You can also use regular expressions to split a string. For example,
import re
data = re.split(r'\s+', 'James 94 Samantha 417 Scarlett 74')
print( data )
# Output: ['James', '94', 'Samantha', '417', 'Scarlett', '74']
You can get rid of manage.py and use the django-admin command instead. To do so, you will have to manually do what manage.py does:
Add your project path to your PYTHONPATH
Set the DJANGO_SETTINGS_MODULE
export PYTHONPATH="/home/me/path/to/your_project"
export DJANGO_SETTINGS_MODULE...
If you have a vsix file, you can install it by running the file.
Get the vsix file (this is the extension installer)

To add annotations, hints, or exclude some code from being executed JavaScript provides two ways of commenting code lines
Single line Comment //
Everything after the // until the end of the line is excluded from execution.

It is not possible to use eval or exec to execute code from untrusted user securely. Even ast.literal_eval is prone to crashes in the parser. It is sometimes possible to guard against malicious code execution, but it doesn't exclude the possibility of outright crashes in the parser or the tokenizer....
In oracle, the difference (in days and/or fractions thereof) between two DATEs can be found using subtraction:
SELECT DATE '2016-03-23' - DATE '2015-12-25' AS difference FROM DUAL;
Outputs the number of days between the two dates:
DIFFERENCE
----------
89
And:
SELECT TO_DATE( '201...
Enum classes can also declare members (i.e. properties and functions). A semicolon (;) must be placed between the last enum object and the first member declaration.
If a member is abstract, the enum objects must implement it.
enum class Color {
RED {
override val rgb: Int = 0xFF0000

In the simplest use-case, just navigate to the directory your file is in, and type:
pyinstaller myfile.py
Pyinstaller analyzes the file and creates:
A myfile.spec file in the same directory as myfile.py
A build folder in the same directory as myfile.py
A dist folder in the same directory as m...
You can use the .Net Math class to do calculations ([System.Math])
If you want to know which methods are available you can use:
[System.Math] | Get-Member -Static -MemberType Methods
Here are some examples how to use the Math class:
PS C:\> [System.Math]::Floor(9.42)

Any predicate function can be used as a spec. Here's a simple example:
(clojure.spec/valid? odd? 1)
;;=> true
(clojure.spec/valid? odd? 2)
;;=> false
the valid? function will take a spec and a value and return true if the value conforms to the spec and false otherwise.
One other inte...
You can use the ** keyword argument unpacking operator to deliver the key-value pairs in a dictionary into a function's arguments. A simplified example from the official documentation:

Sometimes what you want to do is just too complex for a filter or a simple_tag. Fow this you will need to create a compilation function and a renderer.
In this example we will create a template tag verbose_name with the following syntax:
