How To Iterate Through Dict Values Containing Lists And Remove Items?

Python novice here. I have a dictionary of lists, like so: d = { 1: ['foo', 'foo(1)', 'bar', 'bar(1)'], 2: ['foobaz', 'foobaz(1)', 'apple', 'apple(1)'], 3: ['oz', 'oz(1)', 'b

Solution 1:

You can re-build the dictionary, letting only elements without parenthesis through:

d = {k:[elem for elem in v if not elem.endswith(')')] for k,v in d.iteritems()}

Solution 2:

temp_dict = d
forkey, value is temp_dict:
    for elem in value:
        if temp_dict[key][elem].find(")")!=-1:
            d[key].remove[elem]

you can't edit a list while iterating over it, so you create a copy of your list as temp_list and if you find parenthesis tail in it, you delete corresponding element from your original list.

Solution 3:

Alternatively, you can do it without rebuilding the dictionary, which may be preferable if it's huge...

for k, v in d.iteritems():
   d[k] = filter(lambda x: not x.endswith(')'), v)
