Why does the leading 'a' change to a 'c'? Is that a mistake? I'll assume its a
typo.
You want string slicing.
base = 'a'
extra = 'ab'
print( base[:-len(extra)] + extra

Why would you expect that? Concatenation means "joining together", so

'foobar'
No other mangling of either of your original strings is going to happen;
there is no magic going on here.

I have a config file with the following contents:
service A = {
params {
dir = "c:\test",
username = "test",
password = "test"
}
}
I want to find username and replace the value with another value. I
don't know what the username value in advance though. How to do it in
python?

If 'a' and 'b' are different length,
- Count the string length, before and after. The difference should
be multiple of difference between length of 'a' and 'b'.

The count isn't returned by the replace method. You'll have to count
and then replace.
def count_replace(a, b, c):
count = a.count(b)
retur
if i have
mytext.replace(a,b)
how to find out many many occurances has been replaced?

You misunderstand me. I don't have a problem with lambda when it's
appropriate, e.g. when used as an expression, where a statement is
forbidden
Alright, now it's too much. It's not enough that you're eliminating it

See "Inappropriate use of Lambda" in

You're creating a named function, so there's no reason to use the
anonymous function syntax. Try:

return (x[
I can't claim to have studied your problem in detail, but I get
reasonable results from the following:
filename = 'Errors.txt'
S = open(filename,'r').read().split()
f = lambda x: (x[0]=='@' and x[6:] + '.0') or (x=='/' and x + '\n') or
x
open(filename,'w').write(' '.join(map(f,S)))

Hello Peter And NG,
thank you a lot... now I'm blaming myself, how couldn't I see it? I
will probably go for the re.sub (if it is not too complicated, I'm not a
Python expert and even less expert of RegEx things), if not I'll try your
suggestion of sorting the strings by length.
Thanks a lo
