# String Methods — Python Fundamentals: From Basics to Async

Source: https://www.skillbyai.com/en/python/py-string-methods

> Clean and search text with immutable string methods such as strip, upper, replace and find.

## Everyday methods

Case, whitespace and search helpers cover most everyday text cleanup.

```python
s = "  Hello Python  "
print(s.strip())
print(s.upper())
print(s.lower().strip().startswith("hello"))
print(s.replace("Python", "World"))
```

## Strings are immutable

Every string method returns a **new** string — the original never changes. That's what "immutable" means.
