How to use seek() and tell() in Python
tell()
tell() returns the current position of the file pointer from the beginning of the file.
main.py
demofile.txt
f = open("demofile.txt", "r")# points at the startprint(f.tell())
seek()
If we want to move the file pointer to another position, we can use the seek() method.
Syntax
This method takes two arguments:
- f.seek(offset, fromwhere),
where
offsetrepresents how many bytes to move fromwhere, represents the position from where the bytes are moving.
main.py
demofile.txt
f = open("demofile.txt", "r")f.seek(4)print(f.readline())
