Using python to match the values in a dictionary's array with an original value

I have the following in a dictionary:

"key": ["array_value1", "array_value2", "array_value3"],

I have another value I'd like to check against one of the values in the array in an if-else statement. For example:

if checkedValue == array_value1:
    #something happens

I don't know how to iterative over the values in "key" so that it automatically checks for the values inside it.

Dictionary values have a type, just like anything else. It looks like your dictionary value in this case is an array, so iterate over it in the same way as you iterate over any other iterable collection:

for val in mydict["key"]:
    if checkedValue == val:
        doSomething

As pointed out in nickflees's answer, the array type works well with the in keyword, but this is just syntactic sugar for iterating through the array until you find the desired value. The point is that dictionary values are not "special" types in any way; mydict["key"] is just a reference to whatever you've stored under that key in the dictionary.

Another way using any.

for k, v in dy.iteritems():
    if any(val == checkValue for val in v):
        print "something happens"

For Python 3, use items instead of iteritems.

You could do something like

if checkedValue in dict_name['key']:
    #do something
