version capatibility

Supported Ubuntu and Python Versions

[!NOTE|label:references:]

• Ubuntu releases
• NOTE: Python2.7 (all), Python 3.6 (bionic), Python 3.8 (focal), Python 3.10 (jammy) are not provided by deadsnakes as upstream ubuntu provides those packages.

list included modules

$ python -c 'help("modules")'

Please wait a moment while I gather a list of all available modules...

__future__          _warnings           graphlib            runpy
_abc                _weakref            grp                 sched
_aix_support        _weakrefset         gzip                secrets

list lib paths

$ python -c 'import sys; print (sys.path)'
['', '/usr/lib/python39.zip', '/usr/lib/python3.8', '/usr/lib/python3.8/lib-dynload', '/usr/local/lib/python3.8/dist-packages', '/usr/lib/python3/dist-packages']

Positional notation

to Binary

• octal to binary

  >>> bin( int('0o10', 8) )
  '0b1000'
  >>> bin( int('0o17', 8) )
  '0b1111'
  

• decimal to binary

  >>> bin(2)
  '0b10'
  >>> bin(10)
  '0b1010'
  

  • or

    >>> format( 3, 'b' )
    '11'
    >>> format( 15, 'b' )
    '1111'
    

• hexadecimal to binary

  >>> bin( int('a', 16) )
  '0b1010'
  >>> bin( int('f', 16) )
  '0b1111'
  

to Octal

• binary to octal

  >>> oct( int(str(111), 2) )
  '0o7'
  >>> oct( int(str(1000), 2) )
  '0o10'
  

• decimal to octal

  >>> oct(8)
  '0o10'
  

  • or

    >>> format( 15, 'o' )
    '17'
    >>> format( 8, 'o' )
    '10'
    

• hexadecimal to octal

  >>> oct( 0xf )
  '0o17'
  

to Decimal

• binary to decimal

  >>> int( str(11), 2 )
  3
  >>> int( str(1010), 2 )
  10
  

• octal to decimal

  >>> 0o10
  8
  >>> int( 0o10 )
  8
  >>> int ( str(10), 8 )
  8
  

• hexadecimal to decimal

  >>> int( 0xf )
  15
  

to Hexadecimal

• binary to hexadecimal

  >>> hex( int(str(1010), 2) )
  '0xa'
  >>> hex( int(str(1111), 2) )
  '0xf'
  

• octal to hexadecimal

  >>> hex(0o10)
  '0x8'
  >>> hex( int('0o17', 8 ))
  '0xf'
  

• decimal to hexadecimal

  >>> hex(15)
  '0xf'
  >>> hex(66)
  '0x42'
  

  • or

    >>> format( 15, 'x' )
    'f'
    

  • or

    >>> '%x' % 15
    'f'
