Can you identify this code to see where each of these structures the Python Program? please identify all of them I need it.... thank you so much

1. Sequential Structures
2. Decision Structures
3. Repetition Structures
4. String Methods
5. Text File Manipulation
6. Lists and Dictionaries
7. Functions
8. Program Modularization

import numpy px_terms = int(input('enter number of terms in px ')) qx_terms = int(input('enter number of terms in qx ')) px_list = () qx_list = () for i in range(px_terms): ele = int(input('enter coefficient '+str(i+1)+' for px ')) px_list += (ele,) for i in range(qx_terms): ele = int(input('enter coefficient'+str(i+1)+' for qx ')) qx_list += (ele,) option = input('select Addition, Subtraction, Multiplication, Division: ') if option == "Addition": print(numpy.polynomial.polynomial.polyadd(px_list, qx_list)) if option == "Subtraction": print(numpy.polynomial.polynomial.polysub(px_list, qx_list)) if option == "Multiplication": print(numpy.polynomial.polynomial.polymul(px_list, qx_list)) if option == "Division": qu, re = numpy.polynomial.polynomial.polydiv(px_list, qx_list) print("Quotient: ", qu) print("Remainder: ", re)
