"Everything is a pointer".

Here's a list of records:

[(1, "moshe"), (2, "gbp")

And here's code to turn this file

'''
1:moshe
2:gbp
'''

Into such a list:

def make_lor(file):
	ret = [] # an empty list
	lines = file.readlines() # read all lines from the file
	for line in lines: 
		number, name = string.split(line, ':')
		number = int(number) #  turn "number" into an integer
		record = (number, name) # a tuple
		ret.append(record) # append this
	return ret # return the created list
