Python Program to Append to a File – 2025

Hey guys, in this blog we will see a Python Program to Append to a File.

The content of the file my_file.txt is

Machine Learning Projects
Deep Learning Projects
Flask Projects

Open the file in append mode and write to it

with open("my_file.txt", "a") as f:
   f.write("CV Projects")

Output

Machine Learning Projects
Deep Learning Projects
Flask ProjectsCV Projects

• Simply open the file in ‘a’ mode which stands for append mode.
• Now write anything that you want to add to the file.
• We have added ‘CV Projects’ and it got added directly after ‘Flask Projects’.
• If you want to add items in the next line you do something like the following:

with open("my_file.txt", "a") as f:
   f.write("\nCV Projects")
