How to print dictionary by key when some keys have multiple values

Related searches

I have a large dictionary and am only trying to print the keys that have multiple values. For each value, I would like to print on a new line.

I tried iterating through the dictionary, but I'm not sure how to go through the individual values when you get to a certain key.

for i, n in errorDict.items():
    if len(errorDict[i]) > 1:
        print (i)
        n=0
        while n < len(errorDict[i]):
            print (errorDict[i](n))
            n += 1

I would like the end result to look like this.

Model1
ErrorCode1
ErrorCode2
ErrorCode3

Model2
ErrorCode1
ErrorCode2

Model3
ErrorCode1
ErrorCode2
ErrorCode3
ErrorCode4
ErrorCode5

You can simplify/correct your code to this:

for key, values in errorDict.items():
  if len(values) > 1:
    print(key)
    for v in values:
      print(v)

Printing dictionary keys based on multiple value conditions, Closed last year. I have a dictionary with two values for each key, that looks like this for example: my_dict =� For printing the keys and values, we can either iterate through the dictionary one by one and print all key-value pairs or we can print all keys or values at one go. For this tutorial, we are using python 3. Print all key-value pairs using a loop : This is the simplest way to print all key-value pairs of a dictionary. Using one for loop, we will iterate through each element of the dictionary* one by one* and then print them out. The code will look like as below :

for i, n in errorDict.items():
    if len(n) > 1:
        print (i)
        for val in n:
            print(val)

In the Python dictionary, can 1 key hold more than 1 value?, How can I append all dictionaries (from a list of dict) with the value 'A' in the key create a dictionary with duplicate keys then the last instance of that key: value will type for that value, you should be able to save multiple values for a single key. the value to contain more than one piece of information, you can put in some� If you pass a dictionary (or other mapping with support for the .items () method) to this function: rdict = revdict_buckets (some_dict) then you’ll get back a dictionary of lists. Those results will be keyed on values (from some_dict) and each entry will have a list of of keys (from some_dict) which held that value.

for item in errorDict.keys():
    if len(errorDict.get(item)) > 1:
        print(item)
        for item2 in dict.get(item):
            print(item2)    

You need to use the keys() method to get the keys and then iterate over it to get the item corresponding to the key and check for your necessary condition.

Associating Multiple Values with Each Key in a Dictionary, Problem. You need a dictionary that maps each key to multiple values. A normal dictionary performs a simple mapping of a key to a value. This recipe shows def get_values_if_any(d, key): return d.get(key, {}).keys( ) For that purpose, you need to make some of the design decisions that the recipe highlights. Do you� list_of_values = d1[key] Here’s how to remove one value for a key, if you don’t mind leaving empty lists as items of d1 when the last value for a key is removed: d1[key].remove(value) Despite the empty lists, it’s still easy to test for the existence of a key with at least one value: def has_key_with_some_values(d, key): return d.has_key

Dictionaries — How to Think Like a Computer Scientist: Learning , They map keys, which can be any immutable type, to values, which can be any type We can print the current value of the dictionary in the usual way: Another way to create a dictionary is to provide a list of key:value pairs using the A view object has some similarities to the range object we saw earlier — it is a lazy� dict.items() returns an iterable view object of the dictionary that we can use to iterate over the contents of the dictionary, i.e. key-value pairs in the dictionary and print them line by line i.e. # Iterate over key/value pairs in dict and print them for key, value in student_score.items(): print(key, ' : ', value)

Python, A dictionary in Python consists of a collection of key-value pairs. we make a set which contains keys that use to compare and using comparison print (s1. issubset(sports.keys())) @geeksforgeeks , Some rights reserved.

We have a lot of variations and applications of dictionary container in Python and sometimes, we wish to perform a filter of keys in dictionary, i.e extracting just the keys which are present in particular container.
