Because the regular expression means “match an angle-bracket character,

your string does not match that pattern.

On your first question, make sure you have the right version of Tcl/Tk for your

And what have you found as you've started writing those scripts
int('blah') is not a type error because the int() function is expecting to be
given a string, and it was given a string. The 'blah' is of the correct type.
The problem is that int() couldn't do anything useful with the value of that
string.

I think you're confusing mutating the tuples with assigning the immutable
tuples different names. The variable names are just labels you attach
For example, making

Although it is probably too obvious to be the answer you're looking for, why
can't you just add them in order in the source code?
This way, you can arrange them however you want them to appear, instead of
python arbitrarily enforcing its own order. Python likes being explicit about
things like
ight. Although Java here doesn't necessarily mean the JVM is running
on the embedded machine; it could be Java source code compiled down to

It seems like the ideal case would be to run a remote desktop session
