Lists, strings and tuples are ordered sequences of objects. I've read through the wikis on each and some stack overflow Q&A but km still not getting a solid difference. A tuple is just an object with a combination of values. List Code Snippet: Python is a general-purpose high-level programming language. It's an abstract collection in which you can stuff values. So a tuple is not a list; they have a fixed size. You would use a tuple because it makes sense for your code (you don't want the tuple to change, such as if you were returning multiple values from a function), https://docs.python.org/2.7/library/array.html, https://docs.python.org/3/library/array.html, New comments cannot be posted and votes cannot be cast, More posts from the learnprogramming community. Tuple is one of 4 built-in data types in Python used to store collections of data, the other 3 are List, Set, and Dictionary, all with different qualities and usage.. A tuple is a collection which is ordered and unchangeable..

An array is a more low-level structure and typically quite closely related to the underlying system of memory allocation and de-allocation. ._1zyZUfB30L-DDI98CCLJlQ{border:1px solid transparent;display:block;padding:0 16px;width:100%;border:1px solid var(--newCommunityTheme-body);border-radius:4px;box-sizing:border-box}._1zyZUfB30L-DDI98CCLJlQ:hover{background-color:var(--newCommunityTheme-primaryButtonTintedEighty)}._1zyZUfB30L-DDI98CCLJlQ._2FebEA49ReODemDlwzYHSR,._1zyZUfB30L-DDI98CCLJlQ:active,._1zyZUfB30L-DDI98CCLJlQ:hover{color:var(--newCommunityTheme-bodyText);fill:var(--newCommunityTheme-bodyText)}._1zyZUfB30L-DDI98CCLJlQ._2FebEA49ReODemDlwzYHSR,._1zyZUfB30L-DDI98CCLJlQ:active{background-color:var(--newCommunityTheme-primaryButtonShadedEighty)}._1zyZUfB30L-DDI98CCLJlQ:disabled,._1zyZUfB30L-DDI98CCLJlQ[data-disabled],._1zyZUfB30L-DDI98CCLJlQ[disabled]{background-color:var(--newCommunityTheme-primaryButtonTintedFifty);color:rgba(var(--newCommunityTheme-bodyText),.5);fill:rgba(var(--newCommunityTheme-bodyText),.5);cursor:not-allowed}._1zyZUfB30L-DDI98CCLJlQ:active,._1zyZUfB30L-DDI98CCLJlQ:disabled,._1zyZUfB30L-DDI98CCLJlQ:hover,._1zyZUfB30L-DDI98CCLJlQ[data-disabled],._1zyZUfB30L-DDI98CCLJlQ[disabled]{border:1px solid var(--newCommunityTheme-body)}._1O2i-ToERP3a0i4GSL0QwU,._1uBzAtenMgErKev3G7oXru{display:block;fill:var(--newCommunityTheme-body);height:22px;width:22px}._1O2i-ToERP3a0i4GSL0QwU._2ilDLNSvkCHD3Cs9duy9Q_,._1uBzAtenMgErKev3G7oXru._2ilDLNSvkCHD3Cs9duy9Q_{height:14px;width:14px}._2kBlhw4LJXNnk73IJcwWsT,._1kRJoT0CagEmHsFjl2VT4R{height:24px;padding:0;width:24px}._2kBlhw4LJXNnk73IJcwWsT._2ilDLNSvkCHD3Cs9duy9Q_,._1kRJoT0CagEmHsFjl2VT4R._2ilDLNSvkCHD3Cs9duy9Q_{height:14px;width:14px}._3VgTjAJVNNV7jzlnwY-OFY{font-size:14px;line-height:32px;padding:0 16px}._3VgTjAJVNNV7jzlnwY-OFY,._3VgTjAJVNNV7jzlnwY-OFY._2ilDLNSvkCHD3Cs9duy9Q_{font-weight:700;letter-spacing:.5px;text-transform:uppercase}._3VgTjAJVNNV7jzlnwY-OFY._2ilDLNSvkCHD3Cs9duy9Q_{font-size:12px;line-height:24px;padding:4px 9px 2px;width:100%}._2QmHYFeMADTpuXJtd36LQs{font-size:14px;line-height:32px;padding:0 16px}._2QmHYFeMADTpuXJtd36LQs,._2QmHYFeMADTpuXJtd36LQs._2ilDLNSvkCHD3Cs9duy9Q_{font-weight:700;letter-spacing:.5px;text-transform:uppercase}._2QmHYFeMADTpuXJtd36LQs._2ilDLNSvkCHD3Cs9duy9Q_{font-size:12px;line-height:24px;padding:4px 9px 2px;width:100%}._2QmHYFeMADTpuXJtd36LQs:hover ._31L3r0EWsU0weoMZvEJcUA{display:none}._2QmHYFeMADTpuXJtd36LQs ._31L3r0EWsU0weoMZvEJcUA,._2QmHYFeMADTpuXJtd36LQs:hover ._11Zy7Yp4S1ZArNqhUQ0jZW{display:block}._2QmHYFeMADTpuXJtd36LQs ._11Zy7Yp4S1ZArNqhUQ0jZW{display:none}._2CLbCoThTVSANDpeJGlI6a{width:100%}._2CLbCoThTVSANDpeJGlI6a:hover ._31L3r0EWsU0weoMZvEJcUA{display:none}._2CLbCoThTVSANDpeJGlI6a ._31L3r0EWsU0weoMZvEJcUA,._2CLbCoThTVSANDpeJGlI6a:hover ._11Zy7Yp4S1ZArNqhUQ0jZW{display:block}._2CLbCoThTVSANDpeJGlI6a ._11Zy7Yp4S1ZArNqhUQ0jZW{display:none} Individual element of List data can be accessed using indexing & can be manipulated. Note also the length of tuple must match. Tuples are used to store multiple items in a single variable. It will be helpful in use cases where we want to leverage the power of NumPy operations on existing data structures. That means, you cannot have tuples (3,4) and (3.1, 4)because the first is of type “int*int” and the second is “float*int”. Tuples are immutable so, It doesn't require extra space to store new objects. .Rd5g7JmL4Fdk-aZi1-U_V{transition:all .1s linear 0s}._2TMXtA984ePtHXMkOpHNQm{font-size:16px;font-weight:500;line-height:20px;margin-bottom:4px}.CneW1mCG4WJXxJbZl5tzH{border-top:1px solid var(--newRedditTheme-line);margin-top:16px;padding-top:16px}._11ARF4IQO4h3HeKPpPg0xb{transition:all .1s linear 0s;display:none;fill:var(--newCommunityTheme-button);height:16px;width:16px;vertical-align:middle;margin-bottom:2px;margin-left:4px;cursor:pointer}._1I3N-uBrbZH-ywcmCnwv_B:hover ._11ARF4IQO4h3HeKPpPg0xb{display:inline-block}._2IvhQwkgv_7K0Q3R0695Cs{border-radius:4px;border:1px solid var(--newCommunityTheme-line)}._2IvhQwkgv_7K0Q3R0695Cs:focus{outline:none}._1I3N-uBrbZH-ywcmCnwv_B{transition:all .1s linear 0s;border-radius:4px;border:1px solid var(--newCommunityTheme-line)}._1I3N-uBrbZH-ywcmCnwv_B:focus{outline:none}._1I3N-uBrbZH-ywcmCnwv_B.IeceazVNz_gGZfKXub0ak,._1I3N-uBrbZH-ywcmCnwv_B:hover{border:1px solid var(--newCommunityTheme-button)}._35hmSCjPO8OEezK36eUXpk._35hmSCjPO8OEezK36eUXpk._35hmSCjPO8OEezK36eUXpk{margin-top:25px;left:-9px}._3aEIeAgUy9VfJyRPljMNJP._3aEIeAgUy9VfJyRPljMNJP._3aEIeAgUy9VfJyRPljMNJP,._3aEIeAgUy9VfJyRPljMNJP._3aEIeAgUy9VfJyRPljMNJP._3aEIeAgUy9VfJyRPljMNJP:focus-within,._3aEIeAgUy9VfJyRPljMNJP._3aEIeAgUy9VfJyRPljMNJP._3aEIeAgUy9VfJyRPljMNJP:hover{transition:all .1s linear 0s;border:none;padding:8px 8px 0}._25yWxLGH4C6j26OKFx8kD5{display:inline}._2YsVWIEj0doZMxreeY6iDG{font-size:12px;font-weight:400;line-height:16px;color:var(--newCommunityTheme-metaText);display:-ms-flexbox;display:flex;padding:4px 6px}._1hFCAcL4_gkyWN0KM96zgg{color:var(--newCommunityTheme-button);margin-right:8px;margin-left:auto;color:var(--newCommunityTheme-errorText)}._1hFCAcL4_gkyWN0KM96zgg,._1dF0IdghIrnqkJiUxfswxd{font-size:12px;font-weight:700;line-height:16px;cursor:pointer;-ms-flex-item-align:end;align-self:flex-end;-webkit-user-select:none;-ms-user-select:none;user-select:none}._1dF0IdghIrnqkJiUxfswxd{color:var(--newCommunityTheme-button)}._3VGrhUu842I3acqBMCoSAq{font-weight:700;color:#ff4500;text-transform:uppercase;margin-right:4px}._3VGrhUu842I3acqBMCoSAq,.edyFgPHILhf5OLH2vk-tk{font-size:12px;line-height:16px}.edyFgPHILhf5OLH2vk-tk{font-weight:400;-ms-flex-preferred-size:100%;flex-basis:100%;margin-bottom:4px;color:var(--newCommunityTheme-metaText)}._19lMIGqzfTPVY3ssqTiZSX._19lMIGqzfTPVY3ssqTiZSX._19lMIGqzfTPVY3ssqTiZSX{margin-top:6px}._19lMIGqzfTPVY3ssqTiZSX._19lMIGqzfTPVY3ssqTiZSX._19lMIGqzfTPVY3ssqTiZSX._3MAHaXXXXi9Xrmc_oMPTdP{margin-top:4px} There are several different kinds of list implementation you can try using, but the two most common ones are an array list and a linked list. Press question mark to learn the rest of the keyboard shortcuts. dynamic arrays (vectors, arraylist, etc) can be efficiently resized, and are the preferred data structure for lists unless you have a reason not to use them. The ValueTuple types are mutable, whereas Tuple are read-only. Python programs are easy to test and debug. Python — List vs Tuple vs Dictionary. It's a feature you have to use responsibly, but if you do, it can help make your code much less verbose. The name itself doesn't say how they are implemented and if they except values of different types or not. A "Person" class with a name and an age can be considered a 'tuple' of String and Number for example.
