2. Submit a Python file that includes a single line of code that prints 25 '*' characters followed by 25'+" characters, with no space in between. It must, of course, use the print function. The two characters must appear in your code much less than 25 times - at most three each! 3. Write a program that assigns the value 4 to the variable x, the value 2 to the variable y and then uses exactly three print function calls to generate the output below (four lines, with the second line blank). The print calls must use the variables x and y rather than the values 4 and 2. The trick is to change the assignment of the sep and end parameters in the call to print . The character 4 is the first character on the 1st, 3rd and 4th lines of output. 4 2 4,2 42
