To create a chart in Python using Bokeh, you need to follow these steps:

1. Install Bokeh library by running "pip install bokeh" in your terminal/command prompt.
2. Import the necessary modules (e.g. bokeh.plotting).
3. Prepare the data that you want to plot.
4. Create a figure object and specify the type of chart you want to create (e.g. line, scatter, bar).
5. Add the data to the figure using the appropriate methods (e.g. line(), scatter(), vbar()).
6. Customize the chart's appearance by setting various attributes (e.g. title, axis labels, grid lines).
7. Show the chart using show() method or save it to an HTML file using save().

Here is an example of a simple line chart in Bokeh:

from bokeh.plotting import figure, show
# Prepare the data
x = [1, 2, 3, 4, 5]
y = [5, 4, 3, 2, 1]

# Create the chart
p = figure(title="Line Chart Example")
p.line(x, y)

# Show the chart
show(p)
