I just have one question if in one of my dictionary i have more value than the other can i still compare both dictionary or i have to change my code ? For example like this:

My code:

for key in result:
     if result[key]!=result2[key]:
            print("%s not equal"% (key))

output:

result={"jazi": 1, "juge": 1, "juha": 9, "lebe": 4}
result2={"jazi": 3, "juge": 4, "juha": 1, "lebe": 4, "aba":7, "meze":9}

Using get() as the others have suggested is the simplest solution, but if you wanted you could be more specific than just saying "not equal":

result={"jazi": 1, "juge": 1, "juha": 9, "lebe": 4}
result2={"jazi": 3, "juge": 4, "juha": 1, "lebe": 4, "aba":7, "meze":9}

print("Only in result:", ", ".join(set(result).difference(result2)))
print("Only in result2:", ", ".join(set(result2).difference(result)))

for key in set(result).intersection(result2):
     if result[key]!=result2[key]:
            print("%s not equal"% (key))

Gives:

Only in result: 
Only in result2: aba, meze
juha not equal
jazi not equal
juge not equal

Or possibly a bit clearer:

keys, keys2 = set(result), set(result2)
print("Only in result:", ", ".join(keys - keys2))
print("Only in result2:", ", ".join(keys2 - keys))

for key in keys & keys2:
     if result[key]!=result2[key]:
            print("%s not equal"% (key))

which is exactly the same but pre-computes the sets so you can use inline operators - for .difference() and & for .intersection().

Or if you do just want the 'not equal' message:

keys, keys2 = set(result), set(result2)

for key in (keys ^ keys2) | {
        key for key in keys & keys2 if result[key] != result2[key] }:
    print("%s not equal"% (key))

How to compare dictionaries in Python, Comparing two dictionaries checks each corresponding key-value pair between the two dictionaries for equality. For example Use a for loop to check for equal pairs in two dictionaries You can read more about list comprehensions here. By nature, a dictionary is a one-to-one mapping, but it’s not hard to make it one-to-many—in other words, to make one key map to multiple values. There are two possible approaches, depending on how you want to treat duplications in the set of values for a key. The following approach allows such duplications:


This is one approach using dict.get

Ex:

result={"jazi": 1, "juge": 1, "juha": 9, "lebe": 4}
result2={"jazi": 3, "juge": 4, "juha": 1, "lebe": 4, "aba":7, "meze":9}

for key, value in result.items():
    if value != result2.get(key, 0):  #You can add additional condition to check if key present in `result2`
        print("%s not equal"% (key))

Output:

jazi not equal
juge not equal
juha not equal

Compare Two Dictionaries, Make Two Dictionaries. importers Find the difference between importers and exporters importers.keys() Find Key, Values Pairs In Common. Basically A dictionary is a mapping between a set of keys and values. The keys support the basic operations like unions, intersections, and differences. When we call the items() method on a dictionary then it simply returns the (key, value) pair. Now, Consider two dictionaries:


Yes you can but do not use dict['key'] and use dict.get('key'). Below is the code which won't give you an error for any number of keys.

for key in result:
    if result.get(key, "")!= result2.get(key, ""):
        print("%s not equal"% (key))

How to compare two dictionaries in C#?, To compare two dictionaries, firstly set the two dictionaries −Dictionary OneIDictionary d Add(4,88); // Dictionary One elements Console. Count) { // Require equal count. equal = true; foreach (var pair in d) { int value; if (d2. In this article you can see how to compare two dictionaries in python: * if their keys match * the difference in the keys * the difference in the values The first check is to verify that two dictionaries have equal keys.


If you do not have nested dicts, the set() approach could bring something (see the docs for more info)

result={"jazi": 1, "juge": 1, "juha": 9, "lebe": 4}
result2={"jazi": 3, "juge": 4, "juha": 1, "lebe": 4, "aba":7, "meze":9}

set_1 = set((k, v) for k, v in result.items())
set_2 = set((k, v) for k, v in result2.items())

print(f"not equals: {sorted(list(set1 ^ set2))}")
# not equals: [('aba', 7), ('jazi', 1), ('jazi', 3), ('juge', 1), ('juge', 4), ('juha', 1), ('juha', 9), ('meze', 9)]
print(f"only in first: {sorted(list(set_1 - set_2))}")
# only in first: [('jazi', 1), ('juge', 1), ('juha', 9)]
print(f"only in second: {sorted(list(set_2 - set_1))}")
# only in second: [('aba', 7), ('jazi', 3), ('juge', 4), ('juha', 1), ('meze', 9)]


How to compare two different dictionary values in Python, You compare dictionary values by accessing the dictionary with the appropria Can a dictionary have multiple values python? We have two dictionary:. Let’s discuss a simple yet useful utility of conversion of two lists into a key:value pair dictionary. Method #1 : Naive Method The basic method that can be applied to perform this task is the brute force method to achieve this.


Your both dictionaries can have different keys too. So you need to iterate on the combination of keys present in both dictionaries. For that you may use set to get uniques list of keys from both dictionaries as:

>>> dict1 = {'a': 1, 'b': 2, 'd': 4}
>>> dict2 = {'a': 3, 'c': 3, 'd': 4}

>>> my_keys = set(dict1.keys() + dict2.keys()) # To get unique keys from both dicts

>>> my_keys
set(['a', 'c', 'b', 'd'])

Now, in order to get item from dict, use dict.get(key) instead of dict[key]. dict[key] raises KeyError exception if the key is not found in the dictionary. Whereas dict.get(get) returns None.

Hence your code to iterate the dictionary should be like:

for key in my_keys:
    if dict1.get(key) != dict2.get(key):
        print("{} is having different value".format(key))

# which will print:
#     a is having different value
#     c is having different value
#     b is having different value

Note: Since dict.get returns None if the key is not found, above code won't return correct result if some key is not present in one dict, and same key is present in other dict with value as None. In that case, you should use dict.get with default value as dict.get(key, default_value) (where default_value should be value/string which will never be present as value in your dict)

Python, Handling missing keys in Python dictionaries � Python - Concatenate values with same keys in a list of dictionaries � Python | Set Difference in list� Compare Not_Equal is more efficient than comparing Equal. As such two dicts are not equal if any key values in one dict is not found in the other dict. The code below takes into consideration that you maybe comparing default dict and thus uses get instead of getitem [].


Python Dictionary(Dict): Update, Cmp, Len, Sort, Copy, Items, str , Python Dictionary is classified into two elements: Keys and Values. More than one entry per key is not allowed ( no duplicate key is allowed) The compare method cmp() is used in Python to compare values and keys of� Here’s one way: Dictionary = {(4, 5): (2.733), (5, 2): (2.4533), (6, 2): (4.533), (7, 3): (1.333)} dictList=zip(Dictionary.values(),Dictionary.keys()) dictList.sort


Proper way to compare two Dictionaries, A 32-bit hash returned by GetHashCode has 2^32 possible values, with a probability distribution dependent on the hashing function. If there are more than 2^32� It is possible to compare two Dictionary instances for equality using a custom method with key-value pair checking. There are other possible implementations, but this one is fairly resource-efficient and also simple. Tip: When testing this method, make sure to change keys and values in both dictionaries.


How to compare two dictionaries? - Academy, Both contain Name and Value pairs. I have to compare both the dictionaries Can anyone help how do we compare dictionaries ? kkpatel June 16, 2020, 11 :35am #1. Hi All Fur more custom cases LINQ can often help to adress specifics. Compare Two Columns and Pull the Matching Data. If you have two datasets and you want to compare items in one list to the other and fetch the matching data point, you need to use the lookup formulas. Example: Pull the Matching Data (Exact) For example, in the below list, I want to fetch the market valuation value for column 2.
