Yaaaaa!!!! it was my first PyCon India. One day I was chatting to Sayan and suddenly he told me that start saving some money from now and attend the pycon India this year. I had never been any kind of conference ever before so I was bit hesitated about this conference but Sayan and other folks from dgplug guided me a lot. I started my journey with my dad from Kolkata on 10th October and reached Chennai on 11th.
On 12th October I left for the conference. When I reached the conference I saw sourabh, Pravar and Rayan there and talked with them. After that I got my attendee card then went for the breakfast and while eating I met some people and talked with them like Vijay, Noah later I proceeded to the conference. After that I attended the Jake VanderPlas’s keynote. After that I was going to various sponsors booth to collect the goodies :p. After that I went for Pradyun’s talk Python Packaging – where we are and where we’re headed. He described how packaging works with pip and how they are planning to move ahead. I met many of the faces whom I used to know on IRC/Twitter only. Later me and Sayan explored the Poster Session. It was really exciting and my first day of the conference was over. After the conference me and some other folks went for visiting the Palavakkam Beach and spent some good time there.
On 13th it started with keynote by Ines Montani. After that there was annual DGPLUG staircase meeting. Sayan conducted the meeting and we all introduced our self to each other and discussed about what went wrong to this year’s summer training. We also discussed about the tasks given by Sayan this year. After finishing the lunch we also solved some word puzzles and coding questions to get the t-shirts and swags. The conference ended with David Beazley keynote and he live coded a stack machine, wrote an interpreter for Web Assembly game that was initially written for Rust in Python and in the end added PyGame to make it into an actual game. I was amazed after seeing it. The keynote ended with standing ovation from all the people in the hall. After the conference we went for DGPLUG dinner and spent some good time with other folks and had our dinner there.
On 14th(my birthday :p) morning I left for IIT Madras Research Park and in the morning there was my workshop on docker. After finishing the workshop I joined devsprint. There was lots of mentors conducting the devsprint and from that I choosed to join the Python Packaging Sprint which was conducted by Pradyun. It was my first devsprint and I didn’t even know anything about it but Pradyun helped me a lot understand the issue and what should be my approach to solve that. after the devsprint we went for dinner again. On that day most of my friends were returning so it was time to say goodbye to them 🙂
On 15th again there was devsprint happening there and I was solving an issue in pip and Pradyun was helping me regarding that issue. Besides devsprint me and Sourabh was discussing about some security stuff. After the devsprint I talked with other people.
Pycon India has gave me the opportunity to communicate and meet people from all across the world as well as different background. I got to know about lots of new technologies and other technical stuff. I made lots of new friends there and I returned home with some great memories with me 🙂 . If I go next year then I would like to be a volunteer there.
Most of us use git as their version control system and in day to day life while developing any application we commit our changes quite frequently. We follow the traditional way of committing changes like below –
$ git commit -m "Our commit message"
But we have another cool option to do this commit. We can use our favorite text editor for this commit. We have to first tell git that pop up the text editor every time you commit changes. For this execute below command in your terminal –
$ git config --global core.editor "vim"
Here it will pop up the vim text editor when you will execute git commit.
In this series the main focus was to build an simple pascal interpreter by python which can execute simple pascal codes like mathematical operations and procedure calling. This series introduced me lots of thing like scanner, token, parser, interpreter and grammar, etc. At first I was thinking that I will not be able to complete the series properly as I didn’t know anything about interpreter and compiler but as move forward in this series things get cleared because everything was elaborated properly. Whenever I stuck at any point I search it in the internet and try to find the proper solution. For me in this series the most interesting part was the grammar of any programming language and how they help.
In this series I also learned how to write better commits so people can understand my code and also learned how to reset my commit to previous commit when I commit wrong things or made any bad commit message. Here you can see my commits.
I was reading this part of the pym book and thought that I should change this code a little bit so that it can do some better thing like instead of storing the content in a text file it stores it in a HTML file and it also checks if there is any same named file exists in the directory or not. Here is the code –
Download the given url and saves it to the current directory
:arg url: URL of the file to be downloaded.
req = requests.get(url)
if req.status_code == 404:
print('No such file found at %s' % url)
fileName = url.split('/')[-1].split('.') + '.html'
print('Same file name already exist')
with open(fileName, 'wb') as fobj:
if __name__ == "__main__":
url = input("Enter a URL: ")
Above we are getting the content of the content of the url by requests.get(url) method. Then checking if that url is valid or not. If valid then parsing the url by split() method like first we are splitting it by “/” and taking the last value of the list and then splitting it again with “.” and taking the first value of the list. Then checking if there is no same name file exist and if there is no same name file then we are creating a file then writing the content in the file. Thank you 🙂
