from pydantic import BaseModel

# Объявляем параметр как `str`
# и получаем поддержку редактора кода внутри функции
def main(user_id: str):
    return user_id


# Модель Pydantic
class User(BaseModel):
    id: int
    name: str
    joined: date
```

Это можно использовать так:

```Python
my_user: User = User(id=3, name="John Doe", joined="2018-07-19")

second_user_data = {
    "id": 4,
    "name": "Mary",

		return
	}

	vars := mux.Vars(r)
	v := vars["pool"]
	byID := vars["by-id"] == "true"

	pools := strings.Split(v, ",")
	poolIndices := make([]int, 0, len(pools))

	for _, pool := range pools {
		var idx int
		if byID {
			var err error
			idx, err = strconv.Atoi(pool)
			if err != nil {
				// We didn't find any matching pools, invalid input

# Gradle platform architecture

Gradle is arranged into coarse-grained components called "architecture modules" and "platforms".
See [ADR4](standards/0004-use-a-platform-architecture.md) for a definition of these terms.

The diagram below shows the current set of architecture modules and platforms:
