writing to file

[DreamingInsanity]

You can do something like this:

lines = infile.readlines() #put all the lines in an array
sizeOfGroups = 2
if len(lines) % sizeOfGroups == 1: #if it's an odd number of elements
    lines.remove(lines[-1]) #Remove the last element - you could always add a new element to the end intead of removing.
groups = [lines[n:n+sizeOfGroups] for n in range(0, len(lines), sizeOfGroups)] #use a list comprehension to split the big list into smaller sub lists with the size of 'sizeOfGroups'
for group in groups: #loop through each esub list
    outfile.write('({0}=={1}) and\n'.format(group[0].replace('\n',''), group[1].replace('\n',''))) #format and write to the outfile
outfile.close()

As it says in the comments of line 4, it removes the last element if the list is an odd number. You can always change it to this, so it adds a filler element:

lines = lines + ['-----']

In my opinion, this doesn't give you a very pretty output because it would be something like this:

Output:
(000123461==-----) and

Note: the list comprehension on line 5 is the same as this:

sub_lists = []
for n in range(0, len(lines), sizeOfGroups): #the extra parameter in range() tells it how much it increases by each time - for this it goes: 2, 4, 6 ....
    sub_lists.append(lines[n:n+sizeOfGroups]) #split the list into groups by taking the element 0-2 (2 not included so technically speaking 0-1) and so on.
