eval(expression[, globals[, locals]]) execfile(filename[, globals[, locals]]) Help on built-in function execfile in module __builtin__: execfile(...) execfile(filename[, globals[, locals]]) Read and execute a Python script from a file. The globals and locals are dictionaries, defaulti...

如果function为None,将以元素值作为运算结果值进行filter(类似于列表生成式[item for item in iterable if item])。itertools库中的ifilter,ifilterfalse有着类似的作用。 Talk is short, show you the code. >>>l2=filter(None,l1)>>>l2 [1,2,3,4,5]>>>l1=[0,1,2,3,4,5]>>>id(l1)75023688L>...
例如,`vars(locals())`将返回一个包含当前全局变量的字典。 19. `zip(*iterables)`:将多个可迭代对象组合成元组的列表。例如,`zip(range(3), range(3))`将返回[(0, 0), (0, 1), (0, 2), (1, 0), (1, 1), (1, 2)]。 20. `*args`:将可变参数解包为元组。例如,`*args`将解包为...

If the locals dictionary is omitted it defaults to the globals dictionary. If both dictionaries are omitted, the expression is executed in the environment where execfile() is called. The return value is None.Note The default locals act as described for function locals() below: modifications to ...
locals() The locals() function is used to get the local symbol table as a dictionary. Free variables are returned by locals() when it is called in function blocks, but not in class blocks. map() The map() function is used to execute a specified function for each item in a inerrable...
