zip函数的用法: deffunc_zip(n, m):returnzip(n, m)#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title = ["name","age","gender"] info= ["benben", 18,"女"] res=dict(func_zip(title, info))print(res) res=lambdax, y: zip(x, y)print(dict(res(title, info)))#...
To sort 2 listsxandybyx: new_x, new_y = zip(*sorted(zip(x, y))) Functions used to sort two lists together We can achieve this by using 3 built-in functions:zip(list1, list2),sorted(list)andzip(*list). zip(list1, list2)returns a zip object by pairing the elements at the...
18Prints the maximum of two numbers. 19The two values must be integers. 在函数的第一个逻辑行的字符串是这个函数的 文档字符串 。注意,DocStrings也适用于模块和 类
The built-in function zip takes two lists and returns list of pairs.>>> zip(["a", "b", "c"], [1, 2, 3]) [('a', 1), ('b', 2), ('c', 3)] It is handy when we want to iterate over two lists together.names = ["a", "b", "c"] values = [1, 2, 3] for ...

Sort thepressurearray into lists of blood pressure readings for smokers and non-smokers. Python list comprehensions provide a compact method for iterating over sequences. With the Pythonzipfunction, you can iterate over multiple sequences in a singleforloop. ...
Here the interpreter isn't smart enough while executing y = 257 to recognize that we've already created an integer of the value 257, and so it goes on to create another object in the memory.Similar optimization applies to other immutable objects like empty tuples as well. Since lists are...
参数v的可能取值为*lists,也就是 tuple 的一个元素。 lambda函数返回值,等于lambda v冒号后表达式的返回值。 四、 数据结构 29 转为字典 创建数据字典 In [1]: dict() Out[1]: {} In [2]: dict(a='a',b='b') Out[2]: {'a': 'a', 'b': 'b'} In [3]: dict(zip(['a','b'],[...
