Disable the below message in gitlab if your are annoyed with it like me:

Go to your project settings and uncheck:

Create an excel file using pandas in python:

users = [{
     'user_id': 1
 }, {
     'user_id': 2
 }]
 df = pandas.DataFrame(users, columns=['user_id'])
 filename = 'users_info_%s.xlsx' % random.randint(0, 100)
 writer = pandas.ExcelWriter(filename, engine='xlsxwriter')
 df.to_excel(writer, sheet_name='user information')

tmux is a terminal multiplexer. It lets you switch easily between several programs in one terminal, detach them (they keep running in the background) and reattach them to a different terminal.
after installation you can list your sessions by:

tmux ls

Output would be something like this:

0: 1 windows (created Mon Aug  7 10:34:00 2017) [135x52] (attached)
 2: 1 windows (created Mon Aug  7 13:56:10 2017) [126x25]

(attached) at the end of session 0 tells us that the session has been attached by a user.
You can attach a session by:

tmux attach -t 0

-t tells tmux which session should be attached.

Now let's say you want to detach a session you need to press ^b+d (CONTROL+b and then press d).

If you want to split your window to multiple panes press ^b+" (split horizontally) and/or ^b+% (split vertically).

^b+n : next window
^b+(up/down/left/right) : to move between panes
^b+? : help and shortcuts
^b+x : kill a pane

THE GREAT THING about tmux is that multiple users can attach the same session and work simultaneously!

I know you will get tired if I say more about tmux, so go and explore more yourself and see the real power of multiplexers.

You can add title to iOS push notification as of iOS 8.2:

A short string describing the purpose of the notification. Apple Watch displays this string as part of the notification interface. This string is displayed only briefly and should be crafted so that it can be understood quickly. This key was added in iOS 8.2.

#push #notification #ios

As you all may know pip is a python package manager and everyone has worked with it to install python libs.

Some of the commands with pip that you may not know about it:

- freeze: output installed packages in requirements format. (you can grep and search for a specific package):

         rply==0.7.4
         rsa==3.2.3
         sasl==0.2.1
         scipy==0.13.0b1

- list: list installed packages:

tcpwatch (1.3.1)
         telebot (0.0.3)
         thrift (0.9.3)

- show: Show information about installed packages:

$ pip show pandas
         Name: pandas
         Version: 0.17.0
         Summary: Powerful data structures for data analysis, time series,and statistics
         Home-page: http://pandas.pydata.org
         Author: The PyData Development Team
         Author-email: pydata@googlegroups.com
         License: BSD
         Location: /Library/Python/2.7/site-packages
         Requires: numpy, python-dateutil, pytz

Important note for devops: pip by default install a stable version of the package. If you need to install an unstable version of the package (latest version) use --pre flag to install pre-release package.

If you want to manage your custom python repository package versions (RC, Alpha, Beta, Stable, etc) add classifiers to your setup.py script like below:

setup(...,
       classifiers=[
           'Development Status :: 4 - Beta',
           'Environment :: Console',
           'Environment :: Web Environment',
           'Intended Audience :: End Users/Desktop',
           'Intended Audience :: Developers',
           'Intended Audience :: System Administrators',
           'License :: OSI Approved :: Python Software Foundation License',
           'Operating System :: MacOS :: MacOS X',
           'Operating System :: Microsoft :: Windows',
           'Operating System :: POSIX',
           'Programming Language :: Python',
           'Topic :: Communications :: Email',
           'Topic :: Office/Business',
           'Topic :: Software Development :: Bug Tracking',
           ],
       )

The important part is Development Status :: 4 - Beta, which for stable release you would use Development Status :: 5 - Production/Stable.

To see list of pypi Development Status values read from the below link:
https://pypi.python.org/pypi?%3Aaction=list_classifiers

Now you can give versioning like Django 2.0b1 (for pre release) and Django 1.11.6 for stable release.
To see different classifiers see the link Django link below to learn more:

pip install from git repository:

put a key in dictionary into another key and remove it from dictionary:

Idiots way:

data = {
     'username': 'alireza@gmail.com'
 }
 data['email'] = data['username']
 del data['username']

Tech C**P way:

data = {
     'username': 'alireza@gmail.com'
 }
 data['email'] = data.pop('username')

pop access the data and remove it from data payload. In case username is not in data, an error will be raised. To prevent such an error give it default value:

data['email'] = data.pop('username', 'NO_USERNAME')

There is a mgic method in python called contains which should return true if item is in self, false otherwise.
The method signature of contains:

object.__contains__(self, item)

Samples:

>>> 'sample_output'.__contains__('sample')
 True
 >>> 'sample_output'.__contains__('ASL')
 False

BUT DONT USE this magic methods this way, as it should be used in internal class operations.
Membership test operator for this is in. In case you want to test membership:

>>> 'sample' in 'sample_output'
 True
 >>> 'ASL' in 'sample_output'
 False

Side note: methods which are started by _ (underscore) should not be called directly outside of class scope. They meant for internal class operations.
