1. I wanted to install SCIM under Ubuntu12 and uninstalled ibus, but it failed. . . After giving up for a while and trying to update in English, I found that I couldn’t keep up with English. Finally, I silently installed ibus back. . .
sudo apt-get install ibus-gtk ibus-qt4 ibus-pinyin ibus-pinyin-db-open-phrase
sudo apt-get install ibus-pinyin ibus-pinyin-db-android
Later start ibus, at the keypad logo Set the input method of preferences of ibus, and finally set the language support of system to ibus
2. As a newbie, continue to learn django from the awesome website:
2.1 Download the bootstrap appearance design package (http://twitter.github.io /bootstrap/)
2.2 Place the compressed bootstrap.min.css under the static/css of the project, and configure the project’s settings.py{
STATICFILES_DIRS = (
# Put strings here, like "/home/html/static " or "C:/www/django/static".
# Always use forward slashes, even on Windows.
# Don't forget to use absolute paths, not relative paths.
'/media/DATA/MyDocuments/python_ubuntu/ django/myproject'+STATIC_URL,)
}
Follow urls.py{
urlpatterns+=staticfiles_urlpatterns()
}
(I want to follow the expert’s guidance os.path.dirname(__file__), but it has not been successful, so I want to run the settings.py file When printing, I found that it is empty. I checked the information and found that if the script is run with a relative path, then it is an empty directory. If it is run with a full path, then the full path where it is is output. I can only say that my learning is very sloppy. )
2.3 Continue learning and implement form verification

In Python 3, two lists can be connected through a variety of methods: 1) Use operator, which is suitable for small lists, but is inefficient for large lists; 2) Use extend method, which is suitable for large lists, with high memory efficiency, but will modify the original list; 3) Use * operator, which is suitable for merging multiple lists, without modifying the original list; 4) Use itertools.chain, which is suitable for large data sets, with high memory efficiency.

Using the join() method is the most efficient way to connect strings from lists in Python. 1) Use the join() method to be efficient and easy to read. 2) The cycle uses operators inefficiently for large lists. 3) The combination of list comprehension and join() is suitable for scenarios that require conversion. 4) The reduce() method is suitable for other types of reductions, but is inefficient for string concatenation. The complete sentence ends.

Key features of Python include: 1. The syntax is concise and easy to understand, suitable for beginners; 2. Dynamic type system, improving development speed; 3. Rich standard library, supporting multiple tasks; 4. Strong community and ecosystem, providing extensive support; 5. Interpretation, suitable for scripting and rapid prototyping; 6. Multi-paradigm support, suitable for various programming styles.

Python is an interpreted language, but it also includes the compilation process. 1) Python code is first compiled into bytecode. 2) Bytecode is interpreted and executed by Python virtual machine. 3) This hybrid mechanism makes Python both flexible and efficient, but not as fast as a fully compiled language.
