# Strings
|
|
|
|
Half of what programs do is move text around. Reading user input,
|
|
formatting reports, parsing log lines, validating passwords — all
|
|
strings. This module hands you the toolkit.
|
|
|
|
Seven blocks. About three and a half hours. No conditionals or loops
|
|
yet — those come next module — so every challenge here works through
|
|
indexing, slicing, methods, and built-in functions.
|
|
|
|
## What You'll Do
|
|
|
|
- Index and slice strings
|
|
- Apply the most-used string methods (`upper`, `strip`, `split`,
|
|
`replace`, ...)
|
|
- Validate, count, mirror, and format text
|
|
- Build a small mission report from raw fields
|
|
|
|
## Pace
|
|
|
|
About 3.5 hours. Each block is a small real program — no drills.
