Reverse the content of each element in a list python

Question

I have a list:

lst = ['abcdef', 'uvwxyz']

I want to get as result:

['fedcba', 'zyxwvu']

How can I do that in Python 3 (and Python 2 if it's possible)?

EDIT :

Here i want to Reverse the content of each element in a list !

NOT Reverse the elements in the list !

If i do:

lst[::-1]

I'll get:

['uvwxyz', 'abcdef']

and that's not what i want !

You can index a list or string with a negative step; Python 2 or 3 don't matter here, btw. — , Nov 10 '15 at 21:12
for `python-2.7` i edited my question, and yes i did some research of course, but i just find "Reversing `the elements` in the list", and i want to reverse the `content` of each element. — Bilal, Nov 10 '15 at 21:13

so look up "*python reverse string*". I bet there's a result or 2 for that... — MattDMo, Nov 10 '15 at 21:14

The slice [::-1] means to use the entire list/string etc. and step through with a step of -1.

so:

>>> 'abcdef'[::-1]
'fedcba'

Since you need to do this for each item of a list, a list comprehension is a good solution

>>> lst = ['abcdef', 'uvwxyz']
>>> [x[::-1] for x in lst]
['fedcba', 'zyxwvu']

l=['123','456','789']
l1=[]
for i in l:
    l1.append(int(i[::-1]))
print(l1)

Output:[321, 654, 987]

str1="I am a student from college"
str2=list(str1.split(" "))
print(str2)
reverse=[x[::-1]for x in str2 ]
print(reverse)

That looks like broken syntaxc, but more importantly it looks like no explanation whatsoever. If you add an explanation, I will happily help you with the correct formatting. – Yunnosch Jul 15 '22 at 12:57
