if you create csvs with python then you probably often need to write headers with those csvs for instance if you need to use the csv with pandas or import it into sql once youamp;#39;ve created it then headers are obviously the way to identify and how do you best create header if you start appending to your code within a for loop you donamp;#39;t want to have headers each time this is where iamp;#39;m about to show you how to use if not header added which looks to see if youamp;#39;ve already got a header and if you already have then donamp;#39;t write a new one so letamp;#39;s get going with some code okay so this is an example where iamp;#39;m writing a header line here and then iamp;#39;m writing the content which is an f string based upon these variables um the key point here is that weamp;#39;re doing it with without using csv writer import csv and also weamp;#39;re doing it within a for loop so if i just quickly run it and iamp;#39;ll show you what the problem
