Hej there,
Loop around your list using the enumerate builtin function and an
appropriate value for start, see
http://docs.python.org/3/library/functions.html#enumerate
thanks! That hint was very helpful, and I rewrote the program as
follows (I learned how to enumerate just yesterday and I figured out
you can do the same with a range(len(list)) ... so here's how I solved
my issue:
That's very poor coding, if you're given a function that does exactly
what you want, why rewrite it and worse still, get it wrong?
PopularCountries = ["Brazil", "China", "France", "India", "Vietnam"]
Year = 2009
Backpackers = 1000000
for Country in range(len(PopularCountries)):
Year += 1
Backpackers = Backpackers*1.15
print("In %d there were %d backpackers worldwide and their most
popular country was %s." % (Year, Backpackers,
PopularCountries[Country]))
In 2010 there were 1150000 backpackers worldwide and their most
popular country was Brazil.
Whoops, what happened to 2009?
In 2011 there were 1322500 backpackers worldwide and their most
popular country was China.
In 2012 there were 1520874 backpackers worldwide and their most
popular country was France.
In 2013 there were 1749006 backpackers worldwide and their most
popular country was India.
In 2014 there were 2011357 backpackers worldwide and their most
popular country was Vietnam.
I will now try to further enhance my program by adding a second list
to the loop.
What do you mean by "enhance", get the output correct or make it even
worse? :)
Again, thank you all!
Raf
So here's the code with enumerate.
PopularCountries = ["Brazil", "China", "France", "India", "Vietnam"]
Backpackers = 1000000
for x, PopularCountry in enumerate(PopularCountries, start=2009):
Backpackers = Backpackers*1.15
print("In %d there were %d backpackers worldwide and their most
popular country was %s." % (x, Backpackers, PopularCountry))
In 2009 there were 1150000 backpackers worldwide and their most popular
country was Brazil.
In 2010 there were 1322500 backpackers worldwide and their most popular
country was China.
In 2011 there were 1520874 backpackers worldwide and their most popular
country was France.
In 2012 there were 1749006 backpackers worldwide and their most popular
country was India.
In 2013 there were 2011357 backpackers worldwide and their most popular
country was Vietnam.
