Python - None - equivalent of NULL

-

None


The None object is used to represent the absence of a value. 
It is similar to null in other programming languages. 
Like other "empty" values, such as 0, [] and the empty string, it is False when converted to a Boolean variable. 
When entered at the Python console, it is displayed as the empty string.
>>> None == None
True
>>> None
>>> print(None)
None
>>>
The None object is returned by any function that doesn't explicitly return anything else.
def some_func():
print("Hi!")

var = some_func()
print(var)
Result:>>>
Hi!
None
>>>

Python - Argument Passing

-
Argument Passing When known to the interpreter, the script name and additional arguments thereafter are turned into a list of strings and assigned to the  argv  variable in the  sys  module. You can access this list by executing  import   sys . The length of the list is at least one; when no script and no arguments are given,  sys.argv[0]  is an empty string. When the script name is given as  '-'  (meaning standard input),  sys.argv[0]  is set to  '-' . When  -c   command  is used,  sys.argv[0]  is set to  '-c' . When  -m   module  is used,  sys.argv[0]  is set to the full name of the located module. Options found after  -c   command  or  -m module  are not consumed by the Python interpreter’s option processing but left in  sys.argv  for the command or module to handle.

Python - How to Escape special characters in String

-
Besides numbers, Python can also manipulate strings, which can be expressed in several ways. They can be enclosed in single quotes ( '...' ) or double quotes ( "..." ) with the same result  [2] .  \  can be used to escape quotes: >>> 'spam eggs' # single quotes 'spam eggs' >>> 'doesn \' t' # use \' to escape the single quote... "doesn't" >>> "doesn't" # ...or use double quotes instead "doesn't" >>> '"Yes," he said.' '"Yes," he said.' >>> " \" Yes, \" he said." '"Yes," he said.' >>> '"Isn \' t," she said.' '"Isn\'t," she said.' If you don’t want characters prefaced  with  \  to be interpreted as special characters, you can use  raw strings  by adding  an  r  before  the first quote: >>>...
