🐹 1. print()函数概述 print()方法用于打印输出,是python中最常见的一个函数。 该函数的语法如下: print(*objects, sep='', end='\n', file=sys.stdout) 参数的具体含义如下: objects--表示输出的对象。输出多个对象时,需要用 , (逗号)分隔。 #【单个对象】#输出数字print(1)#数值类型可以直接输出#...
mylist = ['one', 'two', 'three', 'four', 'five'] mylist[1:3] = ['Hello', 'Guys'] print(mylist)The result will be:['one', 'Hello', 'Guys', 'four', 'five']Insert Into a List/在列表中插入元素You can use the insert method to insert an element to the list like this:...
print(np.subtract(x, y)) # Elementwise product; both produce the array # [[ 5.0 12.0] # [21.0 32.0]] print(x * y) print(np.multiply(x, y)) # Elementwise division; both produce the array # [[ 0.2 0.33333333] # [ 0.42857143 0.5 ]] print(x / y) print(np.divide(x, y)) #...
reversed()和sorted()同样表示对列表/元组进行倒转和排序,reversed()返回一个倒转后的迭代器(上文例子使用list()函数再将其转换为列表);sorted()返回排好序的新列表。 列表和元组存储方式的差异 前面说了,列表和元组最重要的区别就是,列表是动态的、可变的,而元组是静态的、不可变的。这样的差异,势必会影响两者...
