Its basic use case is to draw Markdown-formatted text, whenever the\ninput is a string:

\n
\nwrite('Hello, *World!* :sunglasses:')\n
\n\n \n \n (view standalone Streamlit app)\n \n

As mentioned earlier, st.write() also accepts other data formats, such as\nnumbers, data frames, styled data frames, and assorted objects:

\n
\nst.write(1234)\nst.write(pd.DataFrame({\n    'first column': [1, 2, 3, 4],\n    'second column': [10, 20, 30, 40],\n}))\n
\n\n \n \n (view standalone Streamlit app)\n \n

Finally, you can pass in multiple arguments to do things like:

\n
\nst.write('1 + 1 = ', 2)\nst.write('Below is a DataFrame:', data_frame, 'Above is a dataframe.')\n
\n\n \n \n (view standalone Streamlit app)\n \n

Oh, one more thing: st.write accepts chart objects too! For example:

\n
\nimport pandas as pd\nimport numpy as np\nimport altair as alt\n\ndf = pd.DataFrame(\n    np.random.randn(200, 3),\n    columns=['a', 'b', 'c'])\n\nc = alt.Chart(df).mark_circle().encode(\n    x='a', y='b', size='c', color='c', tooltip=['a', 'b', 'c'])\n\nst.write(c)\n

Matplotlib supports several types of "backends". If you're getting an\nerror using Matplotlib with Streamlit, try setting your backend to "TkAgg":

\n
\necho "backend: TkAgg" >> ~/.matplotlib/matplotlibrc\n

\n

Its basic use case is to draw Markdown-formatted text, whenever the\ninput is a string:

\n
\nwrite('Hello, *World!* :sunglasses:')\n
\n\n \n \n (view standalone Streamlit app)\n \n

As mentioned earlier, st.write() also accepts other data formats, such as\nnumbers, data frames, styled data frames, and assorted objects:

\n
\nst.write(1234)\nst.write(pd.DataFrame({\n    'first column': [1, 2, 3, 4],\n    'second column': [10, 20, 30, 40],\n}))\n
\n\n \n \n (view standalone Streamlit app)\n \n

Finally, you can pass in multiple arguments to do things like:

\n
\nst.write('1 + 1 = ', 2)\nst.write('Below is a DataFrame:', data_frame, 'Above is a dataframe.')\n
\n\n \n \n (view standalone Streamlit app)\n \n

Oh, one more thing: st.write accepts chart objects too! For example:

\n
\nimport pandas as pd\nimport numpy as np\nimport altair as alt\n\ndf = pd.DataFrame(\n    np.random.randn(200, 3),\n    columns=['a', 'b', 'c'])\n\nc = alt.Chart(df).mark_circle().encode(\n    x='a', y='b', size='c', color='c', tooltip=['a', 'b', 'c'])\n\nst.write(c)\n
\n\n \n \n (view standalone Streamlit app)\n \n

Write arguments to the app.

This is the Swiss Army knife of Streamlit commands: it does different\nthings depending on what you throw at it. Unlike other Streamlit commands,\nwrite() has some unique properties:

\n
    \n
  1. You can pass in multiple arguments, all of which will be written.
    2. \n
  2. Its behavior depends on the input types as follows.
    3. \n
  3. It returns None, so its "slot" in the App cannot be reused.
    4. \n

One or many objects to print to the App.

Arguments are handled as follows:

\n
    \n
  • \n
    write(string) : Prints the formatted Markdown string, with
    \n
    support for LaTeX expression, emoji shortcodes, and colored text.\nSee docs for st.markdown for more.
    \n
    \n
    • \n
  • write(data_frame) : Displays the DataFrame as a table.
    • \n
  • write(error) : Prints an exception specially.
    • \n
  • write(func) : Displays information about a function.
    • \n
  • write(module) : Displays information about the module.
    • \n
  • write(dict) : Displays dict in an interactive widget.
    • \n
  • write(mpl_fig) : Displays a Matplotlib figure.
    • \n
  • write(altair) : Displays an Altair chart.
    • \n
  • write(keras) : Displays a Keras model.
    • \n
  • write(graphviz) : Displays a Graphviz graph.
    • \n
  • write(plotly_fig) : Displays a Plotly figure.
    • \n
  • write(bokeh_fig) : Displays a Bokeh figure.
    • \n
  • write(sympy_expr) : Prints SymPy expression using LaTeX.
    • \n
  • write(htmlable) : Prints _repr_html_() for the object if available.
    • \n
  • write(obj) : Prints str(obj) if otherwise unknown.
    • \n

This is a keyword-only argument that defaults to False.

\n

By default, any HTML tags found in strings will be escaped and\ntherefore treated as pure text. This behavior may be turned off by\nsetting this argument to True.

\n

That said, we strongly advise against it. It is hard to write secure\nHTML, so by using this argument you may be compromising your users'\nsecurity. For more information, see:
