Toll System Assignment: Data Science, Big Data, Python, and Tolls

This assignment focuses on analyzing a toll system using data science techniques and Python programming. The solution includes Python code to read data from a file, search for specific car records based on car numbers, and display the relevant toll information. The program defines functions to calculate the number of lines in the file and uses lists to store and manipulate the data. It also includes error handling for invalid input, such as incorrect car number lengths. The program allows the user to input a car number to search for, providing a user-friendly interface. The provided solution demonstrates how to process and analyze data from a toll system, making it a valuable resource for students studying data science and related fields. The assignment showcases practical applications of programming and data analysis in a real-world scenario. The code is designed to efficiently search and retrieve specific records, providing a practical solution for managing and analyzing toll data.
