First, use split() to split the input into a list. Then, you need to test isnumeric() on every element of the list, not the whole string. Call int() to convert the list elements to integers. Finally, add the sum to counter, not counter_item. my_list = input(“Input your list.(Numbers)\n”).split() while not all(item.isnumeric() for item in my_list): … Read more
Actually, the function returns a value. Maybe you want to see it, so just print the result: #include <stdio.h> #include <cs50.h> int calcrectarea(int len,int wid){ return len*wid; } int main(){ printf(“enter length here:\n”); int x; scanf(“%d”,&x); printf(“enter width here:\n”); int y; scanf(“%d”, &y); printf(“area is: %d”, calcrectarea(x,y)); } solved The function is not returning in … Read more

Short answer, Yes Running this type of data will out-perform CPU. Long answer, if its is ( stream-able), what I mean is that if you can have your data structured in such a way that its iterable and can be emitted one by one to some consuming end, then yes. But about the programing language … Read more
If you need such sequencing, you might reevaluate your need to use goroutines. However, the way you described the solution is correct: go first() { for { <-ch1 // do stuff ch2<-struct{}{} } }() go second() { for { <-ch2 // do stuff ch3<-struct{}{} } }() go third() { for { <-ch3 // do stuff … Read more

That is because the ternary operator always evaluates to a single type. You can’t “return” different types with this operator. When the compiler encounters such an expression he tries to figure out whether he can reduce the whole thing to one type. If that’s not possible you get a compile error. In your case there … Read more
If you want to check if a string i contains string j, you can do it using i in j. Then comes the part how do you want the output actually. What my approach was to go through the list1 and for each of them go though the list2 and check if element of list2 … Read more
@lily … saw your message before I left. This code will create a file.

Considering what you are doing, won’t using memcached be a better option? You just store your ips as key=value pairs in memcached, with an expiry of 5 minutes. Thus your data always expires every 5 minutes. Also interaction with memcached is much easier than file-handling. 2 solved How to delete a .txt file after a … Read more
Map over the array and assign each key value pair to a new object after converting it to a string. const array = [{abcd:1, cdef:7},{abcd:2, cdef:8}, {abcd:3, cdef:9}]; array.map(el => { const stringObj = {} Object.keys(el).forEach(key => { stringObj[key] = el[key].toString(); }) return stringObj; }) 1 solved transforming elements in array from numbers to string

Depends on why you’re doing what you’re doing with this code. If you’re just trying to golf it, one way to make it shorter is to remove the definitions of the lambdas and call them inline. Something like below var numbers = [0,1,2,3,4,5,6,7,8,9]; var greaterthanvalues = ((numbers, value) => numbers.filter((number) => number > value ))(numbers, … Read more
