Hi, i have 2 lists list1 = {1 2 3 4 5} list2 = {6 7 8 9 }

i want to merge two lists to a new list which gives a result {1 2 6 3 4 7 5 8 9} it will take 2 element from list1 then 1 element from list2 and when condition finish it will print as it is shown in the above example.

please write a generic code.

Let's move this to TCL programs for beginners after you read it, not very concise but it could be a good basic example:

 set result {}
 set list1 {1 2 3 4 5}
 set list2 {6 7 8 9}
 foreach {eL1a eL1b} $list1 eL2 $list2 {
    if {[info exists eL1a] && $eL1a != ""} {lappend result $eL1a}
    if {[info exists eL1b] && $eL1b != ""} {lappend result $eL1b}
    if {[info exists eL2]  && $eL2  != ""} {lappend result $eL2}
 }
 puts $result

or

set list1 {1 2 3 4 5}
set list2 {6 7 8 9}
set result [concat {*}[lmap {a b} $list1 c $list2 {
    concat {*}[list $a $b $c]
}]]

or

set result {}
set list1 {1 2 3 4 5}
set list2 {6 7 8 9}
foreach {a b} $list1 c $list2 {
    lappend result $a $b $c
}
set result [lmap item $result {
    if {$item ne {}} {
        set item
    } else {
        continue
    }
}]
