How do you read files in python?

Answer 1

Assuming that the file contains just textual stuff, create an object to represent it:

stuff = file ( 'stuff.txt' )

To read a line of the file at a time:

line = stuff.readline()

Python signals end-of-file by returning an empty line which you can test for in a construction such as the following:

stuff = file ( 'stuff.txt' )

while True:

line = stuff.readline()

if line :

# do something here

pass

else :

break

You can read the entire file using :

whole_contents = stuff.read()

If the file had contained binary then it would have been necessary to open it as such:

stuff = file ( 'stuff.bn', 'b' )
