How to replace a line in a file using python?

Question

Python

With this code, I can output line 3:

with open('1.txt') as f:
  line = f.readlines()[2]
print(line)

Content 1.txt:

11

I need to replace only 3 lines in file 1.txt

Answer 1

Let's say this:

with open('your_file.txt', 'r') as file:
    data = file.readlines()

print(data)

data[2] = '@micsma\n'
with open('your_file.txt', 'w') as file:
    file.writelines(data)
