You can check if a column exists in a PySpark DataFrame using theschemaattribute, which contains the DataFrame’s schema information. By examining the schema, you can verify the presence of a column by checking for its name. Theschemaattribute provides aStructTypeobject, which contains a list of...
In this third example, we will use Python’s built-incount()function, along with the“if”and“else”statement, to check whether a fruit string exists within the list: ifmyFruits.count("orange")>0:print("Exists")else:print("Doesn't exist")# Exists ...
