how to make loop within loop go back to first loop

I have the a program to print items from lists within lists in a specific way. Here is that piece of code:

 for y in range(0,5):      
     print '\n'
     for x in tableau:
          if y < len(x):
           print x[y],
          else :
              print '   '

What I want is for the if statement go back to the inner loop(for x in tables) after it executes the print ' ' in the else part of if statement. Is there any way to do that?

As suggested by Delgan, the answer is staightforward - you have to use the break keyword :

 for y in range(0,5):      
     print '\n'
     for x in tableau:
          if y < len(x):
           print x[y],
          else :
              print '   ' 
              break

The break keyword exits the most inner loop.

 print '\n'
 for x in tableau:
      if y < len(x):
       print x[y],
      else :
          print '   '
          break

Will break out of the inner for and back into the outer for, after the print is executed. This will print a "\n" and then move back to the inner for, which I believe is what you are asking?

As I don't really understand what you need, I suggest you 2 solutions
First one: print ' ' instead of inexistent list element (3 times if len(x) == 2)

for x in tableau:
    print '\n'
    for y in x:
        print y
    for y in range(5 - len(x))
        print '   '

Second one: print ' ' always at the end of the list

for x in tableau:
    print '\n'
    for y in x:
        print y
    print '   '
