python - Filter df when values matches part of a string in pyspark

Question

I have a large pyspark.sql.dataframe.DataFrame and I want to keep (so filter) all rows where the URL saved in the location column contains a pre-determined string, e.g. 'google.com'.

I have tried:

import pyspark.sql.functions as sf
df.filter(sf.col('location').contains('google.com')).show(5)

but this throws a

TypeError: _TypeError: 'Column' object is not callable'

How do I go around and filter my df properly? Many thanks in advance!

Answer 1

Spark 2.2 onwards

df.filter(df.location.contains('google.com'))

Spark 2.1 and before

You can use plain SQL in filter

df.filter("location like '%google.com%'")

or with DataFrame column methods

df.filter(df.location.like('%google.com%'))
