I'm a great scripter, but just learning programming (using Python).
I'm very much a newbie at this, so please be patient as I'm sure these will seem so basic a questions and may seem stupid to those experienced.
I'm reading a python book right now that has me thinking about variables.
As the title says, what does "x=5" really mean?
What is the "5" being assigned to? Is "x" considered an "instance" of "int?"
If I do this:
Then x here is an instance of class test(), a subclass of int.
But with int, you can do x=5.
If I do that after the above code, then x is no longer an instance of test() but is a variable of type int().
In the above, what is the 5 actually being assigned to in the instance of test()?
I have accessed it by defining a class and doing this just messing around:
Why doesn't the value of x change to 6 in the above example? I'm I "redefining" self in the value() method to no longer reflect what is self in the instance?
Also, can I "hijack" what x=5 means to to add my own methods, but it still behave like x=5. What I mean might be explained by this code:
Or something like that?
If there is no way to do that and we go back to my original subclass definition, how do I change the value of the instance of the class to another value?
In:
How does the value of x become incremented internally? What magic is happening behind the scenes?
Say I want to do what is verboten in Python. Make in C-like incrementor like this.
So that I could do something like this:
Helping me with the concepts would really go a long way for me. Any help would be greatly appreciated.
Hi Friends,
Can any of you explain me about the below line of code?
mn_code=`env|grep "..mn"|awk -F"=" '{print $2}'`
Im not able to understand, what exactly it is doing :confused:
Any help would be useful for me.
