List

Question

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

Answer 1

No. Change value in my code, which i posted last,.. And see output.

Else part belong to for loop. Not to if block. Lenoname

Answer 2

# Hi! You use ’in’:
print(25 in Listc)

Use "in" keyword

Answer 5

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.")

Answer 6

Can i do it with a loop?

Answer 7

Jayakrishna🇮🇳 Because the chapter i’m at still hasn’t introduced ”in” yet.

Answer 8

Yes, I already, updated on that doubt.
See code again..
change input and try again code.

Answer 9

Jayakrishna🇮🇳 like this?i changed b on purpose, gives no output
b = 70
a = [5,7,8,4,9]
for i in a:
if i == b:
print("Score")
break

print("0 points")

Answer 10

listc=[40,30,50,25]
Print(listc[3])

Answer 11

if any(list(map(lambda x: True if x==25 else False, Listc))):
print(True )

Answer 12

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

Answer 13

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

Answer 14

Jayakrishna🇮🇳 almost zero idea how

Answer 15

Lenoname You have now code already..,

Answer 16

Per Bratthammar 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")

Answer 17

Says
0 point
0 point
0 point
Score

Answer 18

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")

Answer 19

Jayakrishna🇮🇳 and if it doesnt find 25 in the list?(lets say its not there) i want it to say ”0 point”
