How do I make a dataframe table to show in html-CodePudding

I have a dataframe like this which I created using the function below in app.py

                 cases    deaths
state                             
New York      1203003648  31391997
California    2188008059  30864267
Texas         1745177048  28252336
Florida       1461739406  22255383
New Jersey     561292201  15263394
Pennsylvania   672001545  14669903

app.py

def find_top_confirmed_states(n = 10):

    df = pd.read_csv('https://raw.githubusercontent.com/nytimes/covid-19-data/master/us-states.csv')
    by_state = df.groupby('state').sum()[['cases', 'deaths']]
    tcs = by_state.nlargest(n, 'deaths')
    return tcs

tcs = find_top_confirmed_states()

@app.route('/')
def Index():
    return render_template("index.html", table=tcs, cmap=html_map, list=tcs.values.tolist())

index.html

                {% for p in list %}
                <tr>
                    <td>{{ p[0]}}</td>
                    <td>{{ p[1]}}</td>
                    <td>{{ p[2]}}</td>
                </tr>
                {% endfor %}

Now I just want to show this table in html

My table is not showing. The best that I could do was to show the number of cases and death, but I can't make the states to show. How do I work with this dataframe that will show in a table in html

CodePudding user response：

Pandas has a built-in DataFrame.to_html(). You can take that text directly and embed it in your website.

https://pandas.pydata.org/pandas-docs/stable/reference/api/pandas.DataFrame.to_html.html

CodePudding user response：

You can use

def Index():
    return df.to_html(header="true", table_id="table")

def Index():
    return render_template('file.html',  tables=[df.to_html(classes='data')], titles=df.columns.values

and html jinja template for above method:

{% for table in tables %}
  {{titles[loop.index]}}
  {{ table|safe }}
{% endfor %}

also is possible to use render_template and remove {{titles[loop.index]}} line

return render_template('file.html',  tables=[df.to_html(classes='data', header="true")])

CodePudding user response：

I solved my problem by adding the following line:

tcs2 = [(state, cases, deaths) for state, cases, deaths in zip(tcs.index, tcs['cases'],tcs['deaths'])]

this generated the following output:

[('New York', 1203003648, 31391997), ('California', 2188008059, 30864267), ('Texas', 1745177048, 28252336),....]

so I sent to my html file using:

@app.route('/')
def Index():
    return render_template("index.html", table=tcs, cmap=html_map, tcs2=tcs2)

So I could just iterate to have my table in my html file using the code that I already had which was:

             {% for p in tcs2 %}
                <tr>
                    <td>{{ p[0]}}</td>
                    <td>{{ p[1]}}</td>
                    <td>{{ p[2]}}</td>
                </tr>
                {% endfor %}
