i want an output like if I entered a name "hello"

then the output should be as follows:-
olleh
olle
oll
ol

What I have tried:

m= input("Enter name: ")
n=len(m)
for i in range(n+1):
print([n+1:i-1:1])

I know that as a learner my code is wrong

Look at what you are supposed to print:
First line 5 characters
Second line 4 characters
...
Last line 1 character

So you just need to print the first N characters of the word each time, counting down from the word length to 1.

See 3. An Informal Introduction to Python — Python 3.11.0 documentation[^] for how to extract parts of a string.

Well, first, you're going to have to reverse your string, which you are not doing.

Next, you have to create a range that goes from n to 0. What would be the stop value for that?

After that, you need to print a substring of you string. THe code doesn't work because you didn't tell the print statement what string to print. What variable is holding your string?

And lastly, you need to rethink how you'e specifying the substring to print, specifically, what values/variables are going in the [::] substring spec. Hint: You only need to specify one value. I leave it to you to figure out which position between the brackets and colons.

Well, you got the range wrong, and you're really not thinking about the substring arguments. WRite your "Hello" on paper and go through the code, step by step, keeping track of variables on paper. This should make it a lot easier to figure out.

Your best source is going to be books on Python. DO NOT USE YOUTUBE "TUTORIALS"!
