In Python, alist of tuplescan be converted into adictionaryby using various methods. Converting a list of tuples into a dictionary can be useful in situations where you have data that is organized as key-value pairs, but it is easier to work with as a dictionary. This conversion can mak...
To create the list of tuples that we will use in this tutorial, run the line of code below in your Python IDE:my_tuples = [("Name", "John"),("Age", 25),("Occupation", "Analyst")]Now we can convert the created my_tuples to a dictionary, which is a mutable object. ...

The alternative method to convert a list into a dictionary is to use the zip() function, which takes two or more iterables and returns a tuple of their corresponding elements. We can use thezip()function to create a list of tuples, where each tuple comprises an index and a value from...
Finally note that the dictionaries are unordered, so the order is undetermined. However if a dictionary d1 occurs before a dictionary d2, all the elements of the first will be placed in the list before the tuples of the latter. But the order of tuples for each individual dictionary is ...
