First, install the `pydantic-settings` package:

<div class="termy">

```console
$ pip install pydantic-settings
---> 100%
```

</div>

It also comes included when you install the `all` extras with:

<div class="termy">

```console
$ pip install "fastapi[all]"
---> 100%
```

</div>

```java
/**

 * <span class="label">Groovy</span>
 * <pre><code class="language-groovy">

 * reportsDir = file('reports')

 * </div>
 */
```

	// riscv64:"MUL\t",-"MULHU"
	_, lo := bits.Mul64(x, y)
	return lo

func Div(hi, lo, x uint) (q, r uint) {
	// amd64:"DIVQ"
	return bits.Div(hi, lo, x)

func Div32(hi, lo, x uint32) (q, r uint32) {

	return bits.Div32(hi, lo, x)

func Div64(hi, lo, x uint64) (q, r uint64) {

## Install `PyJWT`

We need to install `PyJWT` to generate and verify the JWT tokens in Python:

<div class="termy">

```console
$ pip install pyjwt

---> 100%
```

</div>

!!! info
    If you are planning to use digital signature algorithms like RSA or ECDSA, you should install the cryptography library dependency `pyjwt[crypto]`.

    history.pushState('', '', url.toString()); // Makes back-button work
    matches = new Set();
    search.value = '';
    render();
  }

  function handleEnter(box, div) {
    if (actionMenuOn) return;
    const src = stacks.Sources[box.src];
    div.title = details(box) + ' │ ' + src.FullName + (src.Inlined ? "\n(inlined)" : "");
    detailBox.innerText = summary(box.sumpos, box.sumneg);
