- 5. 5 My python coding __author__ = 'RUCHA'# This program calculates monthly repayments on an interest rate loan/mortgage loanAmount = input("How much do you want to borrow? n") interestRate = input("What is the interest rate on your loan? n") repaymentLength = input("How many years to repay your loan? n") #converting the string input variables to float loanAmount = float(loanAmount) interestRate = float(interestRate)repaymentLength = float(repaymentLength)#working out the interest rate to a decimal number interestCalculation = interestRate / 100 print(interestRate) print(interestCalculation) #working out the number of payments over the course of the loan period. numberOfPayments = repaymentLength*12 #Formula#M = L[i(1+i)n] / [(1+i)n-1]# * M = Monthly Payment (what were trying to find out) # * L = Loan Amount (loanAmount)# * I = Interest Rate (for an interest rate of 5%, i = 0.05 (interestCalculation) # * N = Number of Payments (repaymentLength) monthlyRepaymentCost = loanAmount * interestCalculation * (1+interestCalculation) *numberOfPayments / ((1+interestCalculation) * numberOfPayments - 1)#THIS IS FROM ANOTHER BIT OF CODE THAT IS SUPPOSE TO BE RIGHT BUTISNT---# repaymentCost = loanAmount * interestRate * (1+ interestRate) * numberOfPayments / ((1+ interestRate) * numberOfPayments -1)#working out the total cost of the repayment over the full term of the loantotalCharge = (monthlyRepaymentCost * numberOfPayments) - loanAmountprint("You want to borrow £" + str(loanAmount) + " over " + str(repaymentLength) + "years, with an interest rate of " + str(interestRate) + "%!")print("Your monthly repayment will be £" + str(monthlyRepaymentCost))print("Your monthly repayment will be £%.2f " % monthlyRepaymentCost)print("The total charge on this loan will be £%.2f !" % totalCharge)
- 6. 2 3 1 What is debugging? It is the process of detecting and removing of existing and potential errors (also called as bugs) in a software code that can cause it to behave unexpectedly or crash. Reproduce the problem & Describe the bug. Try to get as much input from the user to get the exact reason. Capture the program snapshot when the bug appears. Try to get all the variable values and states of the program at that time. Analyse the snapshot based on the state and action. Based on that try to find the cause of the bug. 6
- 7. What’s an .exe? 7 ✔ An .exe is a very common file type. The .exe file extension is short for “executable.” These files are most commonly used on Windows® computers to install or run software applications.
- 8. Steps to Create an Executable from Python Script using Pyinstaller Add Python to Windows Path Open the Windows Command Prompt Install the Pyinstaller Package Create the Executable using Pyinstaller Save your Python Script 8
- 9. Prospective Aspects ❑ if we give proper User interface to this EXE. File then it will become a windows application. ❑ also if we convert previous program into APK. File & by giving user interface to same then it will also become mobile application 9
- 10. Conclusion Using a debugger can be tricky and time consuming, but it’s the most reliable way to find bugs in your code Exe files is a runtime system, which implements runtime language features and interactions with the operating system. 10 Python is compatible with all popular operating systems and platforms. Hence this language can be universally accepted by all programmers.
