2. 第一个输入参数不同 eval 是 evaluate 的英文简写,只能用来计算单独一个 Python 表达式(expression)的值,返回值是这个表达式的执行结果;在 Python 中,表达式(expression)定义为可以在变量赋值中,进行赋值的对象: #An expression in Python is whatever you can have as the value in a variable assignment:a_...
Hints: dynamic execution of statements is supported by theexec()function. Theglobals()andlocals()functions returns the current global and local dictionary, respectively, which may be useful to pass around for use byeval()orexec(). Seeast.literal_eval()for a function that can safely evaluate s...

Visual Studio provides a comprehensive debugging experience for Python. In this article, you explore how to attach the debugger to running processes and evaluate expressions in the Watch and Immediate windows. In the debugger, you can inspect local variables, use breakpoints, step in/out/over state...
英文文档: eval(expression,globals=None,locals=None)The arguments are a string and optional globals and locals. If provided,globalsmust be a dictionary. If provided,localscan be any mapping object.T…
上下文管理器对象存在以控制with语句,就像迭代器存在以控制for语句一样。 with语句旨在简化一些常见的try/finally用法,它保证在代码块结束后执行某些操作,即使代码块由return、异常或sys.exit()调用终止。finally子句中的代码通常释放关键资源或恢复一些临时更改的先前状态。
你可能会猜到,eval是“evaluate(求值)”的缩写。在这种形式中,用户键入的文本被求值为一个表达式,以产生存储到变量中的值。举例来说,字符串“32”就变成数字32。如果回头看看示例程序,到目前为止,你会看到几个例子,我们像这样从用户那里得到了数字。 x = eval(input("Please enter a number between 0 and 1:...
config.json 用于评估的配置文件的副本。 evaluate_parameters.json 用于计算的参数。 config.json非常相似,但包括其他元数据,如时间戳。 eval_results.jsonl 每个问题和答案,以及每个 QA 对的 GPT 指标。 summary.json 总体结果,如 GPT 平均指标。使用弱提示运行第二次评估编辑...

However, C/C++ debugging and mixed-mode debugging are fully supported in Shell with source code, stepping into native code, and C++ expression evaluation in debugger windows. When you view Python objects in the Locals and Watch debugger tool windows, the mixed-mode debugger shows only the ...
