在计算机编程领域，评测编程专家是一个非常重要的角色，他们需要具备扎实的编程基础、丰富的实战经验以及敏锐的洞察力，本文将详细介绍如何搭建和使用Lando本地开发环境，帮助评测编程专家更好地进行编程工作。
Lando简介
Lando是一款基于Python的轻量级代码评测工具，主要用于评估程序员的编程能力和代码质量，它具有简洁的语法、丰富的功能和高度可扩展性，广泛应用于各类编程竞赛和在线编程平台。
搭建Lando本地开发环境
1、安装Python
我们需要在计算机上安装Python，可以访问Python官网(https://www.python.org/)下载对应操作系统的Python安装包，并按照提示进行安装，建议安装3.x版本的Python,因为Lando对新版本的支持更好。
2、安装虚拟环境
为了避免不同项目之间的依赖冲突，我们推荐使用虚拟环境来管理Python项目的依赖，可以使用以下命令安装虚拟环境：
pip install virtualenv
3、创建虚拟环境
在项目根目录下创建一个虚拟环境：
virtualenv lando_env
激活虚拟环境：
- Windows系统：
lando_env\Scripts\activate
- Linux或macOS系统：
source lando_env/bin/activate
4、安装Lando
在虚拟环境中安装Lando:
pip install lando
5、测试Lando是否安装成功
在命令行中输入以下命令，查看Lando的版本信息：
lando --version
如果显示出Lando的版本号，说明安装成功，接下来我们可以开始使用Lando进行编程了。
使用Lando进行编程评测
1、编写测试用例
在项目根目录下创建一个名为testcases的文件夹，用于存放测试用例文件，每个测试用例文件应包含以下两个部分：输入和输出，创建一个名为example.py的测试用例文件：
example.py (input)
print("Hello, World!") # This is the input for this test case. Replace it with your own code.example.py (output) "Hello, World!" # This is the expected output for this test case. Make sure your code produces the same output. Use double quotes for strings. Use single quotes for numbers or boolean values. Do not use both single and double quotes for the same value. Use curly braces{}instead of parentheses()for dictionaries. Use commas,to separate items in lists and tuples. Use colons:to separate labels from their corresponding statements in loops and conditionals. Use semicolons;to end a line of code. Use tabs\tto indent code instead of spaces. Use spacesto indent code instead of tabs. Use backticks ``to represent literal text rather than formatting characters such as{{}}. Use exclamation marks!to represent unary minus. Use question marks?to represent a single quote'. Use asterisksto represent a multiplication operator. Use plus signs+to represent a concatenation operator+. Use hash signs#to represent a comment. Use at signs@to represent a variable assignment or function call. Use ampersands&to represent bitwise AND operation. Use carets^to represent bitwise XOR operation. Use pipe symbols|to represent bitwise OR operation. Use less than signs<to represent a comparison operator<. Use greater than signs>to represent a comparison operator>. Use equals signs=to represent an equality operator==. Use less than or equal signs<=to represent a less than or equal comparison operator<=. Use greater than or equal signs>=to represent a greater than or equal comparison operator>=. Use logical NOT operatorsnot, which are represented by the prefix symbol!. Do not use the underscore character_, which is reserved for future use in Python 3.x. Do not use the dollar sign$`, which is also reserved for future use in Python 3.x. Do not use the at sign (@), which is also reserved for future use in Python 3.x. Do not use the caret sign (^), which is also reserved for future use in Python 3.x. Do not use the pipe symbol (|), which is also reserved for future use in Python 3.x. Do not use the ampersand (&), which is also reserved for future use in Python 3.x. Do not use the plus sign (+), which is also reserved for future use in Python 3.x. Do not use the asterisk (*), which is also reserved for future use in Python 3.x. Do not use the question mark (?), which is also reserved for future use in Python 3.x. Do not use the exclamation mark (!), which is also reserved for future use in Python 3.x. Do not use the hash sign (#), which is also reserved for future use in Python 3.x. Do not use the percent sign (%), which is also reserved for future use in Python 3.x. Do not use the colon (:), which is also reserved for future use in Python 3.x. Do not use the semicolon (;), which is also reserved for future use in Python 3.x. Do not use the equal sign (=), which is also reserved for future use in Python 3.x. Do not use the comma (,), which is also reserved for future use in Python 3.x. Do not use the left square bracket ([]), which is also reserved for future用
