Help reversing a int list in python

Question

X = input()
Y = X.split()
for i in range(len(y)):
k = [::-1]
k[i]= int(k[i])
print(k)

Prints the list converts it to int but doesn’t reverse it help

Answer 1

Whenever the user inputs the number via input() it will be a ***string***, not an integer in a list.

Observe the difference, when you put:

x = '12345' # input()
y = [int(i) for i in x]
print(y[::-1])

If you need help, you need to give the complete task description (+ course name).

Answer 2

3 options of many here

x = input().split() # makes your list
y = [int(i) for i in x]
print(y[::-1])

#or

b = []
for i in x:
b.append(int(i))
print(b[::-1])

#or

c = []
for i in range(len(x),0,-1):
c.append(i)
print(c)

Try separating your numbers with a space, else the code reads it as a single number

Good suggestion, else we gonna capsize soon. 🤣😂

Answer 5

I sure hope not Rik 😁

Answer 6

For this <X> input

"12 23 34 45 56"

Is the result supposed to be like this?

[ 56, 45, 34, 23, 12 ]

Or this?

[ 21, 32, 43, 54, 65 ]

Or this?

[ 65, 54, 43, 32, 21 ]

Or something else?

How are you inputting your numbers.

if you put them in as: 1 2 3 4 5, then the codes will work.

if you input as 1,2,3,4,5, then you will need x = input.split(',')

Let me know how you go, if you still can't get it, then I will write an example for you

Answer 8

X33X,
Better post a link to the code in progress, so we can all stay in the same boat.

Answer 9

Thanks that totally fixed it lol guess we didnt need to convert the str to a list first

Answer 10

You can use the reverse() method on the list.

Answer 11

I tried the reverse method on my code i still got the exact same input in int mot reversed

For the X input the result should be a reversed list of the input e.g [1,2,3,4] = [4,3,2,1]

And i tried all three options

x = input().split() # makes your list
y = [int(i) for i in x]
print(y[::-1])

Output = the same input unreversed e.g [1,2] is still [1,2]

b = []
for i in x:
b.append(int(i))
print(b[::-1])

Output= no output.

or

c = []
for i in range(len(x),0,-1):
c.append(i)
print(c)

Output = e.g input = [1,2,3] it prints [‘123’, 1]

None worked dont know whats wrong

Answer 12

My input is 12345 i didn’t separate my input with commas

Answer 14

Putting spaces in between the number works but the project sepcifies the user input all number without spaces its the credit card validator on sololearn

It should read it all as a str first the we can reverse the str and turn that into an int (that was my idea)

Answer 15

y should be of the same case eg both should either be of capital leter or small letter and not mixing

Answer 16

Do nothing ; just “list_name.reverse”

Answer 17

X =[1,2,3,5,3 8,4]
Print(X.reverse())
