Here is the code so far:(THE PROBLEM WITH THE CODE IS THAT THE IM SUPPOSE TO USE FIND() TO REPEATEDLY CHANGE THE OCCURRENCE OF THE WORD "MASK" TO THE WORD "HAT" IN THE FILE BUT AM KIND OF LOST HAVE BEEN WORKING ON THIS FOR A WEEK AND A HALF) ALSO I CAN NOT use the replace method, count method, split method, range() function, or lists in your solution. HAVE BEEN TRYING TO FIND SUM WAY TO USE FIND() BUT AM COMING UP SHORT

 

CODE:

#Get input file name

fileOne = input("Enter the input file name :")

#Get output file name

fileTwo = input("Enter the output file name :")

'''Get a string that will be searched in the source file

to locate all occurrences of the string'''

targetString = input("Enter the target string :")

'''Get a string that will replace each occurrence of the target

string in the source file'''

replacementString = input("Enter the replacement string :")
files =input("Enter a file with the word 'mask':")
#Open the input file in read mode

f1 = open(fileOne,"r+")

#Read the content of input file

content =f1.read()

#Replace the target string with the replacement string
content =f1.find('mask')
print(files[0:content]+ "hat"+ files[content +content:len(files)])
#Open the output file in write mode

f1 = open(fileTwo,"w")
* IM SUPPOSE TO EXECUTE THE PROBLEM USING THE PRINT STATEMENT BUT IVE BEEN COMING UP SHORT OVER ND OVER AGAIN*


f1.close()

 

 
Enter the input file name: inFile.txt
Enter the output file name: outFile.txt
Enter target string: mask
Enter the replacement string: hat
inFile.txt for this example contains:
overview
wear masks with two or more layers to stop the spread of COVID-19
wear the mask over your nose and mouth and secure it under your chin
masks should be worn by people two years and older
- masks should NOT be worn by children younger than two, people who have

- CDC does not recommend the use of face shields alone. Evaluation of få
- evaluation of mask and gaiter materials and structure is ongoing.
outFile.txt, after replacing each occurrence of the string 'mask' with 'hat' looks like this:
Overview

- wear the hat over your nose and mouth and secure it under your chin
hats should be worn by people two years and older

- evaluation of hat and gaiter materials and structure is ongoing.
All strings are case-sensitive. That is, 'the' will NOT match 'The' in the source string.
