Returns an iterator of tuples, where thei-th tuple contains thei-th element from each of the argument sequences or iterables. The iterator stops when the shortest input iterable is exhausted. With a single iterable argument, it returns an iterator of 1-tuples. With no arguments, it return...

Python文档研读系列:zip函数 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 arguments whi...
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。
https://www.programiz.com/python-programming/methods/built-in/zip zip() 函数用于将可迭代的对象作为参数,将对象中对应的元素打包成一个个元组,然后返回由这些元组组成的对象。注意:在 Python 2.x zip() 返回的是一个列表。 我们直接通过上面的网址中的案例大致的了解一下zip函数的作用: ...
filterfunc, if given, must be a function taking a single string argument. It will be passed each path (including each individual full file path) before it is added to the archive. If filterfunc returns a false value, the path will not be added, and if it is a directory its contents ...
这是Python 3.10 版本正式采纳的第一个 PEP,「Python猫」一直有跟进社区最新动态的习惯,所以翻译了出来给大家尝鲜,强烈推荐一读。(PS:严格来说,zip() 是一个内置类(built-in type),而不是一个内置函数(built-in function),但我们一般都称它为一个内置函数。) ...
