Python File read() Method
The method read() at most size bytes from the file. If the read hits EOF before obtaining size bytes then it read 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.
#!/usr/bin/python # Open a file fo = open("foo.txt", "r") 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()
Let us compile and run the above program, this will produce the following result:
Name of the file: foo.txt Read Line: This is 1s
