Here is some mostly tested code ;)

import re

file = open ("textfile.txt")  # your file name instead of textfile.txt
alllines = list(file.readlines())
file.close()

alllines.sort()

fruitre = re.compile('^[a-z]+')
fruits = {}
for line in alllines:
     fruitresult = fruitre.search(line)
     print line
     if fruitresult:
       fruit = fruitresult.group(0)
       fruits.setdefault(fruit, 0)
       fruits[fruit] += 1

totalamount = 0
for fruit, amount in fruits.items():
     print fruit, " occurs ", amount
     totalamount += amount

print "Total amount of fruits ", totalamount

PS: It looks a little unoptimized to me but it works. Hopefully others
will reply to you as well so I can learn how to make the above better.
