Python : How to overwrite the existing file content

We will read the text file in write (w) mode in this Python program. Let’s consider that we have a writecontent.txt file with the content below. We will write content for this file with mode with the help of the below-given steps.

# writecontent.txt

Line1 : This is India.
Line2 : This is America.
Line3 : This is Canada.
Line4 : This is Australia.

Steps to solve the program

1. Open the file by using open(“file_name”, “w”).
2. Where file_name is the file’s name and w is writing mode.
3. Using write() method write the data into the file this data will overwrite the previous data.
4. Close the file.

# Solution 1:

content = "New Line : This is China"

# open file and provide filename and write mode as (w)
file = open("writecontent.txt", "w")
file.write(content)   # write content to file using write method
file.close()              # close the file.


# Solution 2:  write content into file using function.

def write_content(filepath, content):
    file = open(filepath, "w")
    file.write(content)
    file.close()
    
write_content("writecontent.txt", content)  

Output: Once we add the written content to the file, the existing content will be overwritten, now open the writecontent.txt file, then only the newly added line will be available.
