The loop will not perform any code below the unindented line. WebPython Desktop Apps with Tkinter; Tkinter Message box. Once they have completed the above task, you can think with them about other modifications that can be made, such as changing the minimum and maximum of the numbers that can be produced or deciding to only roll again if the number is less than or equal to five. Because indexing begins with 0, the highest number that we can index is always the length of the list minus 1. defining an index which takes a random number with these minimum and maximum values (line 3), storing the adjective at this index as the variable to be used (line 4). We create variables here so as to simplify the rest of the code. Parameters go in parentheses. Could you clarify please. But opting out of some of these cookies may affect your browsing experience.
