>>> df = session.create_dataframe([[1, 2], [3, 4]], schema=["A", "B"])
>>> df_filtered = df.filter((col("A") > 1) & (col("B") < 100))  # Must use parenthesis before and after operator &.

>>> # The following two result in the same SQL query:
>>> df.filter(col("a") > 1).collect()
[Row(A=3, B=4)]
>>> df.filter("a > 1").collect()  # use SQL expression
[Row(A=3, B=4)]
