This project introduces a Sheet class, a simple spreadsheet implementation in Python. The Sheet class provides functionality to manipulate data in a tabular format. Users can interact with the sheet by setting, retrieving, editing, and deleting values in specific cells. Additionally, the class supports basic formula evaluation for dynamic cell calculations.
sheet.py: Contains the implementation of theSheetclass.script.py: A script demonstrating the usage of theSheetclass.
Execute the script.py file using the following command:
python script.pyThe Sheet class is the core component of this project, offering a basic spreadsheet functionality. Below are key features and methods of the Sheet class:
from sheet import Sheet
# Create a new Sheet instance
sh = Sheet()Cells are identified using a combination of column letters and row numbers (e.g., "A1", "B2"). The class provides methods to convert these string indices into row and column indices.
# Convert cell index from string to row and column indices
row, col = sh.__resolve_index("B3")The Sheet class provides methods to set, get, edit, and delete values in cells.
# Set a value in a specific cell
sh.set_value("A1", 42)
# Retrieve the value from a cell
value = sh.get_value("A1")
# Edit the value in a cell
sh.edit_value("A1", 100)
# Delete the value in a cell
sh.delete_value("A1")Formulas can be assigned to cells, allowing dynamic calculations based on other cell values.
# Set a formula in a cell
sh.set_value("B3", '=A1 + A2')
# Retrieve the result of a formula
result = sh.get_value("B3")The resize method allows resizing the sheet to a specified number of rows and columns.
# Resize the sheet to 5 rows and 5 columns
sh.resize(5, 5)The script.py file provides examples demonstrating the usage of the Sheet class, including setting values, performing calculations with formulas, and more.
# Example usage in script.py
from sheet import Sheet
sh = Sheet()
sh.set_value("A1", 10)
sh.set_value("B1", 20)
result = sh.get_value("A1") # {'value': 10, 'result': 10}
sh.set_value("C1", '=A1 + B1')
result = sh.get_value("C1") # {'value': '=A1 + B1', 'result': 30}
