List,

I try to assign value to force_mcs sitting in a wildcard subdirectory 
/sys/kernel/debug/ieee80211/phy*, but python does not work for that such as:

os.system("echo %i > /sys/kernel/debug/ieee80211/phy*/iwlagn/data/force_mcs" % 
mcs)

Any right way to do it?

Don't use os system. Use subprocess. Which incidentially is mentioned in the docs for os.system:

  http://docs.python.org/library/os.html#os.system

Then you can pass the "use_shell=True" parameter - which should work in your case.
