I am trying to loop through a dictionary and return the values and corresponding index of the value. So far, I am able to return the entire list.

cdict = {'ZS': [3,3,3,5,5,5,5,7,7,7,7,8,8,11,11,11,11,11,11,1,1,1,1,3]}

for k, v in cdict.items():
    print (v)

I would like to be able to return the following: 3, 0 3, 1 3, 2 5, 3 ... 3, 23. Where 0,1,2,3 etc (in the second column) are the respective index positions of the values. Any help is greatly appreciated.

You've already shown that you can iterate over the dictionary. So what's left is to print the list with indexes. Python has a nice function for that called enumerate:

for (i, v) in enumerate([3,3,5]):
    print(v, i)

3 0
3 1
5 2

Enumerate turns any iteratable into pairs of index and value. So it doesn't just work for list but anything you can iterate.

python 3.x, I am trying to loop through a dictionary and return the values and corresponding index of the value. So far, I am able to return the entire list. Then you iterated through the dictionary in sorted order by using sorted (). The key function ( by_value ()) tells sorted () to sort incomes.items () by the second element of each item, that is, by the value ( item [1] ). You may also just want to iterate through the values of a dictionary in sorted order,

cdict = {'ZS': [3,3,3,5,5,5,5,7,7,7,7,8,8,11,11,11,11,11,11,1,1,1,1,3]}

for k, v in cdict.items():
    for idx in range(len(v)):
        print('{}, {}'.format(v[idx], idx))

How to Iterate Through a Dictionary in Python – Real Python, In this step-by-step tutorial, you'll take a deep dive into how to iterate through that support element access using integer indices, dictionaries are indexed by keys. In Python 3.6 and beyond, the keys and values of a dictionary are If you use a list comprehension to iterate through the dictionary's values,  In this tutorial, learn how to loop through dictionary elements in Python. To loop or iterate over each element of a dictionary variable, you have to use the for loop of Python. You can get the dictionary variable keys and values in the output. Use the for loop of the Python and use only keys or values in your programming.

Single-line solution:

a = list(map(lambda v: list(map(lambda x: print("{}, {}".format(*x[::-1])) or x[::-1], enumerate(v))), cdict.values()))

bonus: in a you could find the following list: [[(3, 0), (3, 1), (3, 2), (5, 3), (5, 4), (5, 5), (5, 6), (7, 7), (7, 8), (7, 9), (7, 10), (8, 11), (8, 12), (11, 13), (11, 14), (11, 15), (11, 16), (11, 17), (11, 18), (1, 19), (1, 20), (1, 21), (1, 22), (3, 23)]]

Different ways to Iterate / Loop over a Dictionary in Python , Iterate over key value pairs of dictionary using dict.items() Python: Find duplicates in a list with frequency count & index positions · How to  vba collection Looping through a Scripting.Dictionary using index/item number. vba iterate through dictionary values (3) According to the documentation of the Item property: Sets or returns an item for a specified key in a Dictionary object.

Not sure if this is what your after but this will print the item in the dict and the index:

cdict = {'ZS': [3,3,3,5,5,5,5,7,7,7,7,8,8,11,11,11,11,11,11,1,1,1,1,3]}
index = -1
for e in cdict['ZS']:
    index += 1
    print("Index:",index, "item", e)

Python 3 Notes: More on for Loops, dictionaries. The most prototypical use of for in loop is over a list. The .​items() method on a dictionary induces a pseudo-list of (key, value) tuples. The for First, range() together with len('penguin') produces a list of indexes for the word: >  python iterate over list values for key a list which is the value of a key in a dictionary? i.e. loop through each key, exaust all values in the lists and

Python, Using list comprehension. # Iterating through value lists dictionary. res = [[i for i in test_dict[x]] for x in test_dict.keys()]. # printing result. print ( "The list values of  I want to iterate through a dictionary in python by index number. Example : dict = {'apple':'red','mango':'green','orange':'orange'} I want to iterate through the dictionary from first to last, so that I can access the dictionary items by their indexes. For example, the 1st item will be apple, and the 2nd item will be mango and value will be green.

Iterate over a dictionary in Python, Dictionary in Python is an unordered collection of data values, used to store data values like a map, which unlike other Data Python3 code to iterate through all keys in a dictionary List Of given states: Rajasthan Bihar Maharashtra Gujarat. You can also enumerate through the dictionary and can get the index of each of the key. In the final output you can see the index for each of the key . Just remember d.keys(), d.values() returns a dict_keys object which behaves a lot more like a set than a list. Therefore, dict.values() needs to be wrapped in a list.

Dictionaries - PY4E, In a list, the index positions have to be integers; in a dictionary, the indices can be as a mapping between a set of indices (which are called keys) and a set of values. Then you could traverse the string and, for each character, increment the  Dictionary < TKey, TValue > Class. The Dictionary < TKey, TValue > class is a generic class and you can store any Data Types. The C# Dictionary Add method takes two parameters, which mapping from a set of keys to a set of values.
