bookFormatting with Ordering

In the previous chapter, we created a string-pattern, and then inserted variables within it. We did it in order. Another way to create a pattern string - is to predefine the order of inserting.

To do it, we need to specify index of element that should be inserted there. It's a bit obvious, but needs to be clarified: indexation in Python starts with 0, and all the indices within {} blocks must be consecutive (like, {1} {0} {2}, but not {3} {0} {1} as there is no 2). For example,


              
12

            
pattern = "{1} manipulation in {0}"
print(pattern.format('Python', 'String'))
copy

Note, unless 'Python' was written in the first place it was inserted within the last block (as 'Python' is the first element, and has index 0). The same logic applies to 'string'.

Task

Create string holiday with text Independence Day in country is celebrated on the day of month. The order of inserting within .format() function is the next: day, month, and country. According to this, format your string following the order.
