Question
So i have this code right here but for some reason it takes my outfile and deletes it completely instead of changing every occurrence of the word mask with hat.
I CANT USE THE REPLACE METHOD,COUNT METHOD, RANGE(), LISTS, or SPLIT METHOD and have been struggling for a week now on this. Ive used the replace method by accident and don't know another way to do this.
#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 :")
#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
contentToWrite=content.replace(targetString, replacementString)
#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.write(contentToWrite)
