python: exit out of two loops

Question

  for row in b:     for drug in drug_input:       for brand in brand_names[drug]: 

from the third loop how do i exit the current loop and go to the next value of for row in b: ?

Answer 1

This one uses a boolean to see if you are done yet:

done = False for x in xs:     for y in ys:         if bad:             done = True             break      if done:         break 

This one will continue if no break was used. The else will be skipped over if there was a break, so it will see the next break. This approach has the benefit of not having to use a variable, but may be harder to read to some.

for x in xs:     for y in ys:         if bad:             break     else:         continue      break
