drawback in python

Here are the major drawbacks&news_url=https://content.techgig.com/is-python-losing-its-charm-here-are-the-major-drawbacks/articleshow/78130196.cms&tags=Technology&ppuserinfo=. If you try to explicitly call each base class initializer (e.g. I know there is threading support, but compared to Java or C, the GIL will really lower your performance. Can be tricky when you don't know why a locked resource wasn't released ( my experience about that was mod_python in freeswitch ). The pyramid is a high-speed python web framework and it is open source. Lets look into the Final thoughts. However, the main Sun/Oracle JVM is extensively documented wrt GC behavior and configurability, to the extent that there are whole books published on JVM tuning. I have colleagues that have burned a quarter million core-hours just getting Python (with numpy, mpi4py, petsc4py, and other extension modules) loaded on 65k cores. This is also true of many other high level languages, but Python tends to abstract away most hardware details. @ncoghlan - to me the great things about Python are elegance of syntax and succintness - expressiveness. That it is not the built-in language of web browsers, instead of JavaScript. Those hard to find bugs that resulted from a hard to spot typo were amazingly enough first made in the 1950s. This allows us to improve and customize your browsing experience. It's usually the result of some subtle bugs. The syntax in Python helps the programmers to do coding in fewer steps as compared to Java or C++. rev 2020.12.18.38240, The best answers are voted up and rise to the top. VIF has decreased. When you work interactively, every expression and statement you type in is evaluated and executed immediately: >>> >>> The main drawback of python for me, compared to NodeJS is the whole sharing projects onto different machines with virtualenv or whatever. ). Check out this article to see 10 exciting advantages of Python. Notice that the types are still implicit (but let variables are for all intents and purposes statically typed since they cannot be rebound to a new value, while var variables may still be dynamically typed). I don't see what the big deal about explicit self is. The GIL prevents the use of threading to speed up code, (although this is usually a premature optimization). The major drawback of reverse cipher is that it is very weak. You would seriously edit C or Java code to change the block level of some code without changing its indentation? 2) Implementation details (GIL, performance) can you give an example? I listed the advantages because I think they outweigh the cons. Python is a powerful programming language for mobile and web development projects. Chaotic docs (compare with Perl5 documentation, which is superb). Nested functions kind of suck in that you can't modify variables in the outer scope. Of these complaints, it's only the very first one that I care enough about that I think it should be added to the language. That is quite useful, but a drawback of Waxeye is that it only generates a AST. Python seems all the rage these days, and not undeservingly - for it is truly a language with which one almost enjoys being given a new problem to solve. There’s in general no good reason to modify a parameter, except for the following idiom: This could be replaced by a slightly different idiom: My main complaint is threading, which is not as performant in many circumstances (compared to Java, C and others) due to the global interpreter lock (see "Inside the Python GIL" (PDF link) talk). Strait-jacket (there's only one way to do it). Personally I think that incompatibility between between 2.x and 3.x is one of Python’s biggest advantages. (12 replies) One drawback of python I recently realised is that it takes away a lot of fun in 'other' programming languages. You're free to not. regarding the scoping, it might worth it for the curious to look at. Might I suggest using a good python IDE for that? We solved the problem of multicollinearity. As a result, Python's version is much less problematic then those ones. To me, enforced access controls fall into the same bucket as static typing: they do help in providing some additional confidence in correctness (but not enough to avoid the need for extensive testing), but at a high cost in development productivity. Similarly, Python doesn't quite get the message-passing aspect of OOP right, either. Next time I do a project in Python, I'll try it out. At the very least, functional languages like F# have all the functions properly namespaced in modules: So they aren't all together. Python is a high-level programming language that has English-like syntax. This is exactly why it is a drawback. Python programming is a high-level, interpreted, and general-purpose dynamic programming language that focuses on code readability. Threading (I know its been mentioned already, but worth mentioning in every post). But it has some great redeeming features: I do favor python and the first disadvantage that comes to my mind is when commenting out a statement like if myTest(): then you must change the indentation of the whole executed block which you wouldn't have to do with C or Java. I find python's combination of object-oriented this.method() and procedural/functional method(this) syntax very unsettling: This is particularly bad because a large number of the functions (rather than methods) are just dumped into the global namespace: methods relating to lists, strings, numbers, constructors, metaprogramming, all mixed up in one big alphabetically-sorted list. Running "python foo.py" from the command line is different from "import foo". Python programmers face several issues regarding the design of the language. During a developer discussion our high level developer team reached the same conclusion though. You can use it as a plain dict-like Trie or convert a Trie to an automaton for efficient Aho-Corasick search. Arguably, the lack of static typing, which can introduce certain classes of runtime errors, is not worth the added flexibility that duck typing provides. The standard implementation of Python produces, when you run an application, a compiled version of the source code called byte code (with the extension .pyc ), which is then run by the Python interpreter. However, this flexibility means that Python does not offer some features common to statically typed OO languages. This means that tail-recursing on large structures can cost O(n) memory (because of the unnecessary stack that is kept) and will require you to rewrite the recursion as a loop to get O(1) memory. 2. Sudoku Solver in Python Posted on 27 July, 2020 . Here are the advantages and disadvantages of using Python in the corporate environment. Anyways, what you mean it's useful only for application programming? @Roger: the convention on SO is to comment downvotes. Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. +1 for pylint. they should be read-only. This is correct, though there are tools like PyChecker which can check for errors a compiler in languages like C/Java would do. I can't find the article quickly, but there's a email posting from Guido van Rossum that explains nicely why the "self" parameter is required. This flexibility of global variable may sometime render an unexpected output. I also find the index on these pages hard to read, and it's sometimes difficult to tell which section I want. Need to write threading primitives or kernel code or something? Flexible authentication and authorization. Also, multithreading seems to work fine if you use Jython instead of the reference CPython implementation. Drawback of ‘global’ statement. I really disagree on the critique of the documentation, I think it is excellent and better than most if not all major languages out there. In stacks, objects are stored one over another, and these objects get removed in the reverse order of the arrival i.e. What problems will a person with purple blood (hemerithrin instead of hemoglobin) have? @limscoder: if you want to see easy unicode, try Tcl. Bisection Method Disadvantages (Drawbacks) In Numerical analysis (methods), Bisection method is one of the simplest and convergence guarenteed method for finding real root of non-linear equations. With the ahocorasick.Automaton class, you can find multiple key strings occurrences at once in some input text. I think it would be better if it created a new list object whenever a default argument was required (rather than creating a single object to use for every function call). It supports C, Java, Javascript, Python, Ruby and Scheme. Multiple dispatch does not integrate well with the established single-dispatch type system and is not very performant. Pick any Skill to Practice from a wide range of options available. The major drawback of symmetric cryptography is that if the key is leaked to the intruder, the message can be easily changed and this is considered as a risk factor. sentence=str(input("Enter sentence") words=sentence.split() uword=input("enter word from sentence") if uword in words: print("Word is in sentence") else: print("Word isn't in sentence") What is Python? Regarding your problem with the explicit self keyword. Python has many fans in the open source community, but is it ready for the enterprise? Some global functions, such as len, that you'd expect to be a method (which it actually is behind the scenes). Set comprehensions in Python can be constructed as follows: {skill for skill in ['SQL', 'SQL', 'PYTHON', 'PYTHON']} The output above is a set of 2 values because sets cannot have multiple occurences of the same element. Python's scoping is badly broken, which makes object-oriented programming in Python very awkward. Nothing in Python prevents me form overwriting or reusing variables. The "straight-jacket" prevents all sorts of syntax wars. C# is better than Python because ... yadda yadda yadda) - more of an objective (to some level) opinion which language features are badly designed, whether, what are maybe some you're missing in it and so on. In summary, I’d like to have two keywords in the language: var and let. (*= For the nitpickers: I mean concurrency which is at least partially parallel. Critique is out-of-scope, it's there, it's widely used, but it makes the python culture confusing ( it hurts the motto that says " There should be one-- and preferably only one --obvious way to do it "). It's just a strange behavior that doesn't match what you would expect and isn't useful for a large number of circumstances. Project details.
