Shortcut: Alt + Enter: automatically add the package
2. "code completion" set the time delay

3. Pycharm default font size can not be changed by the Ctrl + wheel, can be set in Mouse>
4. Display "line numbers" and "blank character"

Here line breaks removed √, otherwise the bar, and baz will be separated on different lines, it does not look good.
File -> Settings -> appearance
1. Modify the IDE scheme shortcuts
> Keymap
1) execute selection in console : add keymap > ctrl + enter
The system comes with several shortcuts programs, drop-down box like "defaul", "Visual Studio", is very useful in finding Bug, "NetBeans 6.5", "Default for GNOME" and so on options,
Because "Eclipse" program more popular, but also more personal, and ultimately chose the "Eclipse".
There are a few common shortcuts do not like Eclipse, in order to modify the program must first copy of Eclipse:
(1) Code prompts, by default [Ctrl + Space], was replaced like Eclipse, that is, [Alt + /]
Main menu -> code -> Completion -> Basic -> set to "Alt + /"
Main menu -> code -> Completion -> SmartType -> 设置为“Alt+Shift+/”
But "Alt + /" default again
Main menu -> code -> Completion -> Basic -> Cyclic Expand Word occupied, first delete it say it (right-click Delete)!
(2) Close the current document, the default is [Ctrl + F4], was replaced like Eclipse, that is [Ctrl + W]
Main menu -> Window -> Active Tool Window -> Close Active Tab -> 设置为 “Ctrl+F4”;
Main menu -> Window -> Editor -> Close -> set to "Ctrl + W";
2. Set IDE skin theme
> Theme -> 选择“Alloy.IDEA Theme”
Or setting the search theme may change the subject, all unified color change
File > settings > build.excution
Automatically execute code every time you turn python console
> Console> pyconsole
SYS Import

Import OS
Print ( 'Current workdirectory:', The os.getcwd ())
AS NP numpy Import
Import SciPy AS SP
Import matplotlib MPL AS
If ipython installed, the more powerful the ipython in pyconsole
> console
选中use ipython if available
So every time you open pyconsole will open ipython
Note: ipython mounted in the virtualenv: (ubuntu_env) pika: / media / pika / files / mine / python_workspace / ubuntu_env $ pip install ipython

If you open the console will support multi-displays a django console in settings> build.excution>:
Django console settings are as follows
import sys
print('Python %s on %s' % (sys.version, sys.platform))

print('Django %s' % django.get_version())
sys.path.extend([WORKING_DIR_AND_PYTHON_PATHS])

pycharm environment and path configurations
python interpreter path
python interpreter program path
for python project execution path configuration python
For example, some items are running a system environment python2.7; some 3.4; some projects using virtualenv the python environment [python virtual environment configuration - pycharm in the project configuration]
In pycharm> file> settings> project: pythonworkspace> project interpreter> to select a corresponding item> project interpreter interpreter specified python
Run pycharm in configuration has an option to add content roots to pythonpath
After selecting a plurality sys.path will project the project path / media / pika / files / mine / python_workspace, which directory was used as a package, so that the package can not python by introducing the directory from SocialNetworks.SocialNetworks files.
However, preferably used sys.path.append (os.path.join (os.path.split (os.path.realpath (__ file __)) [0], "../ ..")) to add, so pycharm outside you can also run without error.
conduct python package management pycharm in
pycharm in the project can be included in package, directory (the directory name can have spaces), etc.
A certain py file in the package directory to call a function in another py file, first of all to directory to source root, in order from the first package first introduced correctly function, or how to introduce all wrong:
SystemError: Parent module '' not loaded, cannot perform relative import
Note: Directory> Right> make directory as> source root
python script interpreter path
when ctrl + shift + f10 / f10 python script execution
Cwd current working directory for the run / debug configurations in the working directory

And where you can configure
pycharm configuration os.environ environment
pycharm os.environ not be read in the terminal in the system environment variables
pycharm .bashrc parameters can not be read in os.environ
Use pycharm, or the use of dict os.environ returned are not provided in ~ / .bashrc is variable in terms of the module python console, but / etc / profile configuration variables. However, the use of the terminal in the python, os.environ but it can acquire the content ~ / .bashrc of.
Solution 1:
System environment settings in ~ / .bashrc can only run Spark program is available only in terminal shell, as .bashrc is only read for interactive shells.
If the current user is valid for the entire system (including pycharm like IDE), you should be in the system environment variable ~ / .profile file. If the whole system is set up for all users, modify / etc / profile or / etc / environment now.
As SPARK_HOME settings [Spark: errors related summary]
Solution 2: set in code, so that regardless of the environment there is no problem
# spark environment settings
import sys, os
os.environ['SPARK_HOME'] = conf.get(SECTION, 'SPARK_HOME')
sys.path.append(os.path.join(conf.get(SECTION, 'SPARK_HOME'), 'python'))
os.environ["PYSPARK_PYTHON"] = conf.get(SECTION, 'PYSPARK_PYTHON')
os.environ['SPARK_LOCAL_IP'] = conf.get(SECTION, 'SPARK_LOCAL_IP')
os.environ['JAVA_HOME'] = conf.get(SECTION, 'JAVA_HOME')
os.environ['PYTHONPATH'] = '$SPARK_HOME/python/lib/py4j-0.10.3-src.zip:$PYTHONPATH'
pycharm配置第三方库代码自动提示
Pycharm expand practical function
pycharm cleared compiled .pyc intermediate file
to select your workspace> Right> clean python compiled files
You can also write your own cleanup code
pycharm set up an external tool
[python Gadgets] pyc delete all files for the current pycharm py file opened in the corresponding directory. If it is run directly (instead of running the following tools in), then delete the E: \ pyc file in the mine \ python_workspace \ WebSite directory.
The above code is changed to delete external tool
PyCharm> settings> tools> external tools > + Add
Name: DelPyc
program: $ PyInterpreterDirectory $ / python Python installation path
Parameters: $ProjectFileDir$/Oth/Utility/DelPyc.py $FileDir$
Work directory: $FileDir$
Note: $ FileDir $ parameters behind Parameters is to say, DelPyc is delete all the files for the current pyc pycharm py file opened in the corresponding directory.
Then be directly executed by the following
Note: add a Tools named DelPycIn
program: Python installation path, eg D: \ python3.4.2 \ python.exe
Parameters: E:\mine\python_workspace\Utility\DelPyc.py
Work directory using the variable $ FileDir $
There are no parameters $ FileDir $, so you can delete commonly used directories r'E: \ mine \ python_workspace \ WebSite ', the two together with a more convenient
Code quality
when you are typing, PyCharm will check your code meets PEP8. It will let you know if you have too many spaces or blank lines, and so on. If you wish, you can configure PyCharm pylint run as an external tool.
python2 turn python3 fastest way to
/ usr / bin / 2to3 -wn $ FileDir $
This opens the pycharm in a file, right-py2 all external tools> py2topy3 can instantly current file directory into py3, is not very witty!
