我正在建一个闹钟项目。谁能告诉我如何编写一个脚本来调用所有其他脚本吗。例如，我在我的树莓派上有三个脚本叫做LCDTESTFORPI.py，另一个叫做“ex 7”分段.py“还有一个叫”报警pi.py”. 我希望能够运行一个名为“alarmpi”的脚本_初始py“它将运行所有其他脚本，然后可以设置为在启动时运行。我知道有可能我就是不知道怎么写。
以前，有人建议我应该使用正确的格式，把所有这些都放在一个脚本的函数中，但我不知道怎么做。
以下是所述代码的副本：

# The wiring for the LCD is as follows:
# 1 : GND
# 2 : 5V
# 3 : Contrast (0-5V)*
# 4 : RS (Register Select)
# 5 : R/W (Read Write) - GROUND THIS PIN! We do not want the LCD to send anything to the Pi @ 5v
# 6 : Enable or Strobe
# 7 : Data Bit 0 - NOT USED
# 8 : Data Bit 1 - NOT USED
# 9 : Data Bit 2 - NOT USED
# 10: Data Bit 3 - NOT USED
# 11: Data Bit 4
# 12: Data Bit 5
# 13: Data Bit 6
# 14: Data Bit 7
# 15: LCD Backlight +5V
# 16: LCD Backlight GND (Red)
# 17: LCD Backlight GND (Green)
# 18: LCD Backlight GND (Blue)

不幸的是，我无法打开另外两个代码文件，因为一个是.config文件，另一个当前正在美国不同地区的设备上运行。但是显示的两个代码文件是我在这篇文章中要处理的两个。
