People = [['See', 22], ['Aerry', 35], ['Tonny', 55], ['Nurdin', 22]] print(people) x

Question

People = [['See', 22], ['Aerry', 35], ['Tonny', 55], ['Nurdin', 22]] print(people) x

= min(people, key=lambda x: x[1])
for i in people:
while i[1] == x[1]:
people.remove(i)
print(people)

Why am i getting an error here when i use the while loop? I wanted to remove elements with minimum numbers and for my case its ['Nurdin', 22] and ['See', 22]
I wanted the statement inside while loop to run if any element has number 22 but it decided to bring an error

I don't have any idea how i will use it without for loop. If there is no for loop, then what will i use as i? I mean this i[1]

I meant the while loop, it is unnecessary, what you need is an if statement, not a while

Also, you're trying to modify a list while iterating over it, that's not recommended, as it will bring weird bugs that are harder to find and debug

I don't know why if i use the input function, i don't get the result that i want though. My output was supposed to print the second last minimum persons having minimum number. I expected the output to be : Brian Sii But it gave me Mamma as the output

It's not about being in the middle, it's about printing the second last number so Brian and Sii are having second last number as you can see from that list. Here is the code : people = [] for _ in range(int(input())): people.append([input(), float(input())]) for i in people: x = max(people, key=lambda x: x[1]) if i[1] == x[1]: people.remove(i) for z in people: y = max(people, key=lambda x: x[1]) if z[1] == y[1]: print(z[0])

To post more than a few lines of code, use a pastebin like: * dpaste.org * linkode.org * bin.kv2.dev * hastebin.com If you are stuck in a terminal, you can use ix.io or paste.rs to paste from the CLI: <command to print output> |& curl -F 'f:1=<-' ix.io <command to print output> |& curl --data-binary @- https://paste.rs

Potential points of bugs: 1. Your uncommented code doesn't check for second minimum, but the absolute minimum. The commented code probably does check for the second. 2. You're recalculating x in each iteration, meaning it will change (the minimum will change) as you modify the list. 3. You're modifying the list inside its own iteration, i already said that's a big source of bugs. 4. You're iterating over your modified list, it will certainly be different from your original one, with less items than the ones you inputted.

Tbf I don't understand what you're trying to do in either of the code snippets. If you give us an example with input/output we might provide more insights into a potential pythonic solution

Manipulating source list is usually not recommended. Find the item in the list that match whatever you want, and copy it into new list. With that you can verify that your filtering command is correct

You have an infinite loop in that while. Why do you have it, if you're already iterating with the outer for loop?
