teradataml.dataframe.sql.DataFrameColumn.bitwiseNOT = bitwiseNOT()
DESCRIPTION:
    Function performs a bitwise complement on the binary representation of integer or byte
    value in column. The bitwise NOT, or complement, is a unary operation which performs
    logical negation on each bit, forming the ones' complement of the specified binary value.
    The digits in the argument which were 0 become 1, and vice versa.
 
ALTERNATE NAMES:
    * bitnot
    * bitwise_not
 
RAISES:
    TypeError, ValueError, TeradataMlException
 
RETURNS:
    DataFrameColumn
 
EXAMPLES:
    # Load the data to run the example.
    >>> load_example_data("dataframe", "bytes_table")
 
    # Create a DataFrame on 'bytes_table' table.
    >>> df = DataFrame("bytes_table")
    >>> print(df)

    # Example1: Performs a bitwise complement operation on "varbyte_col" column and
    #           pass it as input to DataFrame.assign().
    >>> res_df = df.assign(col = df.varbyte_col.bitwiseNOT())
