sign(list,'foreach')(property(foreach)) 然后调用本文引言中的方法,将十进制字符串列表转为4位二进制字符串列表: bins=list(['1','2','3','4'].foreach.int().do(lambda_:bin(_)[2:]).do(lambda_:"{:0>4}".format(_)))# ['0001', '0010', '0011', '0100'] 内置类型的方法注册 下...
每次循环时,您指定为的变量都会设置为列表中下一个元素的值。当您看到一个for语句时,可以认为它是“for each element in the list. ” for循环的流程图如图 请注意,您无需使用任何索引即可获取列表中每个元素的值。 for循环会自动为您执行此操作。它负责繁琐的簿记工作。此语法非常优雅和简单。 请注意:for后接...
enumerateworks by supplying a corresponding index to each element in the list that you pass it. Each time you go through the loop,indexwill be one greater, anditemwill be the next item in the sequence. choices = ['pizza','pasta','salad','nachos']print'Your choices are:'forindex, item...
如果EnumerationType 是ElementCollection,则按上文所述设置 OuterXPathStringSourceType 和 OuterXPathString。 然后,单击 InnerElementType 并选择内部元素的枚举类型,然后单击 InnerXPathStringSourceType。 根据为 InnerXPathStringSourceType 设置的值,请选择变量或文件连接,创建新的变量或文件连接,或键入内部 XPath 表达式的...

forEach((element) => { console.log({ element }); numCallbackRuns++; }); console.log({ numCallbackRuns }); // { element: 1 } // { element: 3 } // { element: 7 } // { numCallbackRuns: 3 } 如你所见,不会为索引 2 处的缺失值调用回调函数。
