Here we briefly enumerate the features of Vyper language.

Contract members:

• functions
• global variables
• events
• contract interfaces

Types:

• uint256
• decimal
• bytes32
• address
• bool
• unit types
• bytes[n] - variable-size byte arrays
• list
• struct
• tuple
• map

Statements:

• variable declaration: a: int128 or a: int128 = e
• assignment: a = e
• augmented assignment: a += e
• if
• for in range: for i in in range(rounds) or for i in in range(start, end)
• for in list: `for elem in [1, 2, 3]'
• break
• continue
• return
• assert
• throw
• log - event logging
• del - deleting elements from a map
• function calls
• external contract calls

Binary operators: + - * / % ** Unary operators: ! - Boolean operators: and or Comparison operators: < <= > >= == != in
