pyhton list x = [ ] vs mylist x = [ ]

Both commands are wrong. You simply create new list like this:

x = []

Select allOpen in new window

You can alternatively use

x = list()

Select allOpen in new window

but it is not prefered when creating the empty list.

The reason why the list is highlighted is that it is a built-in type in Python (one of the most frequently used containers, used as a list, as a stack, as a queue, as an array). You can try in the interactive mode (wrapped lines by the console):

>>> x = list()

The mylist is just some identifier. But in Python, you do not tell the data type when creating a variable. Variables are not bound to any type. They are just names given to references. The reference values are not bound to the target type either. They are untyped.

Ok, sorry for my typo.

So list and mylist are same in this context. Right?

MvH.

Yes. They are both wrong in the context. Syntax highlighting in editors just highlights certain character sequences. It knows the list, and it does not know the mylist. This is the only reason for the different colours.

Ok, don't get mad.

list = [ ]  and mylist = [ ] are same. Right?

Hey, this was my 1000. question in EE. :)

Good questions are often better than good answers. The questions make us thinking. When the question is not known, the anwer cannot be found. Also, we often ignore the answers if we do not understand the questions. :)
