Atharva is a programmer, who has recently been given a task to write a Python code to perform the following binary file operation with the help of a user defined function/module : - Copy_new() : to create a binary file new_items.dat and write all the item details stored in the binary file, items.dat, except for the item whose item_id is 101. The data is stored in the following format : {item_id:[item_name,amount]} import ______ # Statement 1 def Copy_new(): f1= ______ # Statement 2 f2= ______ # Statement 3 item_id=int(input("Enter the item id")) item_detail= ______ # Statement 4 for key in item_detail: if ______: # Statement 5 pickle. ______ # Statement 6 f1.close() f2.close() He has succeeded in writing partial code and has missed out certain statements. Therefore, as a Python expert, help him to complete the code based on the given requirements : (i) Which module should be imported in the program ? (Statement 1) (ii) Write the correct statement required to open the binary file "items.dat". (Statement 2) (Option for part iii only) (iii) What should Atharva write in Statement 5 to apply the given condition and in Statement 6 to write data in the binary file "new_items.dat".

(i) How are text files different from binary files? (ii) A Binary file, CINEMA.DAT has the following structure: {MNO:[MNAME, MTYPE]} Where MNO – Movie Number, MNAME – Movie Name, MTYPE is Movie Type. Write a user defined function, findType(mtype), that accepts mtype as parameter and displays all the records from the binary file CINEMA.DAT, that have the value of Movie Type as mtype.

(b) (i) Give one difference between write() and writeline() function in text file. (ii) A Binary file, "Items.dat" has the following structure : [Icode, Description, Price] Where Icode – Item code Description – Detail of item Price – Price of item Write a function Add_data(), that takes Icode, Description and Price from the user and writes the information in the binary file "Items.dat".

Surya is a manager working in a recruitment agency. He needs to manage the records of various candidates. For this, he wants the following information of each candidate to be stored: - Candidate_ID – integer - Candidate_Name – string - Designation – string - Experience – float You, as a programmer of the company, have been assigned to do this job for Surya. (I) Write a function to input the data of a candidate and append it in a binary file. (II) Write a function to update the data of candidates whose experience is more than 10 years and change their designation to "Senior Manager".

Keshav is the IT Head in a hospital. He needs to manage the records of all the doctors in the hospital. For this, he wants to store the following information of each doctor in a file : D_ID – An integer to store Doctor ID. D_Name – A string to store doctor's name. D_Dept – A string to store the Department of the doctor. (Surgery, Radiology, etc.) Experience – An integer to store doctor's experience (in years) For example, a doctor's information may be : [1256, 'R. Gupta', 'Cardiology', 15] As an applicant for the post of a Programmer, you have to answer the following questions in this context : (I) Write one difference of storing this data in a binary file over a CSV file. (II) Assume that the data is stored in a binary file, named DOCTORS.DAT, and each record is stored as a list. Write a function, in Python, to read and display all the records from the file DOCTORS.DAT. (III) Write a function addDoctor(), in Python, which accepts a doctor's data from the user and writes it in the file DOCTORS.DAT.

Mr. Ravi, a manager at a tech company, needs to maintain records of employees. Each record should include: Employee_ID, Employee_Name, Department and Salary. Write the Python functions to: I.

NextStep is an organization which has a pool of resource persons to conduct training workshops on various topics related to ICT. The data of all its Resource Persons is stored in a binary file RESOURCES.DAT using the following record structure (each record is a tuple) : (R_ID, R_Name, R_Expertise, Charges) where : · R_ID – Resource Person's ID (An integer) · R_Name – Resource Person's Name (A string) · R_Expertise – Area of expertise of the Resource Person · Charges – Charges (in rupees) per hour to conduct a workshop For example, a record in the file is : (12, 'P. Velusami', 'Machine Learning', 5000) In this context, write the following user defined functions in Python : (i) Append() – To input the data of a Resource Person and write it in the file RESOURCES.DAT. (ii) Update() – To increase the Charges of each resource person by 500.
