How do I ask the webserver if a file exists based on a wildcard

This is the continuation of question

How to use python regular expression inside if... else... statement?

My Python script:

import wget

if windowsbit == x86:
    url = 'http://test.com/test_windows_2_56_30-STEST.exe'
    filename = wget.download(url)
else:
    url = 'http://test.com/test_windows-x64_2_56_30-STEST.exe'
    filename = wget.download(url)

url contains only two files. one is for 32 bit and another is for 64 bit. I mean always the old files with be deleted and only new files will be there in that url. Always 32 bit file will start with test_windows and ends with STEST.exe . And 64bit file will start with test_windows-x64 and ends with STEST.exe .

Could anyone guide me on writing wildcard or regexp?

If you want to check the url and it is always in that format, you just need to check if it startswith "test_windows-x64" after splitting:

if url.rsplit("/", 1)[1].startswith("test_windows-x64"): 
           # do whatever
else:
    # it is 32 bit

If you really need to check the ending:

base = url.rsplit(None,1)[1]
if base.startswith("test_windows-x64") and base.endswith("STEST.exe")
