The check output of a flower shop report with a cdn piece put in twice
Predict the output · Challenge · §10.5 Reviewing the report
The code makes a report file from a weekly sales line chart and a bar chart of totals for a flower shop, then reads the saved file back to check it. Predict the four lines of output without running the code.
Code
from pathlib import Path
import pandas as pd
import plotly.express as px
shop = pd.DataFrame({
"week": [1, 2, 3, 4] * 2,
"flower": ["Roses"] * 4 + ["Tulips"] * 4,
"bunches": [30, 42, 38, 51, 25, 20, 33, 29],
})
weekly = px.line(shop, x="week", y="bunches", color="flower", title="Bunches sold per week")
total = px.bar(shop.groupby("flower", as_index=False)["bunches"].sum(), x="flower", y="bunches",
title="Total bunches")
parts = [weekly.to_html(full_html=False, include_plotlyjs="cdn"),
total.to_html(full_html=False, include_plotlyjs=False)]
path = Path("flowers.html")
path.write_text(f"<h1>Flower shop</h1>\n{parts[0]}\n<h2>Total</h2>\n{parts[0]}\n", encoding="utf-8")
html_text = path.read_text(encoding="utf-8")
print(html_text.count('class="plotly-graph-div"'))
print(html_text.count("plotly.js v"))
print(html_text.count(" src="))
print(sum(len(t.x) for t in weekly.data))Solve this problem in your browser
