pat3 in line:
line=line.replace(pat3,"A ")
out.write(line)
query 2) How should I use wild cards to open files in python. Say I have
files with names *.dat in a directory, i want the program to open every
file with extension .dat and do the process.
Thanks in advance,
Bala
