for i,j in zip(num,str): print(i,"is",j) #output: 1 is one 2 is two 3 is three 小葵花课堂又补充知识啦! 内置函数zip()解析: 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列表。 #语法结构: zip([iterable, ...])#iterabl -- 一...
(one=1, two=2, three=3) >>> b = {'one': 1, 'two': 2, 'three': 3} >>> c = dict(zip(['one', 'two', 'three'], [1, 2, 3])) >>> d = dict([('two', 2), ('one', 1), ('three', 3)]) >>> e = dict({'three': 3, 'one': 1, 'two': 2}) >>> ...
在Python中,你可以使用zip方法将两个list组装成一个dict,其中一个list的值作为KEY,另外一个list的值作为VALUE: >>> given = ['John', 'Eric', 'Terry', 'Michael'] >>> family = ['Cleese', 'Idle', 'Gilliam', 'Palin'] >>> pythons = dict(zip(given, family)) >>> print pythons {'John'...
zip将列表、元组或其他序列的元素配对,新建一个元组构成的列表: In[89]:seq1=['foo','bar','baz'] In[90]:seq2=['one','two','three'] In[91]:zipped=zip(seq1,seq2) In[92]:list(zipped) Out[92]:[('foo','one'),('bar','two'),('baz','three')] zip可以处理任意长度的序列,它...
Take another look at the function as it currently stands. Pay particular attention to the three strings in this code, which are all colored green by IDLE: Understanding the string quote characters In Python, strings can be enclosed in a single quote character ('), a double quote character (...
26、zip()、tuple()、dict()、translate()、eval() characters = ('S', 'M', 'E', 'D', 'O', 'N', 'R', 'Y') guess = ('1', '2', '0', '3', '4', '5', '6', '7') tuple(zip(characters, guess)) (('S', '1'), ('M', '2'), ('E', '0'), ('D', '...
The first argument of zip should be the one with fewest elements.▶ Loop variables leaking out!1.for x in range(7): if x == 6: print(x, ': for x inside loop') print(x, ': x in global')Output:6 : for x inside loop 6 : x in global But...
翻看文档，官方是这样明确划分的——有三种基本的序列类型：列表、元组和范围（range）对象。（There are three basic sequence types: lists, tuples, and range objects.）这我倒一直没注意，原来 range 类型居然跟列表和元组是一样地位的基础序列！我一直记挂着字符串是不可变的序列类型，不曾想，...
disk data. If 'infer' and`filepath_or_buffer` is path-like, then detect compression from thefollowing extensions: '.gz', '.bz2', '.zip', or '.xz' (otherwise nodecompression). If using 'zip', the ZIP file must contain only one datafile to be read in. Set to None for no ...
Using the built-in function map, with a first argument of None, you can iterate on both lists in parallel: print "Map:" for x, y in map(None, a, b): print x, y The loop runs three times. On the last iteration, y will be None. Using the built-in function zip also lets ...
