⑴ 树莓派系统怎么运行py文件
一、首先写个简单的python
脚本
脚本很简单,就是树莓派上一个灯闪烁程序
文件保存在/home/pi/script/ledblink.py
二
开机启动脚本
保存脚本为/etc/init.d/ledblink文件
三
设置python脚本开机启动
这样就完工了,重启树莓派就会发现led自己闪烁了,停止用sudo
service
ledblink
stop就行
⑵ 已经有树莓派程序,请问如何让程序在树莓派里运行呢
树莓派中sudo是不需要密码的。 所以原则上可以在脚本里切换成ROOT用户。
你这个脚本做什么用,如果只是切换完了,执行一个命令,直接用su就可以搞定,印象中是su -c。su -c USER CMD
如果你想执行完脚本后还保留在root状态中,直接用sudo -s就可以
⑶ 使用PyCharm连接树莓派远程编程
这篇教程是关于如何在Windows操作系统上使用PyCharm IDE远程连接树莓派执行Python 2.7程序。 这篇教程环境是基于运行Windows 10电脑和运行Raspbian OS的树莓派。
第一步 : 确认Windows电脑和树莓派在同一个网络里。
第二步: 在你的Windows电脑上安装PyCharm Professional Edition。
第三步: 必须获取到树莓派的IP地址. 打开树莓派的终端窗口输入以下命令: ifconfig 。
第九步: 配置远程Python Interpreter。
⑷ 树莓派怎么运行程序pathon
前言
Raspbian的系统中包含了Python的编程环境IDE,方便了我们对于python的学习。个人觉得还是游戏程序能够更好的激发我们的潜力所以,话不多说下面就来使用python编写我们简单的游戏程序吧。
储备知识
①import 模块:time时间模块、random随机数模块
②列表:[ ] #[]中放入值,与数组很像,但是不同
③def:定义函数
④python的缩进是编程格式的一种,if等都不需要{}括起来,关键看缩进区分
⑤if,while,def函数都要以 “:”开始
游戏概述
一进入游戏,主人公就会随机获取一个游戏已经设定的道具。最开始,主人公站在丛林的边缘,只有左右可选,左边是个洞穴,右边是沙滩。
选择左边,则开始可以获得手电筒,但是在洞穴中会碰到蛇hp-20,继续向下会到一个未知空间,游戏结束。
选择右边,会到沙滩 获得凉爽的水hp+70,但是由于没有游泳装备,如果继续选择游泳,会遇到海啸而死亡。

return value
else :
print("That is not a recognised answer,must be one of",accepted)

global hp
if location== "start":
print("You are stading on a path at the edge of a jungle.There is a cave to your left and a beach to your right.")
object_.append(random.choice(tools))

return "deep_cave"

#define the function to use the tools of HP
def use_tools(tool):
global hp

for i in range(0,length):
if tool[i]=="50HP":

tool.pop(i)
print("You have use the tool of 50HP")
j+=1
elif tool[i]=="10HP":
hp+=10
tool.pop(i)
print("You have use the tool of 10HP")
j+=1
#The begin of the program.
location = "start"
#Loop until we reach the special "end" location
while location!="end":
location = handle_room(location)
#Check we are not dead each return

if hp<=0:
print("You are dead.\nGame Over!!!")
break
print("Your adventure has ended,bye~")
⑸ 如何通过笔记本电脑远程登录树莓派电脑运行程序
用网线直连电脑,不经过路由器。这个方法最大的特点用最少的工具玩树莓派。
一、材料:树莓派一部、网线一根,笔记本电脑一台。1、树莓派:带供电系统和烧好Raspbian系统的SD卡;2、网线:交叉或直连
