readln() until EOF

a = open("Thefile.txt","r")

while ?????:
result = a.readln()

what do i put in ???? if i want to keep reading line by line until i
reach the end of the file?

I don't want to break the loop if there is a blank line, because there
will be.

Ex. of a file:

map1
result1

map2
result 2

map3
result3
comments

thanks...

the_file = open(path, 'r')
for this_line in the_file:
#do stuff with this_line

I assume you meant "a.readline()" ? Anyway...

a = open("path/to/file.ext")
for line in a:
do_something_with(line)
a.close()
