Print all properties of a Python Class

Question

I have a class Animal with several properties like    class Animal object       def   init   self           self legs   2         self name    Dog          self color   Spotted          self smell   Alot          self age    10         self kids   0          many more      I now want to print all these properties to a text file  The ugly way I m doing it now is like    animal Animal   output    legs  d  name  s  color  s  smell  s  age  d  kids  d     animal legs  animal name  animal color  animal smell  animal age  animal kids     Is there a better Pythonic way to do this

try ppretty   from ppretty import ppretty   class Animal object       def   init   self           self legs   2         self name    Dog          self color   Spotted          self smell   Alot          self age    10         self kids   0   print ppretty Animal    seq length 10    Output     main   Animal age   10  color    Spotted   kids   0  legs   2  name    Dog   smell    Alot

Another way is to call the dir   function  see https   docs python org 2 library functions html dir    a   Animal   dir a      gt  gt  gt      class        delattr        dict        doc        format        getattribute         hash        init        module        new        reduce        reduce ex          repr        setattr        sizeof        str        subclasshook          weakref      age    color    kids    legs    name    smell     Note  that dir   tries to reach any attribute that is possible to reach   Then you can access the attributes e g  by filtering with double underscores   attributes    attr for attr in dir a                 if not attr startswith          This is just an example of what is possible to do with dir    please check the other answers for proper way of doing this

Just try beeprint  it prints something like this   instance Animal       legs  2      name   Dog       color   Spotted       smell   Alot       age  10      kids  0    I think is exactly what you need

Maybe you are looking for something like this        gt  gt  gt  class MyTest          def   init    self               self value   3      gt  gt  gt  myobj   MyTest        gt  gt  gt  myobj   dict         value   3

In this simple case you can use vars     an   Animal   attrs   vars an      kids   0   name    Dog    color    Spotted    age   10   legs   2   smell    Alot     now dump this in some way or another print      join   s   s    item for item in attrs items       If you want to store Python objects on the disk you should look at shelve     Python object persistence
