# List

How do you search through a list? Example: look if the value of 25 exists in the list: Listc = [40,30,50,25]

No. Change value in my code, which i posted last,.. And see output. Else part belong to for loop. Not to if block. Lenoname

n = 30 # Is 30 in list? mylist = [10, 20, 40, 30, 50] for val in mylist: if val == n: print(n, "found in list!") break else: print(n, "not found in list.")

Yes. You can Try.. But if if done in a single line, then why need loop!!!

Then go for loop. Internally ' in ' does the same, I think.

[user id=8879050]Per Bratthammar[/user] I just want the ”score” to be printed out, not the rest. b = 4 a = [5,7,8,4,9] for i in a: if i == b: print("Score") break else: print("0 points")

Remove else part. or Lenoname python loop have advantage, to use else with it, executed only when no matching inside.. b = 4 a = [5,7,8,4,9] for i in a: if i == b: print("Score") break else: print("0 points")
