Question

My question would be if there was any other way besides below to iterate through a file one character at a time?

with open(filename) as f:
  while True:
    c = f.read(1)
    if not c:
      print "End of file"
      break
    print "Read a character:", c

Since there is not a function to check whether there is something to read like in Java, what other methods are there. Also, in the example, what would be in the variable c when it did reach the end of the file? Thanks for anyones help.

Answer 1

This is one way:

with open(filename) as f:
    for line in f:
        for c in line:
            pass

Or what about this?

with open(filename) as f:
    for c in f.read():
        pass
