You can't give execute permission to a file that isn't a program because the shell can't interpret its contents. Trying to run this type of file results in an error.

Write a program that prints the following patterns separately, one below the other each pattern separated from the next by one blank line. Use for loops to generate the patterns. All aster- isks (*) should be printed by a single statement of the form print '*', (which causes the asterisks to print side by side separated by a space). (Hint: The last two pat- terns require that each line begin
with an appropriate number of blanks.) Extra credit: Combine your code from the four separate problems into a single program that prints all four patterns side by side by making clever use of nested for loops. For all parts of this program—minimize the numbers of asterisks and spaces and the number of statements that print these characters.
