File exercise!

Download this file: big.txt

  1. Calculate number of bytes in file
  2. Number of occurrences of the letter 'z' in file
  3. Number of occurrences of all letters (case insensitive) in file

file_ = open("big.txt")
count = 0
for line in file_:
    for char in line:
        count += 1
print(count)
