ExampleGet your own Python Server Join two tuples together: a = ("John","Charles","Mike") b = ("Jenny","Christy","Monica") x =zip(a, b) Try it Yourself » Definition and Usage Thezip()function returns a zip object, which is an iterator of tuples where the first item in eac...
7 如果我们可以将zip对象转为list后的列表展开，实际上得到了元素交替合并的列表。这一展开函数为itertools.chain.from_iterable。因为某些原因，python中没有展开任意层的函数。这一问题有人讨论：Why doesn't Python have a "flatten" function for lists.注意事项 如果遇到问题，可以在下面提出疑问。
一,函数的文档: zip(): Make an iterator that aggregates elements from each of the iterables. Returns an iterator of tuples, where the i-th tuple contains the
map(function, sequence[, sequence, ...]) -> list 通过定义可以看到,这个函数的第一个参数是一个函数,剩下的参数是一个或多个序列,返回值是一个集合。 function可以理解为是一个一对一或多对一函数,map的作用是以参数序列中的每一个元素调用function函数,返回包含每次function函数返回值的list。
1---zip function created by me. itisstuip---2[('name','victor'), ('sex','male'), ('age','18')]3---standard zip function---4[('name','victor'), ('sex','male'), ('age','18')] zip函数在我实际工作中用的最多就是从数据库中拿到数据之后,把这些数据组成一个dict的list。
This function returns a list of tuples, where the i-th tuple contains the i-th element from each of the argument sequences or iterables. The returned list is truncated in length to the length of the shortest argument sequence. When there are multiple ...
After we take a look at docs of itertools.tee function, there is Python recipe that with some modification can help in our case def transpose_finite_iterables(iterable): iterator = iter(iterable) try: first_elements = next(iterator) except StopIteration: return () queues = [deque([element]...
zip()函数与Python中的for循环一起使用的可视化 在应用for循环后注意缺少的元素!Python的另一个很棒的功能——列表推导式,可以与zip()函数结合使用。表面上看起来很简单…… m=["mind","mouse","mini"]n=["norm","night","necklace"][print(a,b)fora,binzip(m,n)] ...
