I'm new to python programming language and recently I've just encountered this problem and I really want to know how to solve it

so here's the input:

list = ["Sam-11,Mark-10,Mike-14","Martha-12,Emma-9,Kyla-13"]

the output should be like this:

Mark-10, Emma-9

// Prints the names with the least age in the two strings inside the list including their age

    try and find some tutorials on list manipulation. you'll probably find some useful list methods you can use to sort elements. – L_Church Apr 10 '18 at 15:28

    Off the point but I'm really confused about what this list is meant to represent. Would you prefer a dictionary for this instead of a list? A dictionary is basically a key:value pair where a key is linked to a value. So you can have "Mark" linked to the value of 10 – L_Church Apr 10 '18 at 15:31
  • The first string represents boys and their age then the second string represents girls and their age. – Max Ager Apr 10 '18 at 15:33
  • ok. First, you need to put the code you are using. after that, we can help you to figure out a solution. – Kenry Sanchez Apr 10 '18 at 15:34

  • a nested dictionary then could be key:boys with a value of a dictionary with all the boys then another key:girls with a value of a dictionary with all the girls. so many possibilites lol. – L_Church Apr 10 '18 at 15:36

It is a straight forward solution :

print(", ".join( [ min(each_element.split(","),key = lambda x:int(x.split("-")[1])) for each_element in list_obj ] ))

you split each element on the comma and then find max of the resultant list based on the secondary parameter then you join it as you want.

    That is not straight forward in the eyes of a new developer... baha – L_Church Apr 10 '18 at 15:33

    Also the answer is wrong. This prints `"Mike-14, Emma-9"` not "`Mark-10, Emma-9"`. This is because you are using `max` when you should be using `min` and you are doing a lexicographical sort instead of integer sort. – pault Apr 10 '18 at 15:38
  • Thank you Pault, I didnt notice , that he had asked for a minimum, and yes, thank you for pointing out my mistakes. – Kenstars Apr 10 '18 at 15:43
  • Now it works, but I would not say it's straightforward- clearly you had trouble with it yourself. You could improve this answer with a more detailed explanation for beginners. Also that line is too long, IMO. – pault Apr 10 '18 at 15:44
  • your code works thank you so much ... now I'm trying to figure out the logic behind it for the future sml – Max Ager Apr 10 '18 at 17:27
