you should use a list as you do...

I don't have your map so I'm not able to reproduce the problem on my 

I've try with:
from grass.pygrass.modules.shortcuts import imagery as i

alb = i.albedo
alb(input=['b1', 'b2', 'b3', 'b4', 'b5', 'b7'], 
    output='b_albedo', flags="lc", overwrite=True, run_=False)

and return 'i.albedo input=b1,b2,b3,b4,b5,b7 output=b_albedo -l -c --o'
that it seems correct to me...

Can you provide some more details about "b_in does not work"? :-)
What kind of error do you have?

Best regards


ps: thank you for testing!
