tcl Dictionaries Iterating over a dictionary
Example
You can iterate over the contents of a dictionary with dict for, which is similar to foreach:
set theDict {abcd {ab cd} bcde {ef gh} cdef {ij kl}}
dict for {theKey theValue} $theDict {
puts "$theKey -> $theValue"
}
This produces this output:
abcd -> ab cd bcde -> ef gh cdef -> ij kl
You'd get the same output by using dict keys to list the keys and iterating over that:
foreach theKey [dict keys $theDict] {
set theValue [dict get $theDict $theKey]
puts "$theKey -> $theValue"
}
But dict for is more efficient.
