Dictionary to list of tuple conversion in Python Python Server Side Programming Programming ging the collection type from one type to another is a very frequent need in python. Can't we have either lists ortuple… List: Lists are just like dynamic sized arrays, declared in other languages (vector in C++ and ArrayList in Java). Lists are modifiable (or 'mutable', as a programmer may say), so their values can be changed. And if there is no difference between the two, why should we have the two? It’s a comma separated Key Value pairs. A tuple i s a sequence of values much like a list. You may have spaces after the commas if you feel it necessary - it doesn't really matter. Add to PDF Junior . Lists and tuples are standard Python data types that store values in a sequence. So thats all for this Python Tuple vs List. Removing that sorry cat is an easy task, thankfully, so you have to wallow in sadness for as short a time as possible: You've just removed the 2nd cat in your list - poor old Snappy. Where lists come into their own is how they can be modified. The elements in a list can be changed. To get an even deeper look into lists, read our article on Python Lists. If the user wants to utilize the sequence as a dictionary key, a tuple is a better choice because dictionary keys are immutable. These data types are all different from each other and thus important to know which data-type to use for your code in order to improve the quality and efficiency of your code.
