for i in range( 5 ): for j in range( 3 ): print i+j, print
for i in range( 3 ): print '-' * i
for i in range( 4 ): for j in range( i ): print j * '-'
Exercise 2
Write the code necessary to take the string "jan31feb28mar31apr30" and generate the following output from it:
jan 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 29 30 31 feb 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 mar 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 29 30 31 apr 1 2 3 4 5 6 7 8 9 10 11 ... 27 28 29 30
