Python was first published by Guido van Rossum in 1991 and which was mean t to be a replacement for the ABC language. Python is versatile, interpreted, high level, and dynamically typed. It is also object oriented and designed on code readability. To this extent, it has good and built-in spaces that indent the code much better.
Python is open source for commercial projects and in any case under the GPL license. It also has many advantages; as a rich standard library and garbage collection. Python can also incorporate many other languages and platforms - shapes using third party modules pypi (PyPI). Python is arguably the language of choice for software developers in the field of artificial intelligence or machine learning .
Python vs Node.js Comparison
Node.js vs Python: typing-and- syntax
Python is easy to learn. It is highly recommended as a first language because it is so easy to learn while teaching programming basics and is a useful language if you are inexperienced or one. Professional Python
Python is also built on readability, it’s built into Python’s DNA. For example, instead of braces to delimit blocks and lines of code, Python uses dashes. Python should be indented at work, so all code written in Python will be more readable and cleaner than code in a language that doesn’t use indentation. It is also much more forgiving in other ways, such as not using the semicolon.
Python vs Node.js: performance < / h3>
It is important to note however that Python does not take long. It is only slow compared to Node.js to crunch a lot. for most random applications the difference will be infinitely small and will continue to be indistinguishable until when it is not applied on a large scale. this mean s that if you try to manage the traffic like Google or Facebook are, or try counting of huge data sets, you probably will not waste a large part of the day in the course of running Python on Node. js.
in Python you have a springboard to get into data science, and even if you choose not to use work done by others, the information about Python and data science is much richer. Python is currently one of the favorite tools for data science, so even finding information on how to apply it this way is not difficult. in comparing the two for the science data is like comparing a room and an electric drill. The two can turn a screw, but it will be much easier on your wrist.
on the web
The back end is the side of the internet you can’t see. It handles the raw information that we put in the sites, so if the front is a sink, then the back end is the pipes.
Node.js is also preferable for its speed and hasty performance, which is useful for real-time applications, such as instant messaging or chat. For this reason, it is also useful for high load applications or supplier applications where processing speed is important (such as booking a ticket).
Python still has a few advantages for the back end. Python is reliable and consistent. It’s also easier to use and set up, and more beginner- friendly . It is also preferable that its scientific background; whether your back end needs to run data science, machine learning applications , or needs to work with big data,then Python will work fine for you.
Removing white space around a saved image in matplotlib
I need to take an image and save it after some process. The figure looks fine when I display it, but after saving the figure, I got some white space around the saved image. I have tried the "tight" option for savefig method, did not work either. The code:
I cannot claim I know exactly why or how my “solution” works, but this is what I had to do when I wanted to plot the outline of a couple of aerofoil sections — without white margins — to a PDF file.
(Note that I used matplotlib inside an IPython notebook, with the -pylab flag.)
I have tried to deactivate different parts of this, but this always lead to a white margin somewhere. You may even have modify this to keep fat lines near the limits of the figure from being shaved by the lack of margins.
