Hi Alan,
There is an indent message in the revised code.
Question: Where should I indent the code line for the loop?
View the revised codes with loop indents, below:
--->Revised Code v.2 wo/indent from lines 8-12:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)
count = 0
addresses = set()
for line in fh:
if line.startswith('From'):
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
addresses.add(line)
count = count + 1
print "There were", count, "lines in the file with From as the first word"
print addresses
---> Message output reads:
In [62]: %run _8_5_v_25.py
File "C:\Users\vm\Desktop\apps\docs\Python\_8_5_v_25.py", line 8
line2 = line.strip()
^
IndentationError: expected an indented block
--->Revised Code v.3 w/indent from lines 8-12:
fname = raw_input("Enter file name: ")
if len(fname) < 1 : fname = "mbox-short.txt"
fh = open(fname)

addresses = set()
for line in fh:
if line.startswith('From'):
line2 = line.strip()
line3 = line2.split()
line4 = line3[1]
addresses.add(line)
count = count + 1
print "There were", count, "lines in the file with From as the first word"
print addresses
