The zip() function takes a number ofiterablesand aggregates them to a single one by combining thei-thvalues of each iterable into a tuple. For example, zip together lists [1, 2, 3] and [4, 5, 6] to [(1,4), (2,5), (3,6)]. You can unzip this list of tuples by calling...
列表用方括号括起来,用单引号将字符串值括起来 | jolly_list = [ 1,2,3,4,5 ]happy_list = [ 'Hello ',123,' Orange' ] | |元组| 与列表不同,元组是只读的,不能动态更新。元组用括号括起来 | 体面元组= ( 1,2,3)amazing_tuple = ( 1.12,“Ok”,456.5) | |设置| 集合是使用花括号初始化...
You can also provide your own list of tuples as indices. For example, x = model.addVars([(3,'a'), (3,'b'), (7,'b'), (7,'c')]) would be accessed in the same way as the previous example (x[3,'a'], x[7,'c'], etc.), except that not all combinations will be pres...
You use zip() to unzip the content of sales into two variables: x holds a list of fruits. y holds the corresponding units sold per fruit. Then you create a bar chart using plt.bar(). When you run plt.show(), you get a window like the following on your screen: In this chart...
tuple([iterable]) Rather than being a function, tuple is actually an immutable sequence type, as documented in Tuples and Sequence Types — list, tuple, range.class type(object) class type(name, bases, dict) With one argument, return the type of an object. The return value is a type ...
