How to edit specific line in text file in Python?
To edit specific line in text file in Python, we can call readlines to read all the lines in the text file.
And then we call writelines to write the new content into the same file after updating the file.
For instance, we write
with open('stats.txt', 'r') as file:
data = file.readlines()
data[1] = 'foo\n'
with open('stats.txt', 'w') as file:
file.writelines(data)
to call open to open stats.txt.
Then we call readlines to read in the whole file as a list.
Then we change 2nd line with
data[1] = 'foo\n'
Next, we open the same file with write permission with open.
And then we call writelines with data to write the updated content into the file.
