Open
If we want to process a file for either read or write
operation, the file must be opened first. The opening of a file is done with
the help of open() method.
Keyword:
Open()Syntax:
file_object=open (file_name[,'mode'] [, buffering])The open() method returns a file object with allocated buffer size
when the specified file is successfully opened on the specified mode. The
file object refers the allocated buffer for file processing
operations.
Close
The close method used to clear the allocated buffer and
unwritten information and release the file object. No more read and write
operation can be done on the file object after that .
Keyword:
Close()Syntax:
file_object.close()The python produces an error message, if we try to close an unopened or unassigned file object.
Program:
# Open a file in read mode
file = open('file.txt', 'r')
# Read the content of the file
content = file.read()
# Print the content of the file
print(content)
# Close the file
file.close()
