Project 36: Typing Speed Lab ⌨️

Difficulty: 🟡 Intermediate

Run cells top to bottom. Each step builds on the previous one and saves real files under outputs/typing_speed_lab/.

Description

Estimate typing WPM from sample prompts, score accuracy, and chart attempt history.

Libraries & Modules

• time (simulated durations)
• matplotlib

Python Concepts You'll Practice

Metrics (WPM), list history, charting progress

🎛️ Parameter Variations

• PROMPTS
• Simulated SECONDS per attempt

OUTPUT_DIR = Path("outputs") / "typing_speed_lab"
OUTPUT_DIR.mkdir(parents=True, exist_ok=True)
print(f"✅ Outputs folder: {OUTPUT_DIR.resolve()}")

Step 1 — Score attempts

# 🎛️ TWEAK THESE (simulated timings so notebooks stay non-interactive)
PROMPTS = [
    "python loves clean loops",
    "codeitall makes learning playful",
    "functions are reusable spells",
]
SECONDS = [4.2, 5.1, 3.8]  # pretend you typed each prompt in this many seconds

def wpm(text, seconds):
    words = len(text.split())
    return words / (seconds / 60)

attempts = []
for text, sec in zip(PROMPTS, SECONDS):
    attempts.append({"text": text, "seconds": sec, "wpm": wpm(text, sec), "chars": len(text)})
for a in attempts:
    print(f"{a['wpm']:.1f} WPM in {a['seconds']}s — {a['text']}")

57.1 WPM in 4.2s — python loves clean loops
47.1 WPM in 5.1s — codeitall makes learning playful
63.2 WPM in 3.8s — functions are reusable spells

Step 2 — Progress chart

import matplotlib.pyplot as plt

xs = [f"Try {i+1}" for i in range(len(attempts))]
ys = [a["wpm"] for a in attempts]
fig, ax = plt.subplots(figsize=(7, 4))
ax.plot(xs, ys, marker="o", color="#111111", linewidth=2)
ax.set_ylabel("WPM")
ax.set_title("Typing Speed Lab — CodeItAll")
ax.set_ylim(0, max(ys) * 1.3)
fig.tight_layout()
out = OUTPUT_DIR / "typing_speed.png"
fig.savefig(out, dpi=140)
plt.show()
(OUTPUT_DIR / "typing_log.txt").write_text(
    "\n".join(f"{a['wpm']:.1f}|{a['seconds']}|{a['text']}" for a in attempts),
    encoding="utf-8",
)
print(f"Saved {out}")
