llength not returning correct list size

问题

I have a list which has the elements below.

test = {a[1] b[60] c[25] c[36]}

I am checking the length of test as below:

set result [llength ($test)]

This is giving me the error below:

list element in braces followed by ")" instead of space

What could be the issue?

Thanks in advance.

回答1:

You might need to review the basics of Tcl syntax

Don't put parenthesis around the argument to llength.

set x {test = {a[1] b[60] c[25] c[36]}}
set result [llength $x]

In future questions, it is better to post an entire program that can be executed so that your error can be reproduced easily.
