[Tutor] Reading a Text File with tkFileDialog, askopenfilename+enumerate

[Wayne Watson]

Title: Signature.html

A three questions about askopenfilename and enumerate. For askopenfilename: 1. Do I have to close the file before exiting from it? 2. How do I read each line of text in the file and quit when an eof is reached? This certainly doesn't do it.     def OpenConfigFile(self):                 config_file = askopenfilename( title="Open Configuration File",                                     filetypes=CEN_FILE_TYPES )         print "cfile-------: ",config_file, type(config_file)         for it in config_file:              config_file.readline(aline)              print aline         pass         print "finished the file" I get a "'str' object has no attribute 'readline'" msg trying to read a text file, Initial.sen, which is a text file and of type 'str'. 3. Where can I find out more about enumerate, as used here: input_file=open('Initial.sen','r') for (line_cnt, each_line) in enumerate(input_file):     print each_line input_file.close() I used this small program for other purposes in the distant past, but what's going here with enumerate? Documentation for enumerate seems scarce. BTW, is there a thorough document on the use of files in Python out there somewhere? -- Wayne Watson (Watson Adventures, Prop., Nevada City, CA) (121.01 Deg.
