Hi,
I am new to python and i wrote this piece of code which is ofcourse not
serving my purpose:
Aim of the code:
To read a file and look for lines which contain the string 'CL'. When
found, print the entry of the next line (positioned directly below the
string 'CL') ....continue to do this till the end of the file (since
there are more than one occurrences of 'CL' in the file)
My piece of code (which just prints lines which contain the string 'CL')
f=open('somefile.txt','r')
for line in f.readlines():
if 'CL' in line:
print line
please suggest how do i print the entry right below the string 'CL'
Will "the next line" ever contains "CL"? And if it does, should we print
the next, next line. That is, in case of:
abcCLdef
ghiCLjkl
mnopqrst
should we print:
ghiCLjkl
mnopqrst
or:
ghiCLjkl
if the latter is the case, then you can advance the file's cursor:
with open('myfile.txt') as f:
for line in f:
if 'CL' in line:
print next(f)
