How much do you trust the person creating that template? If it's you
yourself, then probably the easiest way is to use the inbuilt
str.format() method or %-formatting:

template = """Today is: %(date)s
Test ran on %(version)s, in %(time)f seconds."""

data = {"date":"2014-01-07", "version":"v3.4.0b2", "time":123.45}

print(template % data)

Today is: 2014-01-07
Test ran on v3.4.0b2, in 123.450000 seconds.

This gives you a lot of flexibility, as you can lay things out tidily
as well as simply substituting in values.
