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。
PythonTips Don't use a for loop like this for multiple Lists in Python: a=[1,2,3]b=["one","two","three"]# ❌ Don'tforiinrange(len(a)):print(a[i],b[i]) Instead use the handyzip()function: # ✅ Doforval1,val2inzip(a,b):print(val1,val2) ...
Python中的zip函数并不是一个英文单词的缩写,而是直接来源于常见的"zipper"(拉链)因其功能类似拉链将两个列表相互"拉合"。zip函数可以用来将多个可迭代对象(如列表、元组等)的对应元素打包成一个个元组,然后返回由这些元组组成的列表(在Python 3.x中为迭代器)。这个过程类似于拉链的封合过程,每一对相对应的元素...

In Python, the built-in function zip() aggregates the elements from multiple iterable objects (lists, tuples, etc.). It is used when iterating multiple list elements in a for loop. Built-in Functions - zip() — Python 3.8.5 documentation ...
In this step-by-step tutorial, you'll learn what Python Zip applications are and how to create them quickly using the zipapp module from the standard library. You'll also learn some alternative tools you can use to build this kind of application manually
Example for the Zip AppendNew Function top AppendNewDir ZipEntryAppendNewDir(string dirName) Adds an entry to the zip so that when it unzips, a new directory (with no files) is created. The directory does not need to exist on the local filesystem when calling this method. ThedirNameis ...
Python is one of my favourite languages. One of the features it has is the zip function, which allows for parallel iteration of arrays and I wondered if something like that was possible in C++. While I haven't seen anything like this before and I didn't really go to the trouble of re...
