How do I create a multiline Python string with inline variables?

Question

I am looking for a clean way to use variables within a multiline Python string. Say I wanted to do the following:

string1 = go
string2 = now
string3 = great

You can use Python 3.6's f-strings for variables inside multi-line or lengthy single-line strings. You can manually specify newline characters using \n.

Variables in a multi-line string

string1 = "go"
string2 = "now"
string3 = "great"

multiline_string = (f"I will {string1} there\n"
                    f"I will go {string2}.\n"
                    f"{string3}.")

print(multiline_string)

I will go there
I will go now
great

Variables in a lengthy single-line string

string1 = "go"
string2 = "now"
string3 = "great"

singleline_string = (f"I will {string1} there. "
                     f"I will go {string2}. "
                     f"{string3}.")

print(singleline_string)

I will go there. I will go now. great.

Alternatively, you can also create a multiline f-string with triple quotes.

multiline_string = f"""I will {string1} there.
I will go {string2}.
{string3}."""
