Question

In PYTHON:Implement a function payroll() that takes two string parameters the first of which

represents the name of an input file and the second of which represents the name of an

output file. The input file contains lines with the following format: hours pay_rate where

hours is an integer representing a number of hours worked and pay_rate is a floating

point value representing the pay rate per hour. There will be some whitespace between

the two values, although you may not make any assumptions about how much or what

type. The function reads the input file line by line, computing the total pay (i.e. the

product of the hours times the pay_rate -- we are not assuming overtime is computed for

any of the values) and writing each amount to a newline in the output file. If the file is

empty, the function should not write any numbers to the output file. Note that the strings

read from the file will need to be evaluated before you can use them for

computations. The following shows what the function would return when called on

several sample files found in the zip file containing the assignment template. The output

files produced are also in the zip file:

Explanation / Answer

The code for above problem using python is given as:

#function to read and to write in file
def payroll(str1,str2):
#open files to read and write
file = open(str1, 'r')#in read mode
file1 = open(str2, 'w')#in write mode
for line in file:#to read file line by line
wordList = []#initialize empty array to read word in a line

for word in line.split():
#split line on the basis of white character
wordList.append(word) #adding words in List
result=float(wordList[0])*float(wordList[1])
#now you know that there will be 2 words only one line.So using index 0 and 1
   file1.write(str(result)+" ")
#writing output in output file
file1.close()
file.close()

payroll("pay1.txt","out1.txt")#calling function

f1=open("out1.txt",'r')#reading output file
print(f1.read())
f1.close()
