给定一个切片,我们想得到这个切片的平方,这就是做一些复杂的数学运算,我们可以这样写。 代码语言:javascript 代码运行次数:0 运行 AI代码解释 mathNum:=[...]int{1,2,34,5,6,99}b:=[num*numfornum<-mathNum]println(b) 同样,如果我们想要获得大于某个数的平方,直接加条件即可。 代码语言:java

A generator expression is slightly similar to list comprehension but to get the output of generators expression we have to iterate over it. It is one of the best ways to use less memory for solving the same problem that takes more memory in the list compression. Here, a round bracket is ...
List comprehension and map() are both used to create new lists in Python, but they are used in slightly different ways. List comprehension is a more concise way to create a new list by applying an operation to each element in an existing list. It is written as a single line of code ...
