另外,在exec中是可以赋值的,基本等同于js的eval。 >>> c = 'b=78+45' >>> exec(c) >>> b 123 也可以定义函数: >>> c = """def func(a):print(a)""" >>> exec(c) >>> func <function func at 0x0000002D3656D6A8> >>> func(5) 5 >>> 1.3. complie函数 compile(source, filena...
Note:If you are passing the name of a function to theEvalfunction, you must include parentheses after the name of the function in thestringexprargument. For example: ' ShowNames is user-defined function. Debug.Print Eval("ShowNames()") ...

如果找到相应匹配,则替换其别名定义,并退回第一步;否则进入第4步。该策略允许递归别名,还允许定义关键字别名。如alias procedure=function 4、执行大括号扩展,例如a{b,c}变成ab ac 5、如果~位于单词开头,用$HOME替换~。 使用usr的主目录替换~user。
