+变量和函数名：使用小写字母，单词之间使用下划线（snake_case）进行分隔。例如：my_variable, calculate_result。 + +常量：使用全大写字母，单词之间使用下划线进行分隔。例如：MAX_VALUE, PI。 + +类名：使用驼峰命名法（CamelCase），即首字母大写，不使用下划线。例如：MyClass, Calculator。 + +模块名：使用小写字母，单词之间使用下划线进行分隔。例如：my_module, utils。 + +- 首先是做好程序的优化，即做好程序函数的封装。 每个函数的函数名尽可能符合文档的编程任务及其要求--要让读者看到函数名就能想到编程任务，这样会更易于理解。 + +- 函数调用关系图的理解是正确的，就是要有一张全局关系图。 + +- 正确理解X1、X2、X3、X4和X5。通常，X1仅是围绕数据结构赋值，和界面或者界面元素坐标无关。X2是依据数据结构中的数据做输出，通常是仅输出。X3通常可以定义函数，或者定义类及其中的函数。X4是在X2基础上做界面交互元素，同时将界面交互元素相关的事件/消息绑定X3或X5的函数。X5也是一些函数。这样界面逻辑和业务逻辑是完全分离的。 + +- 注意：自前向后，编程是越来越复杂，但不要用后面的编程直接替代前面的编程任务中的程序，前面是简单的后面是复杂的。例如“Select Sno from Student”,这是前面的编程，Select :attr1 from :table1"，尽管将attr1赋值成Sno，将table1赋值成Student,也能实现前面的语句，但不可用后面的替换前面的。 + + +### 函数调用关系图： + +函数调用图（Function Call Graph）是用于描述程序中函数之间调用关系的图形表示。它展示了函数之间的依赖关系和调用流程，帮助我们理解程序的执行流程和函数之间的交互 + +在函数调用图中，函数被表示为节点，函数之间的调用关系被表示为边。每个函数调用都会生成一个新的节点和一条连接调用者和被调用者的边。函数调用图可以是有向图或无向图，具体取决于函数调用的方向性。 + +调用图可以用软件生成。 + +![img.png](img.png) + +### 项目文件应包含(后续规范) +项目应该包含以下基本文件： + +1. README.md：项目的说明文档，包含项目的介绍、使用方法、安装指南、贡献指南等重要信息。README.md通常是其他开发者了解和使用项目的入口。 + +2. LICENSE：项目的开源许可证，明确了项目的使用条件和权利限制。选择适合项目的开源许可证对于保护项目的权益和推动开源合作非常重要。 + +3. .gitignore：Git版本控制系统的忽略文件配置，用于指定哪些文件或目录应该被忽略，不纳入版本控制。通常包括一些编译生成的文件、临时文件、敏感信息等。 + +4. requirements.txt：项目的依赖项清单，列出了项目所需的外部库、框架和工具的版本信息。这样其他开发者可以方便地安装相同的依赖项，确保项目的可重复性和一致性。 + +5. setup.py 或者 setup.cfg：用于打包和发布项目的配置文件。可以定义项目的元数据、依赖关系、安装过程等，以便其他人能够方便地安装和使用项目。 + +6. docs 目录：包含项目的文档，例如用户手册、API文档、开发者指南等。良好的文档对于其他开发者和用户理解和使用项目非常重要。 + +7. tests 目录：包含项目的测试代码和测试数据，用于验证项目的正确性和稳定性。包括单元测试、集成测试等，帮助开发者确保项目的质量和可靠性。 + +8. src 或者 lib 目录：包含项目的源代码文件。根据项目的规模和结构，可以进一步组织成子目录或包，方便代码的组织和维护。 + +除了上述基本文件，根据项目的特点和需求，还可以包含其他文件，如配置文件、示例代码、演示视频等。重要的是根据项目的具体情况进行文件的组织和描述，确保项目的可理解性、可维护性和可扩展性。 + +```bash +# 将输出重定向到文件： +pip freeze >

在计算机网络中，路由器、交换机、集线器和主机是网络中常见的设备，它们之间扮演不同的角色，并负责网络通信的不同方面。 + +- 路由器（SimRouter）：路由器是一个网络设备，用于在不同网络之间进行数据包转发。它通过查看数据包的目标地址，并根据网络中的路由表来确定最佳路径将数据包从源地址发送到目标地址。路由器负责跨越不同的网络，如互联网，将数据包从一个网络转发到另一个网络。 + +- 交换机（SimSwitch）：交换机是一个用于连接多个设备的网络设备。它在局域网（LAN）中起到数据包转发和交换的作用。当一个数据包从一个端口进入交换机时，交换机会检查数据包的目标MAC地址，并将其转发到相应的目标端口，以便将数据包传递给正确的目标设备。交换机通过建立MAC地址表来维护设备的连接关系，以便快速转发数据包。 + +- 集线器（SimHub）：集线器是一种被动的网络设备，用于将多个设备连接在一起形成局域网（LAN）。当一个数据包到达集线器时，它会被广播到所有连接的设备，无论数据包的目标地址是什么。这会导致网络中的所有设备都会接收到数据包，但只有目标设备会处理该数据包。因此，集线器的性能较低，并且在现代网络中很少使用。 + +- 主机（SimHost）：主机是指连接到网络的计算机或其他设备。主机可以是个人电脑、服务器、移动设备等。主机可以通过路由器、交换机或集线器与其他设备进行通信。在网络中，主机可以发送和接收数据包，可以是数据的源或目标。 + +### 关于它们之间的通信方式： +- 路由器在不同网络之间进行通信，通过查找路由表将数据包从一个网络转发到另一个网络。它使用IP地址来寻址和路由数据包。

+#### 补充 + +1. TCP/IP协议栈：TCP/IP协议栈是互联网通信所使用的基本协议集合。它由多个协议组成，其中最常用的是TCP（传输控制协议）和IP（互联网协议）。TCP负责可靠的数据传输，而IP则负责将数据包从源主机传送到目标主机。 +2. 以太网：以太网是一种局域网技术，用于在局域网内传输数据。它使用物理介质（如电缆）来连接多台计算机和网络设备。以太网使用MAC地址（媒体访问控制地址）来唯一标识每个网络接口。 +3. IP地址分配：IP地址是在互联网中用于标识网络设备的唯一地址。IP地址分为IPv4和IPv6两个版本。IPv4由32位二进制数组成，通常以点分十进制表示（例如，192.168.0.1）。IPv6由128位二进制数组成，以冒号分隔的八组十六进制数表示。 +4. MAC地址表：MAC地址表是交换机使用的表格，记录了与交换机连接的设备的MAC地址和对应的接口。当交换机接收到一个数据帧时，它会查找目标MAC地址，并将数据帧只发送到目标设备所连接的接口，而不是广播到所有接口上。 +5. 路由表：路由器使用路由表来确定数据包的最佳路径。路由表中包含了目的网络的IP地址范围和下一跳的路由器的IP地址。路由器将数据包转发到适当的下一跳路由器，直到达到目标网络。 +6. 集线器：集线器是一种物理层设备，用于将多个以太网设备连接在一起。当集线器接收到一个数据帧时，它会将数据帧广播到所有连接的设备，这种广播方式会导致网络拥塞和冲突。 +7. 交换机：交换机是一种数据链路层设备，用于连接多个以太网设备，并根据MAC地址表将数据帧只发送到目标设备所连接的接口。交换机提供了更高的带宽和更低的延迟，因为它只将数据发送到目标设备，而不是广播。 +8. 路由器：路由器是一种网络层设备，用于在不同的网络之间转发数据包。路由器使用路由表决定数据包的下一个跳，并负责在网络之间转发数据。路由器能够实现不同网络之间的互联和广域网的连接。 \ No newline at end of file diff --git a/network.db b/network.db new file mode 100644 index 0000000000000000000000000000000000000000..aeddd48499609fe6399120eab8f4c53ca762740a GIT binary patch literal 40960 zcmeI5TWlOx8Gz@qw^?U*N=q;)O+9In#%?<4oHO^*OEw$FvEz7CJ4;)YV$Zd8o7k!2 z779E-nqJ_6mvT{&sDuOp2}I!mwE`pr5(Oa;;!;#0@lcA8Kmt?{5+We@&+N|bxQ^@T z=Augc6U93_bNGZYSoE>i*A6Jey4or_L3+dqnMH#Is%0kP3 zVDjLC@`$$*-0!W7n%bD6%(RXxGwtc=8@mOLKYA)!P!^X~N8v0xp&T4P)M!tyEj8`= z(TTn$nrPan@LikhyL*!&&E=(d@xJEr%1RWhzH!-Ovy(>~vv(^;#_v`}yHy@js$(~m zOT*3WJh!+MMjtr+&N#hx>xz=^@W7>nUNmrV0meYooBDb^{m<9 zlr`I*Uko#hOf!R9Nq9H&RVyjHwqB|Fq-Mp86{Mmbw z8m=rqyc(^{uiG!It!cJcT3ZOhHI?nu^}GSGv>ZnBi}C3vvF`-fg|l>2U%z99;uFLAcUs%&HggR_!IA3fpB-J^!yprh&I^D3e7ltc+`*h>#Wcy48V$$a6dp3TZr_-c> z*Y_HBW&sA>eu-TDhE3{u`5YUOs`9z|&+CuZZ?65N_PN>}HEzrETOQnU?a&{Fo*7yg z+Eab0`mySy^dIRv(ubrQDz8<(R9UL*D*vSXSoui#%F=I2pD!(zwBkRD-z`2_oGETC z{I>9g!ij<*o)f<>eq5Xtw+XKZUlvXYHveD#Mg9|fo8Qj;p8F~@oo};lt?Xz^HQ443 zw+waeaQgr;V%K*a&ruy+w^bwZsp^}0pgP30EMl58GN^qE$nk6CY{QQYYFetRJ47`C z5b-riRV~!R*wSpxrdq*z_j-dgpqlAvzG_)CPz_Tjs$&L$>V}aUTg0+rkJ>j6YS3M8 zkQk=r`UX)=H-Z`(R-`&E302GWj1cyWh#0mrs6l%`gVvx1%>fM>gBsKaG)MN}ds<%({5UtcioPPqgvweM*vn8#D=#=czYX&yOyZ{N{WE}x?} z3}|p{K!f&ZUoa(;&(l49PgB8MXs#dB;O+qp?i$qK&H)WxH>klK>kS5RI<_*X!IAX_jmY&JpE{~-g}!Q7p{=^U9;q6!H9sIQhP%PU zwanmF*r3bnoy%IDpb^_~-6l^Iz! zA=HbBwvX(i`*iDQqY1Y|nggY}M{Z{C4qsE*nL5}$Krg^U`(2=^dj;=liYT$nnCL2j zE2nD223);;-B)Q~XrAYVHlf<#t1p@h+s@;HK_bJ|BTXfd4=#AX%Y}-oHVv#WFal4v zjMh6VBW-EV@KwWecTOh5Gxe$En-Ec|6#!C$dXef84G252W0BA|;~*d|-A613_`;dP z%coaq`g;2?DCBD+a66MKgqsmBw%kay9nE7m7mn%%Uaa~K2@DE10ik1xbMIeV4elrN z`t9%NDVS|Rvw)U73WQVvo!ZJ2>|`FK3P=!WR^%J1=~*!Ztf8rXY+LZwG0eaT0@HGY zex2xSGH<2x^tQJ%JV|Y4TYx90GpR3R>Z*({UHMRpbd4CQ9_S(5`M8Gagf@6($C2ko zUJ%$c;|uBdLgwkQD_KWKnhNd_S-`d~u&wO3u|C?lg-kVursio*?5Qq{CUEN+d2rY1 zxiGf4zU73T7u!U%ujmOTh?zfm1cf6q6YRGQ6CAj4tU3ddxSupmUN4T+GET6V2PfP? zTV-ksb0Vn`=mBj2Bu|afXoE2-jW#kd#2o94nW?UU#>`fgg>4cl9WoahDO1wgIEK(0 zm{_ZlaqeP-@l-kETt{J^7RYq6UK7yC5_7H_pcmGfQ^ky19aRG}n<(@mBMo(uCo+WW zm6YvIiM?>`DazwjKU{kQ5;-I=UENE3ryu2V>h(SybXXwhBgdOu20MmZZx_VA(CE%2wa3<(k3>0yo>$2yp=?2 zNB{{S0VIF~kN^@u0!RP}AOR$R1l~FXtU{qJjlH?={@~`9{$lroDxFG=~fCP{L5To3VR5+^D}?2dW|$ERmE*m^0-(-l3=%yJZM#`h&!bIGk;r(;)n!K z*T4e;@Dx@}U?+QzFx2=?+3wQ=Y=OU${B=(Lw){8wMfp|vC3u4y5(<%>SjjxP$M{|0^|dgzwG& zi^<8}{9mZ8ng7@1QLa>fsvzGhKP~^b{=NEB^}oX*+>ihgKmter2_OL^fCP{L5i;LCW*QyU1q1{Hxr*V5X`S%WX*p!90txHiTQaKk8+WV5ah{jmu`$ z+&}mSpwcE2syLw)`yPd5KHZSQ0;#SG3&(4)COgq$C$=LejBPe+=kMk3Gx)SpdDhHi zGj{%2?wl!r)G+v$XW7C+vIZdEqzTtmunl z!fV0{!bgM&LFRwWKg&nFy1wm?BzbMNjzB`BG%Zb@c1bcgqzfC;GjO z*3WYC59PA_!TK*?7dIq;1dsp{Kmter2_OL^fCP{L5G+d-z?y+Q{?W zditRdO*7h4$Y{@Iv{Y|^HogX1=Q;U2-}VZv+bbho7Y?^*vTojmc>$oV>w1wYe4Qgl t_Jc`2`C@v55~l8`Zs5hL?~uTtzCl9AJpZ@c_HC6NJ#*a^19N>l`9BYH6fXb( literal 0 HcmV?d00001 diff --git a/tkTest.py b/tkTest.py new file mode 100644 index 0000000..8cd1853 --- /dev/null +++ b/tkTest.py @@ -0,0 +1,19 @@ +from tkinter import * +import platform + + +def get_platform(): + import platform + sys_platform = platform.platform().lower() + if "windows" in sys_platform: + print("Windows") + elif "macos" in sys_platform: + print("Mac os") + elif "linux" in sys_platform: + print("Linux") + else: + print("其他系统") + + +if __name__ == "__main__": + get_platform()
