Hi,
I just wanna know how to set SYSTEM variables and USER variables of windows,
but got no way.
Firstly I thought "os.environ + os.system" may work well, but found no way
to let "os.environ" run to retrive USER variables.
Then I tried win32api, finding the GetEnvironmentVaria

Hi.
My problem is to replace all occurrences of a sublist with a new element.
Example:
Given ['a','c','a','c','c','g','a','c'] I want to replace all

If Python were statically typed, you might be correct.
A _value_ in python has a type,
