[ Python File Methods](#)
* * *
### Overview
The **seek()** method is used to move the file read pointer to a specified position.
### Syntax
The syntax for the seek() method is as follows:
fileObject.seek(offset[, whence])
### Parameters
* **offset** -- The starting offset, which represents the number of bytes to move.
* **whence:** Optional, default value is 0. Defines the starting point for the offset parameter: 0 represents the beginning of the file, 1 represents the current position, and 2 represents the end of the file.
### Return Value
If the operation is successful, it returns the new file position. If the operation fails, the function returns -1.
### Example
The following example demonstrates the use of the readline() method:
The content of the file .txt is as follows:
1:www. 2:www. 3:www. 4:www. 5:www.
Loop to read the file content:
## Example
#!/usr/bin/python# -*- coding: UTF-8 -*-# Open file fo = open(".txt", "rw+")print"The file name is: ", fo.name line = fo.readline()print"The data read is: %s" % (line)# Reset the file read pointer to the beginning of fo.seek(0, 0)line = fo.readline()print"The data read is: %s" % (line)# Close file fo.close()
The output of the above example is:
The file name is: .txt The data read is: 1:www. The data read is: 1:www.
