'str' object is not an iterator

The error message "str object is not an iterator" suggests that you are trying to iterate over a string as an iterator, but strings in Python are not iterable in the same way as lists or other iterable objects.
To iterate over the characters of a string, you can either convert it into a list and then iterate over the list, or use a loop that directly operates on the string. Here are two examples:
Example 1: Converting string to a list and iterating over it
```python
my_string = "Hello"
my_list = list(my_string)
# Now you can iterate over the list
for character in my_list:
print(character)
```
Example 2: Looping directly over the string
```python
my_string = "Hello"
# Looping over the string
for character in my_string:
print(character)
```
Keep in mind that strings are immutable in Python, so if you need to modify the characters of a string, you will need to create a new string with the desired modifications.
