What is the purpose of the two colons in this Python string-slicing statement?

If i had a list as an example:
a = ['Hello_1.txt', 'Hello_2.txt']
In Python is it possible to somehow remove the first 5 characters ('Hello')
and the last 3 characters ('txt') from each of the items in the list ?
You could use a list-comprehension and string slicing:
[s[5:-3] for s in a]
which gives what you describe (not sure this is the neatest output though!)
['_1.', '_2.']

In Python how can I need to create a long list that I'm trying to avoid typing, the list looks lis this
brands = ['_1','_2','_3'... '_998']
I can create the list of numbers with a for loop, but I'm trying to use list comprehension for the characters which should be faster.
Thanks!
my list=["_" + str(i) for i in range(1,999)]

I need to insert a '*' between each two characters in a string in Python, for example, for 'ABCDE' I need to get 'A*B*C*D*E'. What's a Python way of doing it?
This could be a solution
string ='ABCDE'
x = '*'
print(x.join(string))

How do I split a list into equally-sized chunks?
(66 answers)
Closed 3 years ago.
So I have string like this:
"UFFKTEWKW"
And I need to convert it to a list or tuple like this:
("UFF", "KTE", "WKW")
So every 3 letters from the string goes to separate element of list or tuple.
I can't use split() here because string doesn't have any delimiters. I don't wanna make some dummy for cycle for it. And I think there should be simple solution for it.
You can use this.
a="UFFKTEWKW"
out=tuple(a[i:i+3] for i in range(0,len(a),3))
# ('UFF', 'KTE', 'WKW')

Hello I am learning PYTHON and was learning about string splitting .so I have a hex string named
A="aca80202"
I want to convert it into a list of 2 characters
B=["ac","a8","02",02"]
is there any way to do it?
If you are starting with Python you could do it in a simple way using a for loop:
A="aca80202"
B = []
for i in range(0, len(A), 2):
B.append(A[i:i+2])
EDIT: you could see more ways to do it here.

In Python: How do I write a function that would remove "x" number of characters from the beginning of a string?
For instance if my string was "gorilla" and I want to be able remove two letters it would then return "rilla".
OR if my string was "table" and I wanted to remove the first three letters it would return "le".
Please help and thank you everyone!
You can use this syntax called slices
s = 'gorilla'
s[2:]
will return
'rilla'
