In this method, the lists are compared without sorting and thus, this method takes into account the order of the data items in the lists. This is a modification of the first method.
Therefore, the first comparison returns not equal. If(len(l1)=len(l2) and len(l1)=sum()):Īs in the above example, for the first comparison, the data items in both the lists are equal but the order of the elements is different. This means that the list is not equal to the list. This method also checks for the order of the elements. For this method, we have to first check if the lengths of both the lists are equal before performing this computation. This method first compares each element of the two lists and store those as summation of 1, which is then compared with the length of the other list. If you have two or more lists of dictionaries and want to combine them into a list of merged dictionaries, where the dictionaries are merged by an attribute. Second comparison Equal Using sum() ,zip() and len() Print("Second comparison",compareList(l3,l4)) Output First comparison Non equal If(collections.Counter(l1)=collections.Counter(l2)): This method also does not take into account the order of the elements of the list. This method tests for the equality of the lists by comparing frequency of each element in first list with the second list. Second comparison Non equal Using collections.Counter()
Print("Second comparison",compareList(l3,l4)) Output First comparison Equal Print("First comparison",compareList(l1,l2)) This means that the list will be equal to the list according to this method of comparison. This checks if the list contains equal data item values but it does not take into account the order of elements in the list. The list.sort() method sorts the two lists and the = operator compares the two lists item by item which means they have equal data items at equal positions. We will discuss certain methods to compare two lists in python. We may at times need to compare data items in the two lists to perform certain operations. So, once we call the function and pass two same dictionaries to it, we will get the following result.The list in python is a collection of similar items. And this function will use the DeepDiff class to compare both dictionaries and return a result based on it. In this example, we have defined a function named compare_dict() which will accept 2 dictionary values. # Calling function to compare dictionaries Print("Both dictionaries are not equal.") # Check if the two dictionaries are equal using deepdiffĭiff = DeepDiff(dict1, dict2, ignore_order=True) So, let us see an example of using the = operator with the dictionary. Moreover, we can use this operator with Python Dictionary as well. The = is a comparison operator in Python that we can use to check if two objects are equal or not in Python. One of the basic ways to compare two strings in Python is by using the = comparison operator in Python. Method 1: Check if two dictionaries are equal in Python using the = operator And we start with the first basic method of using the = operator in Python. Here we will discuss all 4 main methods to check if two dictionaries are equal in Python.
