it will suggest the SMTP port, and OAuth 2.0 for authentication

redirecting to https://www.google.com/accounts/Logout?continue=https://console.developers.google.com/start/api?id=gmail

register for google API,

register for Authorized JavaScript origins, and Authorized redirect URI in google’s API page

git command

Git task Notes Git commands
Tell Git who you are Configure the author name and email address to be used with your commits.

Note that Git strips some characters (for example trailing periods) from user.name.

 git config --global user.name "Sam Smith"

git config --global user.email sam@example.com
Create a new local repository git init
Check out a repository Create a working copy of a local repository: git clone /path/to/repository
For a remote server, use: git clone username@host:/path/to/repository
Add files Add one or more files to staging (index): git add filename
Commit Commit changes to head (but not yet to the remote repository): git commit -m "Commit message"
Commit any files you’ve added with git add, and also commit any files you’ve changed since then: git commit -a
Push Send changes to the master branch of your remote repository: git push origin master
Status List the files you’ve changed and those you still need to add or commit: git status
Connect to a remote repository If you haven’t connected your local repository to a remote server, add the server to be able to push to it: git remote add origin <server>
List all currently configured remote repositories: git remote -v
Branches Create a new branch and switch to it: git checkout -b <branchname>
Switch from one branch to another: git checkout <branchname>
List all the branches in your repo, and also tell you what branch you’re currently in: git branch
Delete the feature branch: git branch -d <branchname>
Push the branch to your remote repository, so others can use it: git push origin <branchname>
Push all branches to your remote repository: git push --all origin
Delete a branch on your remote repository: git push origin :<branchname>
Update from the remote repository

 

 Fetch and merge changes on the remote server to your working directory: git pull
To merge a different branch into your active branch: git merge <branchname>
View all the merge conflicts:

View the conflicts against the base file:

Preview changes, before merging:

 git diff

git diff --base <filename>

git diff <sourcebranch> <targetbranch>
After you have manually resolved any conflicts, you mark the changed file: git add <filename>
Tags You can use tagging to mark a significant changeset, such as a release: git tag 1.0.0 <commitID>
CommitId is the leading characters of the changeset ID, up to 10, but must be unique. Get the ID using: git log
Push all tags to remote repository: git push --tags origin
Undo local changes If you mess up, you can replace the changes in your working tree with the last content in head:

Changes already added to the index, as well as new files, will be kept.

 git checkout -- <filename>
Instead, to drop all your local changes and commits, fetch the latest history from the server and point your local master branch at it, do this: git fetch origin

git reset --hard origin/master
Search Search the working directory for foo(): git grep "foo()"

__init__.py

from here

What is __init__.py used for?

The primary use of __init__.py is to initialize Python packages. The easiest way to demonstrate this is to take a look at the structure of a standard Python module.

package/
    __init__.py
    file.py
    file2.py
    file3.py
    subpackage/
        __init__.py
        submodule1.py
        submodule2.py

As you can see in the structure above the inclusion of the __init__.py file in a directory indicates to the Python interpreter that the directory should be treated like a Python package

 

What goes in __init__.py?

__init__.py can be an empty file but it is often used to perform setup needed for the package(import things, load things into path, etc).

One common thing to do in your __init__.py is to import selected Classes, functions, etc into the package level so they can be convieniently imported from the package.

In our example above we can say that file.py has the Class File. So without anything in our__init__.py you would import with this syntax:

from package.file import File

However you can import File into your __init__.py to make it available at the package level:

# in your __init__.py
from file import File

# now import File from package
from package import File

Another thing to do is at the package level make subpackages/modules available with the__all__ variable. When the interpeter sees an __all__ variable defined in an __init__.py it imports the modules listed in the __all__ variable when you do:

from package import *
__all__ is a list containing the names of modules that you want to be imported with import * so looking at our above example again if we wanted to import the submodules in subpackage the __all__ variable in subpackage/__init__.py would be:

__all__ = ['submodule1', 'submodule2']
With the __all__ variable populated like that, when you perform

from subpackage import *
it would import submodule1 and submodule2.

As you can see __init__.pycan be very useful besides its primary function of indicating that a directory is a module.

To determine if a character is Chinese

string’scoding should be unicode

to know if one character is Chinese

we can decode utf-8 to unicode

def is_chinese(uchar):
"""判断一个unicode是否是汉字"""
if uchar >= u'\u4e00' and uchar<=u'\u9fa5':
return True
else:
return False

 

In Python, convert utf-8 to unicode

string.decode('utf-8')

convert unicode to utf-8

string.encode('utf-8')

 

for i in '下：@uVT4HLJLA： 二、我是用MAC的，所以可以骂你脑残'.decode('utf-8'):
    print i, is_chinese(i)


下 True
： False
@ False
u False
V False
T False
4 False
H False
L False
J False
L False
A False
： False
  False
二 True
、 False
我 True
是 True
用 True
M False
A False
C False
的 True
