help regarding re.search

[Sagar Neve]

Hi,
I have a small program where I want to do just a small regex operation.
I want to see if value of a variable 'A' is present in an another variable
'B'.  The below code works fine but as soon as the variable 'A' has some
string including a dot it fails.

for example say:
B="xxxxyyyydpkg.ipazzzzz
The code works fine  when A="dpkg"
however the code does not work when A="dpkg.ipa"

if re.search(A,B):
      # do something.

Can somebody please help me ?
