In line no. 7 i.e outside from the for “j” loop. There should be 1 tab space (i.e 4 spaces)
but it seems that you have written only 2 spaces.
So, Here is a sol. whether u can increase the space upto 4 or delete all the spaces before the print statement and press Shift it will automatically add 1 tab space that is needed to solve your problem!
