![]() ![]() To solve the high computations from Physics and Mathematics, this library is widely used by researchers. It is widely used in Deep Learning algorithms and Machine Learning. It is used for high level computations and it is an Open Source Library. TensorFlow: it was developed by “Google” in collaboration with “Brain Team”.For easy computation purposes it has built-in – built mathematical functions. Numpy: Numerical Python (Numpy) is a library which supports multi – dimensional data and large matrices.The operations like Iteration, Concatenation, Re-indexing, Data Conversion, Data Visualization, Aggregations etc are supported by the Pandas library. The essential steps such as analyzing the data, data manipulation and data cleaning are performed in Pandas. Pandas: it is one of the most important libraries which are widely used by Data Scientist and Software developers.Some of the common libraries used in Python are as described below Python is portable which allows the developers to be more productive in the sense of software development and deployment.Python is very easy to learn and it is also called the “Beginners Programming Language”.Python has a wide range of libraries which can be used when necessary.Python has a number of factors and some of them are listed below To make Python a high programming language all the core modules work together. The standard library in Python contains about 200 core modules. The libraries of Python are basically written in C language. The syntax, semantics and tokens are contained by the Python Standard Libraries. All the library files have DLL (Dynamic Load Libraries) extension and when a program is linked to a particular library then the linker will automatically reach to that library and finally the program is executed. In the field of Data Science, Machine Learning and Data Visualization libraries play a very important role. Libraries in Python make programming convenient and simple for programmers to perform their task in less time. Generally, a library may also contain configuration data, a huge amount of documentation, templates and classes etc. In the world of programming, a library consists of a number of precompiled codes which can be used to perform a specific task in the program. The first step is to build the find command to locate all the links we want to delete: $ find. Next, let’s see how we achieve the goal using the find | xargs rm (or unlink) combination. For example, we should keep the regular file 2bDeleted_I_am_not_a_link.txt intact, even though its name begins with “ 2bDeleted“. ![]() We should be careful that we only want to remove symbolic links. Our goal is to recursively remove all symbolic links whose names match the pattern “ 2bDeleted*“. Also, some link names are with the pattern “2bDeleted*”, while other link names follow the pattern “ keepMe*“. The output above shows that we have multiple links in the current directory and the sub-directory “aDir”. It’s worth mentioning that if we pass the name of a regular file to the unlink command, it’ll delete the file, even though it’s not a link: $ unlink aFile.txtĭrwxr-xr-x 3 kent kent 60 Apr 27 00:22. Therefore, we should only pass the link name to unlink: $ unlink dirLink Similarly, if we pass a name ending with a slash, the unlink command refuses to remove the link, too. Unlink: cannot unlink 'dirLink/': Not a directory ![]() Now, let’s try passing “dirLink/” to unlink to see if it can remove the link: $ unlink dirLink/ The command is pretty straightforward, and it works. Lrwxrwxrwx 1 kent kent 4 Apr 27 00:15 dirLink -> aDir/ rw-r-r- 1 kent kent 0 Apr 26 23:46 aFile.txt Let’s re-create the two links and try to delete them using the unlink command.įirst, we’re going to delete the fileLink link: $ unlink fileLinkĭrwxr-xr-x 2 kent kent 40 Apr 26 23:48 aDir/
