Text Diary.

Ninth class — Text capstone. You combine string cleaning, joining, and counting in a loop.

Typical flow: walk entries, strip() into a clean list, count the rows you care about, build a short f-string message, and print the results.

Mini example:

lines = ["  ok  ", "ok"]
clean = []
for line in lines:
    clean.append(line.strip())
n = 0
for line in clean:
    if line == "ok":
        n = n + 1
print(len(clean))
print("-".join(clean))
print(f"ok: {n}")

This is the spirit of a small diary analyzer: raw lines → clean → count → report. We do not introduce new constructions — only combine what you already learned.
