merged_dict = ChainMap(dict1, dict2, dict3) 6. Merge Dictionaries using for Loop When using afor loopto merge dictionaries, you caniterate over the dictionariesand add the key-value pairs to a new dictionary, allowing you to combine multiple dictionaries into a single dictionary. It allows ...
Write a Python program to interleave two lists into another list randomly. Use the map() function. Sample Solution: Python Code: # Import the 'random' moduleimportrandom# Define a function named 'randomly_interleave' that takes two lists as inputdefrandomly_interleave(nums1,nums2):# Create a...
Thezip()function in Python is used to combine two lists into a single list of tuples, where the first element of the tuple contains the elements of first list, the second element of the tuple contains the element from second list and pass this as an input to dict() constructor to creat...
Lists and Dictionaries:To combine a list with a dictionary, you might want to extract the dictionary’s keys or values and then concatenate them with the list. This can be useful when you need to merge data from different sources or formats. Here’s an example of how you can do this: ...
In the instance above, thezip()function is used to combine the keys and values lists into a list of key-value pairs. The output list of key-value pairs is then passed to thedict()function to create a dictionary. Finally, the resulting dictionary is printed to the console. ...
Example:We have different sales data stored in separate lists in Python, and we want to combine them into a single list to analyze the overall sales through Python. west_coast_sales = [35000, 42000, 38000, 41000] midwest_sales = [28000, 32000, 29000, 31000] ...

print(result_list) In the given example, we have two lists –“L1” contains the numerical values [1, 2, 3] and “L2” contains the alphabetic characters [“x”, “y”, “z”]. Using the itertools.chain() function, we concatenate these lists into a single iterable, represented by “...
