# llength(n)

Count the number of elements in a list

```

```

## NAME

llength - Count the number of elements in a list

## SYNOPSIS

**llength** *list*

```

```

## DESCRIPTION

Treats *list* as a list and returns a decimal string giving the number of elements in it.

## EXAMPLES

The result is the number of elements:

```
% llength {a b c d e}
5
% llength {a b c}
3
% llength {}
0
```

Elements are not guaranteed to be exactly words in a dictionary sense of course, especially when quoting is used:

```
% llength {a b {c d} e}
4
% llength {a b { } c d e}
6
```

An empty list is not necessarily an empty string:

```
% set var { }; puts "[string length $var],[llength $var]"
1,0
```
