pyspark-sql: print alias of an expression

0

In pyspark I have the following:

import pyspark.sql.functions as F
cc = F.lit(1).alias("A")

print(cc)
print(cc._jc.toString())

I get :

Column<b'1 AS `A`'>
1 AS `A`

Is there any way for me to just print "A" from cc ? it seems I'm unable to extract the alias easily.

Also I think that in spark-sql in scala, if I print "cc" it would just print "A" instead

  This post will guide you in the right direction stackoverflow.com/questions/39746752/…. However,based on the docs and this answer it seems like there is no way to do this without parsing the "AS" etc.
