How to add points or markers to line chart using plotly express?

plotly.express is very convenient to produce nice interactive plots. The code below generates a line chart colored by country. Now what I need is to add points to the plot. Does anyone know how I can add points to the line chart?

import plotly.express as px

gapminder = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(gapminder, x="year", y="lifeExp", color='country')
fig.show()

Update:

As of version 5.2.1 you can use markers=True in:

px.line(df, x='year', y='lifeExp', color='country', markers=True)

Previous answer for older versions:

Use fig.update_traces(mode='markers+lines')

Plot:

enter image description here

Code:

import plotly.express as px

gapminder = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(gapminder, x="year", y="lifeExp", color='country')

fig.update_traces(mode='markers+lines')
fig.show()

As of Plotly version 5.2.1 this can now be achieved using the markers argument of px.line. I.e.

import plotly.express as px

gapminder = px.data.gapminder().query("continent=='Oceania'")
fig = px.line(gapminder, x="year", y="lifeExp", color='country', markers=True)
fig.show()
