description	Mapping standard and common libraries from Python to Scala, including datetime, decimal, and JSON.

Python to Scala Libraries and Specialized Types

This skill covers the translation of library-specific functionality.

Datetime

• Python: datetime.datetime, datetime.date.
• Scala: java.time.LocalDateTime, java.time.LocalDate.
• Formatting: java.time.format.DateTimeFormatter.

Python	Scala
dt.strftime("%Y-%m-%d")	dt.format(DateTimeFormatter.ofPattern("yyyy-MM-dd"))
datetime.now()	LocalDateTime.now()

Decimal

• Python: decimal.Decimal.
• Scala: BigDecimal.
• Formatting: f"$decimal%.2f".

JSON (Circe)

• Python: json.dumps(obj), json.loads(str).
• Scala (Circe): obj.asJson.noSpaces, parse(str).
• Recursive JSON: Use io.circe.Json for a safe representation.

Error Handling

• Python: try...except, raise RuntimeError.
• Scala: Try[T] (Success/Failure), Either[L, R].
• Runtime Error: throw new RuntimeException("...").

import scala.util.Try
val result = Try(operation()) // Success(v) or Failure(e)
