Hi there,
I simply can't print anything in the second for-loop bellow:
#########################################
#!/usr/bin/env python
import sys
filename = sys.argv[1]
outname = filename.split('.')[0] + '_pdr.dat'
begin = 'Distance distribution'
end = 'Reciprocal'
first = 0
last = 0
with open(filename) as inf:
for num, line in enumerate(inf, 1):
#print num, line
if begin in line:
first = num
if end in line:
last = num
The file pointer is now at the end of the file. As an iterator, the file
is exhausted. To reiterate, return the file pointer to the beginning
with inf.seek(0).
for num, line in enumerate(inf, 1):
print 'Ok!'
print num, line
if num in range(first + 5, last - 1):
print line
print first, last
print range(first + 5, last - 1)
