我正在建一個鬧鐘項目。誰能告訴我如何編寫一個腳本來調用所有其他腳本嗎。例如，我在我的樹莓派上有三個腳本叫做LCDTESTFORPI.py，另一個叫做“ex 7”分段.py“還有一個叫”報警pi.py”. 我希望能夠運行一個名為“alarmpi”的腳本_初始py“它將運行所有其他腳本，然后可以設置為在啟動時運行。我知道有可能我就是不知道怎么寫。

以前，有人建議我應該使用正確的格式，把所有這些都放在一個腳本的函數中，但我不知道怎么做。

以下是所述代碼的副本：

# 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，我無法打開另外兩個代碼文件，因為一個是.config文件，另一個當前正在美國不同地區的設備上運行。但是顯示的兩個代碼文件是我在這篇文章中要處理的兩個。
