本指南详细介绍了如何在 VEXcode IQ（第二代）中使用 Python 方法。您将学习如何阅读和理解每种方法，并了解其详尽的描述、参数和使用示例。

了解方法条目#

API 参考中的每个方法条目都包含以下组件：

Command Name – The official name of the command.
Description – A brief explanation of what the command does and what it may return.
Definition – The syntax of the command, showing how it should be written in code.
Parameter Table – Lists all inputs the command accepts.
Example Code – A usage example provided as a copy-and-paste code block.

drive moves the drivetrain in a specified direction indefinitely.

Usage:
drivetrain.drive(direction, velocity, units)

参数	描述
`direction`	The direction in which to drive: `FORWARD` `REVERSE`
`velocity`	Optional. The velocity at which the drivetrain will move as a float or integer. If the velocity is not specified, the default velocity is 50%.
`units`	Optional. The unit that represents the velocity: `PERCENT` `RPM` (Rotations per minute) `VelocityUnits.DPS` (Degrees per second)

参数

描述

direction

The direction in which to drive:

velocity

Optional. The velocity at which the drivetrain will move as a float or integer. If the velocity is not specified, the default velocity is 50%.

units

Optional. The unit that represents the velocity:

# Drive forward then stop
drivetrain.drive(FORWARD)
wait(2, SECONDS)
drivetrain.stop()

# Drive slowly in reverse then stop
drivetrain.drive(REVERSE, 20, PERCENT)
wait(2, SECONDS)
drivetrain.stop()
