If satement in one line with 2 variables

Question

How can you put this if satement in a single line?

if long_old != long_new:
      long = 'yes'
      counter_changes +=1

I’ve tried something like this:

long, counter_changes = ('yes',counter_changes +=1) if long_old != long_new

Syntax error…

You could do:

if long_old != long_new: long = 'yes'; counter_changes += 1

By putting a semicolon between the two statements, python lets you put them on one line. (However, this isn’t recommended.)

You could also do:

long, counter_changes = ("yes", counter_changes + 1) if long_old != new_old else (long, counter_changes)

Which sets long and counter_changes to "yes" and counter_changes + 1 if the condition is true, but otherwise sets them to their previous values.

However, if long doesn’t exist, you could just set it to another default value, such as an empty string:

long, counter_changes = ("yes", counter_changes + 1) if long_old != new_old else ("", counter_changes)
