I want to search countries from my list here is my list:
country=['American Samoa',
'Andorra','Angola','Anguilla'
,'Antarctica',' Barbuda',
'Argentina', 'Armenia', 'Aruba',
'Australia',
'Austria','Azerbaijan’,'Bahamas','Bangladesh','Barbados','BELARUS']
I have used this function but I think it's wrong
def find(f,seq):
for item in country:
if f(item):
return item
Can you please correct my codes Any help would be appreciated
Hm, here's a stab which is perhaps a bit more clear:
def country_found(country_to_find):
countries=['American Samoa','Andorra','Angola','Anguilla','Antarctica',
'Barbuda','Argentina', 'Armenia', 'Aruba','Australia', 'Austria','Azerbaijan’,
'Bahamas','Bangladesh','Barbados','BELARUS']
return (country_to_find in countries)
Then you can just say "if country_found('Armenia'):" or whatever.
"if country_found('Armenia'):" - i'm Armenian :)I think that you can just use
countries = ['American Samoa', ...]
if country in countries:
...
What you need is
filter(f,seq)
That's all.
And if you don't know what is f , it's a pity but we can't guess it.
See also iflter()
And search in the docs with this idea in mind when you need to do something rather generic: "there MUST be some function that does what I want, WHERE is it ?" .
Instead of "HOW to do that ?".
Yet another answer. The logic is basic. If item is in list, it also has an index. And accessing the element with this index (list[index]) will return verily this item :)
def find_country(country):
try:
i = countries.index(country)
res = countries[res]
except:
res = "No such country"
return res
$ python find_country.py
Azerbaijan
Angola
No such country
seqto it if you don't use it? You probably just have to exchangecountryforseq. Also it would be nice to know whatfis doing.
