How to correct, save, run with ptpython

[sylas]

Hi all. I am Administrator. With Notepad: I go to correct the error, then I click on "save" icon, then I go to Command Prompt and run with "python Filename".

But with ptpython , where to correct, where to save, where to run.
Beside that , At the bottom, right corner I have "Meta+Enter Execute". What is it ?
Also at the bottom I have "History". I should like to use that, but I don't know how.

Error:

λ ptpython                              
>>> class Selfless:

...         self.data=data              
...     def selfless(arg1,arg2):        
...         return arg1+arg2

self is always lowercase.

class Selfless:
    def __init__(self, data):
        self.data = data

    def selfless(self, arg1, arg2):
        return arg1 + arg2

    def normal(self, arg1, arg2):
        return self.data + arg1 + arg2

So now copy into ptpython,just Enter after copy in will execute class Selfless:

C:\Users\Tom
λ ptpython
>>> class Selfless:
...     def __init__(self, data):
...         self.data = data
...
...     def selfless(self, arg1, arg2):
...         return arg1 + arg2
...
...     def normal(self, arg1, arg2):
...         return self.data + arg1 + arg2

>>> # use Class
>>> obj = Selfless(2)
>>> obj.selfless(5, 8)
13
>>> obj.normal(5, 8)
15
>>>

Not using self in selfless,use @staticmethod.
Then just a function placed in class Selfless

@staticmethod
def selfless(arg1, arg2):
    return arg1 + arg2

@snippsat
Thanks. But i should appreciate explanations about "History", and "Meta+Enter -Execute" Is somewhere a User Help ?

[snippsat]

Press F3 to start history.

I cannot copy correctly a console program. First I tried "double click", on forum's page, 2. I I swept all lines, one after the other; Always same bad copy. Here is the copy:

Error:

You have not started ptpython.
Now you have just coped into command line.
There is always >>> when you start.

E:\1py_div\a
λ ptpython
>>>  

Now first can you copy in code or push F3 for historie as my laste post was about.

Before pasting i got: Warning! Pasting long text (208 chars) may make the console non-responsive until the paste finishes ! Continue ?

Of course I continued , and here is always the same bad copy:

Copy code from my post and it should work.
This can happens when you copy for some other editors,
just try again with different approach.

[sylas]

Strange enough! I went to your post. I tried to copy(1 double clic, then 2 line after line) always the same bad copy. Is it possible nobody until now tried to copy a console program ??

self is always lowercase.

Formally, you can write it the way you want - or replace with any other name, since self is just a convention. Of course, that would be a very bad idea , and it will piss off any Pythonista reading that blasphemy - but it will work
