Ok so im going to list my question and then the work so far. 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")

'''Write the content after all of the occurrences of the target

string have been found and replaced by the replacement string'''

f1.close()
