write dataframe to delta parquet

Question

Hello,
I know how to read the delta parquet files in to a dataframe
example:
df_delta = spark.read.format("delta").load("...folder_path...")

Question:
How is it possible to write the result of a dataframe into delta parquet files ?
example?
df.write.format("delta").mode("overwrite").save(f"abfss://curated@{storage_account_name}.dfs.core.windows.net/folderpath")

The above line gives error as:

AnalysisException Traceback (most recent call last)
<command-3137735205505607> in <module>

8 df = spark.sql(strSQL)
----> 9 df.write.format("delta").mode("overwrite").save(f"abfss://curated@{storage_account_name}.dfs.core.windows.net/folderpath")

738 self._jwrite.save()
739 else:
--> 740 self._jwrite.save(path)

Thank you

Answer 1

solved as the cause of having brackets which is not allowed in parquet.
