Python 3 – Working with Files

• Data from an opened file can be read using any of the methods: read, readline and readlines.
• Data can be written to a file using either write or writelines method.
• A file must be opened, before it is used for reading or writing.

Example: Reading a file

fp = open('temp.txt', 'r')   # opening
content = fp.read()          # reading
fp.close()                   # closing
