# `list` Function
|
|
|
|
-> **Note:** This page is about Terraform 0.12 and later. For Terraform 0.11 and
|
|
earlier, see
|
|
[0.11 Configuration Language: Interpolation Syntax](../../configuration-0-11/interpolation.html).
|
|
|
|
The `list` function is no longer available. Prior to Terraform v0.12 it was
|
|
the only available syntax for writing a literal list inside an expression,
|
|
but Terraform v0.12 introduced a new first-class syntax.
|
|
|
|
To update an expression like `list(a, b, c)`, write the following instead:
|
|
|
|
```
|
|
tolist([a, b, c])
|
|
```
|
|
|
|
The `[ ... ]` brackets construct a tuple value, and then the `tolist` function
|
|
then converts it to a list. For more information on the value types in the
|
|
Terraform language, see [Type Constraints](../types.html).
