> [!TLDR]
> Since strings are immutable, "deleting" means building a NEW string that copies every character except the unwanted one — one loop with a simple inequality test.

**Idea.** A Python string cannot be edited in place, so the function creates an empty result string and walks the original once: characters equal to the target are skipped, all others are appended. This removes **all** occurrences, exactly as asked, and the original string remains unchanged — the new string is returned.

```python
def deleteChar(st, ch):
    """Return a new string with all occurrences of ch removed from st."""
    newStr = ""
    for c in st:
        if c != ch:          # keep every character that is NOT ch
            newStr += c
    return newStr

# main program
s = input("Enter a string: ")
c = input("Enter the character to delete: ")
result = deleteChar(s, c)
print("Original string:", s)
print("String after deletion:", result)
```

**Trace** for deleteChar("banana", "a") — watch newStr grow:

| Step | c | c != 'a'? | newStr after step |
|------|---|-----------|-------------------|
| 1 | b | yes — append | b |
| 2 | a | no — skip | b |
| 3 | n | yes — append | bn |
| 4 | a | no — skip | bn |
| 5 | n | yes — append | bnn |
| 6 | a | no — skip | bnn | …
