The problem with Python exercises is as follows:Summary: The bonus paid by the enterprise is based on the profit commission. Profit (I) less than or equal to $100,000, the bonus can be raised by 10%, the profit is higher than $100,000, less than $200,000, the portion of less than 100,000 yuan by 10% commission, higher than the portion of 100,000 yuan, a commission of 7.5%, 200,000 to 400,000, higher than 20

-coordinate. Copy the previous grid values, write the code to print out the image ... Oo. Oo... Ooooooo. Ooooooo ... Ooooo ..... Ooo....... O.... Tip: You need to use loop nesting loops, print out grid[0][0], then grid[1][0], then grid[2][0], and so on, until Grid[8][0]. This completes the first line, so the next line is printed. The program will then print out grid[0][1], then grid[1][1], then grid[2][1], and so on. The program finally prints out grid[8][5]. Also, if you do not want to autom

sometimes referred to as "The simplest, impossible mathematical problem". Remember to convert the return value of input () to an integer using the INT function, or it will be a string.

It works like FINDCHR (), but it looks forward from the end of the string.(c) Create a third function,
