Type Mixin

class data_classes.Type_Mixin.TypeMixin

Bases: object

A mixin class providing various static methods for data conversion and output operations.

array_2_df(array, column_names)

Convert a numpy array to a pandas DataFrame with specified column names.

binary_arr_2_integer_arr(binary_arr, byte_order, signed_flag)

Convert an array of binary data to an array of integers.

arr_2_matrix(arr, num_rows, num_cols)

Reshape a numpy array into a 2D matrix with specified number of rows and columns.

output_df_2_excel(df, file_dir, sheet_name)

Output a DataFrame to an Excel sheet.

static arr_2_matrix(arr, num_rows, num_cols)

Reshape a numpy array into a matrix (2D array) with the specified number of rows and columns.

Parameters:

  • arr (numpy.ndarray) – A numpy array to be reshaped.

  • num_rows (int) – The number of rows for the resulting matrix.

  • num_cols (int) – The number of columns for the resulting matrix.

Returns:

The reshaped matrix (2D array).

Return type:

numpy.ndarray

static array_2_df(array, column_names)

Convert a numpy array to a pandas DataFrame with the given column names.

Parameters:

  • array (numpy.ndarray) – A numpy array to be converted into a DataFrame.

  • column_names (list of str) – A list of column names for the DataFrame.

Returns:

The resulting DataFrame with the specified column names.

Return type:

pandas.DataFrame

static binary_arr_2_integer_arr(binary_arr, byte_order, signed_flag)

Convert an array of binary data to an array of integers.

Parameters:

  • binary_arr (list of bytes) – A list of byte sequences (binary data).

  • byte_order (str) – A string indicating the byte order (‘big’ or ‘little’).

  • signed_flag (bool) – A boolean indicating whether the integers are signed (True) or unsigned (False).

Returns:

A numpy array of integers converted from the binary data.

Return type:

numpy.ndarray

static output_df_2_excel(df, file_dir, sheet_name)

Output a DataFrame to an Excel sheet.

Parameters:

  • df (pandas.DataFrame) – The DataFrame to be written to an Excel file.

  • file_dir (str) – The file path of the Excel file to write to.

  • sheet_name (str) – The name of the sheet where the data should be written.

Notes

Error handling should be added to ensure the file can be written correctly.
