Read a file line by line. Python also has the fileinput module. Print 'Cannot read file' end if. Aug 27, 2014 readlines() is a function in python used to read text file and convert it into list where each line in at file is a element in list with new line( n).

What's wrong with your code? I find it to be quite elegant and simple. The only problem is that if the file doesn't end in a newline, the last line returned won't have a ' n' as the last character, and therefore doing line = line[:-1] would incorrectly strip off the last character of the line. The most elegant way to solve this problem would be to define a generator which took the lines of the file and removed the last character from each line only if that character is a newline: def strip_trailing_newlines(file): for line in file: if line[-1] == ' n': yield line[:-1] else: yield line f = open('myFile.txt', 'r') for line in strip_trailing_newlines(f): # do something with line. Long time ago, there was Dear, clean, old, BASIC code that could run on 16 kb core machines: like that: if (not open(1,'file.txt')) error 'Could not open 'file.txt' for reading' while(not eof(1)) line input #1 a$ print a$ wend close Now, to read a file line by line, with far better hardware and software (Python), we must reinvent the wheel: def line_input (file): for line in file: if line[-1] == ' n': yield line[:-1] else: yield line f = open('myFile.txt', 'r') for line_input(f): # do something with line I am induced to think that something has gone the wrong way somewhere.
