Extend the list by appending all the items in the given list; equivalent to a[len(a):] = L. 将所有元素追加到已知list来扩充。 --- 官方文档描述 extend 对象是iterable >>> lst ['java', 'python', 'go', 'c++', 'c'] >>> lst.extend(0) Traceback (most recent call last): File "...
We can append/add a dictionary to the list using thelist.append()method of Python. We know that Python lists are mutable and allow different types of data types as their values. Since it is mutable, we can add elements to the list or delete elements from the list. Advertisements In this...
In the above example, to accessbluein the updated color list, we can type“print (color[1])”whereas if we want to accesspurple, we need to issue the“print (color[3][0])”command. Time Complexity The time complexity is O(1) which means that the List Append method has a constant ...

The reason is that the extend() method works in place, which means it modifies the object directly. On the other hand, the object remains the same when the concatenation operator is used. You should explicitly assign the operation to the object back, like my_list += ["It", "is", "...
model_name = relation._meta.object_name# Try to look up the related model, and if it's already loaded resolve the# string right away. If get_registered_model raises a LookupError, it means# that the related model isn't loaded yet, so we need to pend the relation# until the class is...
