Try This: Condense the Input

Let’s try reducing the input to int line count from six to three.

• Set the cyber:bot board’s PWR switch to 0.
• Use the micro:bit Python Editor to open terminal_controlled_bot_tethered_intro.
• Set the project name to terminal_controlled_bot_tethered_try_this.
• Replace these six lines:

        text = input("Enter left speed: ")
        vL = int(text)

        text = input("Enter right speed: ")
        vR = int(text)

        text = input("Enter ms to run: ")
        ms = int(text)

    …with these three lines:

        vL = int(input("Enter left speed: "))
        vR = int(input("Enter right speed: "))
        ms = int(input("Enter ms to run: "))

• Check your modified script, it should resemble the example below.
• Click Save and Send to micro:bit.
• Repeat the tests you did with terminal_controlled_bot_tethered_intro and verify that this modified version runs the same as the original.  

Example script: terminal_controlled_bot_tethered_try_this

# terminal_controlled_bot_tethered_try_this

from cyberbot import *

sleep(1000)

print("\nSpeeds are -100 to 100\n")

while(True):
    vL = int(input("Enter left speed: "))
    vR = int(input("Enter right speed: "))
    ms = int(input("Enter ms to run: "))

    bot(18).servo_speed(vL)
    bot(19).servo_speed(-vR)
    sleep(ms)
    bot(18).servo_speed(None)
    bot(19).servo_speed(None)

    print()
