You can use the Pythoninoperator to check if a string is present in the list or not. There is also anot inoperator to check if a string is not present in the list. l1=['A','B','C','D','A','A','C']# string in the listif'A'inl1:print('A is present in the list')#...
Note: To learn more about concatenating lists, check out the Concatenating Lists section in the tutorial Python’s list Data Type: A Deep Dive With Examples. When it comes to the repetition operator, the idea is to repeat the content of a given sequence a certain number of times. Here are...
We can use the “+” operator in Python to concatenate the lists. Using the “+” operator, you can join two or more lists to form a new list. When you use the “+” operator with lists, a new list is created and the elements of the original lists are copied to the new list in...

Python’s'*' operatorcan be used to easily concatenate two lists in Python. The ‘*’ operator in Python basicallyunpacks the collection of itemsat the index arguments. For example: Consider a list my_list = [1, 2, 3, 4]. The statement*my_listwouldreplace the list with its elements ...
Another solution is to sort the list twice. multi_sort3.py #!/usr/bin/python from typing import NamedTuple from operator import attrgetter def multi_sort(data, specs): for key, reverse in reversed(specs): data.sort(key=attrgetter(key), reverse=reverse) ...
Alternatively, you can use the concatenation operator + to include multiple dictionaries in a list.my_list + [dict1.copy(), dict2.copy()] # Append the copies of dictionaries to the list using concatenation print(my_list) # Print the list # [{'key1': 'value1', 'key2': 'value2'}...
