# make random module resources available

# value from the range( 10, 100 )

# set dimensions of a table

#### show that a simple range-based loop

# print the row indices of the table
for r in range( 0, rows ) :
    print( "row:", r )

print()

#### show that a nested range-based loop 

# print the individual row and column indices into the table
for r in range( 0, rows ) :
    for c in range( 0, columns ) :
        print( "row:", r, "column:", c )
    print()

    # need to start a new row for the table
    row = []                        # row is set to be a fresh accumulator

    # for each column c in the new row, its value is r + c
