The `seek()` method is used to change the current position of the file pointer within the file. It takes one argument, which is the offset from the specified position.
Example 1: Move the file pointer to the beginning of the file using `seek(0)`
with open('example.txt') as f:
f.seek(0)
print(f.readline())
Output: The first line of the file
Example 2: Move the file pointer to the end of the file using `seek(0, 2)`
with open('example.txt') as f:
f.seek(0, 2)
f.write('This is a new line')
Output: None
