In fact, the builtin "open" function is now called "file"; the name
"open" is there only for backward compatibility.
So the original example:
>>> import os
>>> file = os.open("e:\\d12", "r")
is bad news for two reasons:
1) It uses os.open when it should use the builtin function;
2) It uses a variable named "file", which will step on the
name of the builtin function.
If you write it this way:
# no need to import os here
myfile = file("e:\\d12", "r")
you may find the resulting code easier to understand.
