How to insert a variable in a string that is repeated multiple times in Python

I'm trying to write code efficiently that does something like this:

if (str == "Sunday"):
   return "Today is Sunday. Have a good day."

or

if (str == "Monday")
  return "Today is Saturday. Have a good day."

etc..

Is there a way to set the standard string with a variable {} and then assign the variable later on the script - without having to repeat the string 7 times?

str conflicts with Python's own builtin str function, so I will assume you named the input day instead.

You can do this in several ways:

# concatenate
return "Today is " + day + ". Have a good day"

# f-string
return f"Today is {day}. Have a good day"

# format method (f-string is just alternate syntax for this)
return "Today is {}. Have a good day".format(day)

The common name for this is "string interpolation", so you can search for that to learn more.
