# Chapter 7 — Strings and Files (Working With Real Data)
This chapter is written as “tiny recipes”.
## 7.1 Strings: Most Used Operations
```python
text = "meetcode python"
print(text.upper())
print(text.split())
print(text.replace("python", "practice"))
```
## 7.2 Reading a Text File
```python
path = "data.txt"
with open(path, "r", encoding="utf-8") as f:
data = f.read()
print(data)
```
## 7.3 Writing a Text File
```python
path = "data.txt"
with open(path, "w", encoding="utf-8") as f:
f.write("Hello from meetcoden")
```
### Diagram: Why `with` Is Good
```text
open file -> do work -> close file
with open(...) does this closing automatically,
even if an error happens inside the block.
```
