Python string is not mutable, so you can not use the del statement to remove characters in place. However you can build up a new string while looping through the original one:
def reverse(text):
rev_text = ""
for char in text:
rev_text = char + rev_text
return rev_text
reverse("hello")
# 'olleh'

The problem is that you can't use del on a string in python.
However this code works without del and will hopefully do the trick:
def reverse(text):
a = ""
for i in range(1, len(text) + 1):
a += text[len(text) - i]
return a
print(reverse("Hello World!")) # prints: !dlroW olleH

7 proven methods to reverse the python string in 2021
"".join(sorted(a, reverse=True)) will not reverse a string. >>> a = "hello world" >>> "".join(sorted(a, reverse=True)) 'wroolllhed ' There's a deeper problem with articles like this, though. Reversing a string is a trivial task (i.e., it's something for a beginner to learn). Giving seven different methods with no explanation on if one is better than another is not good teaching, especially when some don't even work and others are pointlessly verbose. More on reddit.com
