Optimizing Continuous Levels in Instructions with Python Code
To achieve this, you can use the following Python code:
import pandas as pd from datetime import timedelta # Read the table into a DataFrame df = pd.read_csv('table.csv') # Sort the DataFrame by timeFrom df.sort_values(by='timeFrom', inplace=True) # Initialize an empty list to store the final instructions final_instructions = [] # Iterate over the sorted DataFrame for i in range(len(df)): current_instruction = df.iloc[i] # If this is not the first instruction and its levelTo is less than or equal to # the previous instruction's levelFrom, it means the levels are still continuous.
