In Python, list comprehension is a concise way to create a newlistbased on the values of an existing list. List comprehension is often used for its brevity and readability compared to traditionalfor-loop. This Python tutorial discusses what is list comprehension, and its syntax with easy-to-un...
We can see that 10,20 and 90 are the elements that are common in both lists. So they were removed. 3. Using List Comprehension to Remove Elements in Python With List comprehension, we will iterate the first list using the for loop and check if the iterated element is present in the se...
List Concatenation can also be done using the list comprehension technique. In this case, a new list is created, this method is a one-liner alternative to the loop method. list1 = [1, 4, 5, 6, 5] list2 = [3, 5, 7, 2, 5] # using list comprehension to concatenate result = [...
It describes various ways to join/concatenate/add lists in Python. For example – simply appending elements of one list to the tail of the other in a for loop, or using +/* operators, list comprehension, extend(), and itertools.chain() methods. Contents Python Add Lists – 6 Ways to...
You can use theenumerate()function to add a counter to an iterable object, such as a list, and return an enumerate object. This object contains pairs of the form(index, element)for each element in the iterable. We can use this function in combination with a loop to create or convert a...
# Example dictionaries to compare dict1 = {'a': 1, 'b': 2, 'c': 3} dict2 = {'a': 1, 'b': 2, 'c': 4} # Comparing dictionaries using a loop def compare_dictionaries(dict1, dict2): if len(dict1) != len(dict2): return False for key in dict1: if key not in dict...
Using nested list comprehension Using numpy module Approach 1: nested loops For this approach, we will use nested loops which are simply a loop within a loop, to multiply the matrices and store them in a resultant matrix. We will use three loops, the first loop will be for iterating throu...
The list comprehension iterates through dict1.keys() using a for loop, checking if each key is not present in dict2. If the condition is true, the key is appended to keys_in_dict1_only. A similar list comprehension is used to find keys unique to dict2. ...

The newlist variable is printed in the last line of the program using the codeprint('Concatenated List: ',newlist). 5) Using Native Function To concatenate two lists, we will first traverse the second list using a for loop. We will keep appending the elements of this list to the first...
