Sns tick_label query

hi
just a quick question about setting the x -axis clicks. For World Cup football project, using csv file and plotting the graph we get world cup years as 1930, 1934 as x -axis clicks… how to change these to: '30, '34 instead. Do I need to use ‘list comprehension’ techniques. Please advise.

thanks…

There may be overlap of centuries, do we really want to use abbreviated years?
