Today we will look closely in. Series.map () : Map values of Series using input correspondence (which can be a dict, Series, or function) Series.apply () Invoke function on values of Series. The apply () method is defined for Series as well as Dataframes. It works with a function, series, or dictionary as its input argument. The map () method is defined only for Series objects.<\/strong><\/p>\n<p><figure> \t\t<img decoding=\"async\" src=\"https:\/\/www.researchgate.net\/profile\/Oliver-Eboy\/publication\/334169807\/figure\/tbl1\/AS:776206945382404@1562073565907\/Comparison-of-paper-mapping-and-digital-mapping_Q640.jpg\" alt=\"Comparison of paper mapping and digital mapping | Download Scientific ...\" style=\"width: 100%; padding: 5px; background-color: grey;\"><figcaption>Comparison of paper mapping and digital mapping | Download Scientific &#8230; (Ophelia Patrick)<\/figcaption><\/figure>\n<p> \t \t<strong>Map Vs Apply<\/strong>. <strong>I like the following method: Trace shows you every detail of every step of a calculation; if you apply Trace to each of your calculations, you&#39;ll see that there are simply more steps required for some methods than the others.
