Python - 使用 Pyspark 检查单个值是否在 with.isin() 列中是否正确？

Question

In PySpark when I want to check if one of the values is in a column I use .isin() :

F.col('metric').isin({"Metric_value1, Metric_value2"})

Is it correct to perform the same check for a single value like below or there's a better way to do this?

F.col('metric').isin({"Metric_value1"})

Answer 1

In Pyspark, isin() is generally used to compare a column value against multiple values and return results if any of those values matches the column value.

For a single value, you could directly use comparison operator like:

F.col('metric')=='Metric_value1'
