python multiplication tables with while loops with different starting int -

-

i need homework. want me make 10x10 multiplication tables using multiple while loops , nesting. want user prompted first number row , column. if give 3 column , 12 row this:

       3    4    5    6    7    8    9   10   11   12    -------------------------------------------------- 12|   36   48   60   72   84   96  108  120  132  144 13|   39   52   65   78   91  104  117  130  143  156 14|   42   56   70   84   98  112  126  140  154  168 15|   45   60   75   90  105  120  135  150  165  180 16|   48   64   80   96  112  128  144  160  176  192 17|   51   68   85  102  119  136  153  170  187  204 18|   54   72   90  108  126  144  162  180  198  216 19|   57   76   95  114  133  152  171  190  209  228 20|   60   80  100  120  140  160  180  200  220  240 21|   63   84  105  126  147  168  189  210  231  252

this found internet search help:

row = int(input("enter first row number: " )) while(row <= 10):     column = int(input("enter frist column number: "))     while(column <= 10):         if(row+column==0):             print('{:4s}'.format(''),end = '') #corner         elif(row*column==0):             print('{:4d}'.format(row+column),end = '') # border         else:             print('{:4d}'.format(row*column),end = '') # table         column=column+1        print()     row=row+1

if me thankful

it should more this:

row1 = int(input("enter first row number: " )) column1 = int(input("enter first column number: "))  # todo: print header  row in range(row1, row1 + 10):     column in range(column1, column1 + 10):         # todo

that is, prompt input twice, not (1+n) times, , use built-in function range() generate lists of rows , columns iterate over.
