Python file method read() reads at most size bytes from the file. If the read hits EOF before obtaining size bytes, then it reads only available bytes.
Following is the syntax for read() method −
fileObject.read( size );
size − This is the number of bytes to be read from the file.
This method returns the bytes read in string.
The following example shows the usage of read() method.
This is 1st line This is 2nd line This is 3rd line This is 4th line This is 5th line
#!/usr/bin/python # Open a file fo = open("foo.txt", "rw+") print "Name of the file: ", fo.name # Assuming file has following 5 lines # This is 1st line # This is 2nd line # This is 3rd line # This is 4th line # This is 5th line line = fo.read(10) print "Read Line: %s" % (line) # Close opend file fo.close()
When we run above program, it produces following result −
Name of the file: foo.txt Read Line: Python is
