Question

I get “TypeError: iterable argument required” when i try to execute the code below:

for i in range(len(SE_FE_Lists)):                    
    print "** ", SE_FE_Lists[i]["List_contents"]
    if ":" in SE_FE_Lists[i]["List_contents"]:
        print ": ", SE_FE_Lists[i]
        print "*--* ", SE_FE_Lists[i]["List_contents"]
    if " " in SE_FE_Lists[i]["List_contents"]:
        print "Space :", SE_FE_Lists[i]
        print "*--* ", SE_FE_Lists[i]["List_contents"]    

The error is located in the line if “:” in List[i][“List_contents”]:

The contents of the list :

[{'List_selection': 'List1', 'List_contents': '1:4'}, {'List_selection': 'List2', 'List_contents': '1 2 4'}, {'List_selection': 'List3',
 'List_contents': 1}]

As output i get :

**  1:4

:  {'List_selection': 'List1', 'List_contents': '1:4'}

*--*  1:4

**  1 2 4

Space : {'List_selection': 'List2', 'List_contents': '1 2 4'}

*--*  1 2 4

**  1

Thanks.

First, if you want to iterate over items of your object List, you should use the pythonic way of doing it :

for item in List:

    if ":" in item["List_contents"]:
        print "*--* ", item["List_contents"]
    if " " in item["List_contents"]:
        print "*--* ", item["List_contents"]  

for the error you encounter, it looks like your List object is not a dictionnary list.

EDIT :

after your edition, the problem is due to the last item of your List : {'List_selection': 'List3', 'List_contents': 1}, here the member ‘List_contents’ is an integer, and python can’t find “:” in an integer…
If you can’t modify the content of the list, try to force python to use a string with the str() method :

if ":" in str(item["List_contents"]):
