介绍#

VEXcode IQ(第二代)控制台显示在 VEXcode 的监视器窗口中。控制台方法可以在项目运行时显示文本、数字和变量值。它们还可以清除控制台、读取用户输入以及设置更改颜色后打印文本的颜色。

使用 VS Code 时,基于文本的控制台输出会出现在终端中,而不是 VEXcode 控制台中。

注意: 使用 VEXcode 控制台时,必须先连接到控制台串口,然后才能将任何输出打印到控制台。

以下是所有方法的列表:

操作——输出文本或清空控制台。

  • print — Displays text, numbers, or variable values in the Console or terminal.

  • clear_console — Clears all rows in the Console.

Getter 方法——读取用户输入。

  • input — Displays an optional prompt string, waits for user input, and returns the response as text.

Mutator — 格式化打印文本。

行动#

print#

print displays text, numbers, or variable values in the Console. In VS Code, print displays output in the terminal.

如果您希望打印消息中包含项目中的值(例如分数、计时器或传感器读数),请使用自定义字符串格式。有关更多信息,请参阅字符串格式页面。

By default, each print() statement ends with \n, which stands for a new line. This moves the cursor to the next line after the value is printed. The optional end parameter changes what is added after the printed value.

Usage:
print(value, end=“\n”)

范围

描述

value

要在控制台或终端中显示的文本、数字或变量值。

end

Optional. The text added after value is printed. The default is “\n”, which moves the cursor to the next line. Use end=“” to keep the next printed value immediately after the previous value on the same line. Use another string, such as end=”, “, to add text between printed values.

# Display two messages on separate lines
print("Hello, robot!")
print("This prints on the next line.")

VEXcode 控制台,显示控制台和文本“Hello, robot!”(显示在第一行)以及“This prints on the next line”(显示在其下一行)。

# Display two messages on the same line
print("Hello,", end=" ")
print("robot!")

VEXcode 控制台,显示控制台和文本“Hello, robot!”。

# Print three colors on one line, separated by commas
colors = ["Red", "Green", "Blue"]

for color in colors:
    print(color, end=", ")

VEXcode 控制台,显示控制台和文本“红、绿、蓝”。

转义序列#

Escape sequences are short codes that can be printed with print to change how text appears in the Console.

Most projects should use set_console_text_color to change text color and clear_console to clear the Console. Escape sequences are useful when you want to do those things directly inside a print statement.

To change the text color, print \033 followed by a color code.

# Print VEXcode in red
print("\033[31mVEXcode")

# Set the Console text color to red before printing
print("\033[31m")
print("VEXcode")

To clear the entire Console with an escape sequence, print \033[2J. This also moves the cursor back to row 1.

# Clear the Console after two seconds
print("VEXcode")
wait(2, SECONDS)
print("\033[2J")

clear_console#

clear_console clears all rows from the Console.

Usage:
clear_console()

参数

描述

此方法没有参数。

# Display text, then clear it after two seconds
print("This will disappear...")
wait(2, SECONDS)
clear_console()

Getter#

input#

input displays an optional prompt string, waits for the user to enter a response, then returns that response as text.

The project pauses at input() until a response is entered in the Console. In VS Code, the response is entered in the terminal.

The value returned by input() is always text. To use the response as a number, convert it first with int() or float().

Usage:
input(prompt)

范围

描述

prompt

可选。在等待响应之前,要在控制台或终端中显示的字符串。如果未指定提示符,则在等待之前不显示任何消息。

# Ask for a name, then print a greeting
answer = input("What's your name?")
print("Hello, " + answer)

VEXcode 控制台,显示控制台和文本“你的名字是什么?”,后面跟着“>>VEX”,下方是“你好 VEX”

# Ask for a number, then use it in math
answer = input("Enter a number:")
number = float(answer)
print(number + 1)

VEXcode 控制台,显示控制台和文本“输入一个数字:”,后面跟着“>> 4”,下方是“5.0”

变异体#

set_console_text_color#

set_console_text_color sets the color used for text printed in the Console after this method is used. At the start of a project, the Console text color is set to BLUE.

此方法可更改 VEXcode 控制台中的文本颜色。在 VS Code 中,不同终端对颜色的支持可能有所不同。

Usage:
set_console_text_color(color)

范围

描述

color

The color to use for text printed in the Console:

  • Color.BLACK
  • Color.BLUE
  • Color.CYAN
  • Color.GREEN
  • Color.ORANGE
  • Color.PURPLE
  • Color.RED
  • Color.WHITE
  • Color.YELLOW

# Print text in different colors
print("Default text color")
set_console_text_color(Color.RED)
print("Red text color")

VEXcode 控制台,显示控制台和蓝色文字“默认文本颜色”(第一行),红色文字“红色文本颜色”(第二行)。
