In Ruby I can do this:
"This is a string with the value of #{variable} shown."
How do I do that same thing in Python?

You have a lot of options.
"This is a string with the value of " + str(variable) + " shown."
"This is a string with the value of %s shown." % (str(variable))
"This is a string with the value of {0} shown.".format(variable)

The modern/preferred way is to use str.format:
"This is a string with the value of {} shown.".format(variable)
Below is a demonstration:
>>> 'abc{}'.format(123)
'abc123'
>>>
Note that in Python versions before 2.7, you need to explicitly number the format fields:
"This is a string with the value of {0} shown.".format(variable)

@C.B.: 2.7 and up, actually.

@MartjinPieters really? I tried that on 2.7 and it threw errors at me. Maybe it was 2.6
this is one of the way we can also do
from string import Template
s = Template('$who likes $what')
s.substitute(who='tim', what='kung pao')

Also good, though possibly overkill for his particular example.
