Plesae include the traceback, which will indicate WHERE you have a syntax error.

By using html, you have killed the indentation that you presumably had in your original. If you didn't have it in your original, then that's your second syntax error.

Untested, but this should work. Adding error checking is left up to you.
f = open('file.txt', 'r')
# each line looks like:
# d-d ccc...
# where d is a digit and c is any non-space character.
for line in f:
head, tail = line.split(' ')
head, num = head.split('-')
num = int(num)
for i in range(1, num+1):
print %s-%s %s % (head, i, tail)

So how does that works? Give me full explanation. The encoding declaration is parsed in the process of compiling the source. CPython uses the function get_coding_spec in tokenizer.c. CPython 2.7.3 source link: http://hg.python.org/cpython/file/70274d53c1dd/Parser/tokenizer.c#l205 You can use the parser module to represent the nodes of a parsed source tree as a sequence of nested tuples. The first item in each tuple is the node type number. The associated names for each number are split across two dictionaries. symbol.sym_name maps non-terminal node types, and token.tok_name maps terminal nodes (i.e. leaf nodes in the tree). In CPython 2.7/3.3, node types below 256 are terminal. Here's an example source tree for two types of encoding declaration: src1 = '# -*- coding: utf-8 -*-' parser.suite(src1).totuple() (339, (257, (0, '')), 'utf-8') src2 = '# coding=utf-8' parser.suite(src2).totuple() (339, (257, (0, '')), 'utf-8') As expected, src1 and src2 are equivalent. Now find the names of node types 339, 257, and 0: symbol.sym_name[339] 'encoding_decl' symbol.sym_name[257] 'file_input' token.ISTERMINAL(0) True token.tok_name[0] 'ENDMARKER' The base node is type 339 (encoding_decl). The child is type 257 (file_input), which is just the empty body of the source (to keep it simple, src1 and src2 lack statements). Tacked on at the end is the string value of the encoding_decl (e.g. 'utf-8'). ___ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: http://mail.python.org/mailman/listinfo/tutor
