Cannot find col function in pyspark

Question

In pyspark 1.6.2, I can import col function by

from pyspark.sql.functions import col

but when I try to look it up in the Githu

Answer 1

In Pycharm the col function and others are flagged as "not found"

a workaround is to import functions and call the col function from there.

for example:

from pyspark.sql import functions as F
df.select(F.col("my_column"))
