How to jump out of nested 'for'-loops?

[Peng Yu]

Hi,

I want some command to jump out of nested loop. I'm wondering what is
the most convenient way to do so in python.

for i in range(10):
  print "i = ", i
  for j in range(10):
    if i*10 + j == 50:
      print i*10 + j
      break # I want to jump out of the loops.

Regards,
Peng
