python - Is there a way to add multiple conditions in a for loop? -

    n=int(raw_input('enter number of mcnuggets want buy : ')) #total number of               mcnuggets want yo buy     in range(1,n) , b in range(1,n) , c in range(1,n) :         if (6*a+9*b+20*c==n):             print 'number of packs of 6 ',a             print 'number of packs of 9 ',b             print 'number of packs of 20 are',c 

i new programming , learning python.the code above gives errors. suggestion.?.

you should use nested loops:

for in range(1, n):     b in range(1, n):         c in range(1, n):             if ... 

or better:

import itertools  a, b, c in itertools.product(range(1, n + 1), repeat=3):     if ...
