File handle is like a cursor, which defines from where the data has to be read or written in the file. Syntax: f.seek (offset, from_what), where f is file pointer. Parameters: Offset: Number of positions to move forward.

2 lip 2021 · In addition to the standard operations like reading and writing to the files, there are methods to manipulate the file pointer effectively. In this tutorial, you’ll learn how to use the seek() function to move the position of a file pointer while reading or writing a file.
The seek() method sets the current file position in a file stream. The seek() method also returns the new postion.
A seek () operation moves that pointer to some other part of the file so you can read or write at that place. So, if you want to read the whole file but skip the first 20 bytes, open the file, seek (20) to move to where you want to start reading, then continue with reading the file.
6 paź 2024 · In the digital world, files are like books, and just like you can navigate through a physical book, Python's seek() function allows you to move around within a file, positioning the file pointer to a specific location. This powerful function gives you the flexibility to manipulate files in ways that go beyond simple sequential reading or writing.
The seek() method allows you to change the current file position in a file object. It takes two arguments, offset for the number of bytes to move, and whence for the reference position (0 for the beginning of the file, 1 for the current position, and 2 for the end of the file).
The Python File seek() method sets the file's cursor at a specified position in the current file. A file's cursor is used to store the current position of the read and write operations in a file; and this method can move this file cursor forward or backward.
