Not in a situation to be able to test this so you may need to fiddle with the Regular Expression (they may be errors in it.)
import re
re.sub("SSViewer::set_theme\('[a-z]+'\)", "SSViewer::set_theme('whatever')", my_string)
Is this what you want?
Just tested it, this is some sample output:
my_string = """Some file with some other junk
SSViewer::set_theme('bullsorbit');
SSViewer::set_theme('another');
Something else"""
import re
replaced = re.sub("SSViewer::set_theme\('[a-z]+'\)", "SSViewer::set_theme('whatever')", my_string)
print replaced
produces:
Some file with some other junk
SSViewer::set_theme('whatever');
SSViewer::set_theme('whatever');
Something else
if you want to do it to a file:
my_string = open('myfile', 'r').read()

thank u for reply .. it is file .. i want read file and search for that string and replace what ever
AutomatedTester
That will replace everything with
my_string. Check this by running it in the interactive consolerajaneesh
import re file_read = open("/var/www/rajaneesh/mysite/_config.php", "r") contents = file_read.read() file_read.close() this my code i want search that string "SSViewer::set_theme('whatever')" file and replace that string with new string

You want to find 'bullsorbit' from the pattern "SSViewer::set_theme('bullsorbit');" and replace all occurrences of 'bullsorbit' thereafter with another string? Is that what you are asking?
kjfletch
Be clear that this only works for lower case [a-z] If you want it to catch other characters you will need to tweak the regular expression.
>> my_string = "SSViewer::set_theme('bullsorbit');"
>>> import re
>>> change = re.findall(r"SSViewer::set_theme\('(\w*)'\);",my_string)
>>> my_string.replace(change[0],"blah")
"SSViewer::set_theme('blah');"
its not elegant but it works. the findall will return a dictionary of items that are inside the ('') and then replaces them. If you can get sub to work then that may look nicer but this will definitely work

Consider this: "SSViewer::set_theme('theme')" would be replaced with "SSViewer::set_blah('blah')"
st = "SSViewer::set_theme('"
for line in open("file.txt"):
line=line.strip()
if st in line:
a = line[ :line.index(st)+len(st)]
b = line [line.index(st)+len(st): ]
i = b.index("')")
b = b[i:]
print a + "newword" + b

while your explanation is not entirely clear, I think you might make some use of the following:
open(fname).read().replace('bullsorbit', 'new_string')

i thought he meant bullsorbit is changing dynamically, so the above might not be what he needs.
SilentGhost
what exactly changing dynamically means? run it with another string,
'bullsorbit2'.
