I am writing a program in which i open up a file and read the contents then do some calculations and update the information but in a new file. So my question is how do i go about declaring the new file so that the program will know that the new information goes into the new file and not the original? if it helps here is the code that i have so far: def startUp(): # Purpose: opens files and print report headings global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay payFile=open("payroll.txt", "r") payFile.readline()
def readRecord(): # Purpose: reads a record global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay employeeRec = payFile.readline() if employeeRec == "": eof = True else: # parse file line for record fields and format/convert for final output empName = employeeRec[0:25].strip() previousYTD = float(employeeRec[25:40]) payRate = float(employeeRec[40:55]) hoursWorked = float(employeeRec[55:70]) recordCount += 1 eof = False def writeRecord(): # Purpose: writes the updated record to the output file #Parameter global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay def processRecords(): # Purpose: loops through input file and processes each record global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay while not eof: calculatePay() printReportLine() writeRecord() readRecord() def calculatePay(): # Purpose: calculates pay and updated YTD # Return values: float - calculated pay, float - updated YTD amount global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay def printReportLine(): # Purpose: prints employee pay information # Parameters passed: float - calculated pay, float - updated YTD amount global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay def closeUp(): # Purpose: end of program housekeeping global empName, previousYTD, payRate, hoursWorked, recordCount, eof, payFile, \ payFileUpdated, newYTD, currentPay payFile.close() payFileUpdated.close() print "\nNumber of records in the file was",recordCount any and all help is appreciated. -- http://mail.python.org/mailman/listinfo/python-list
