Extra line in output when printing inside a loop
python
Solution
The trailing `,` in the print statement will surpress a line feed. Your first print statement doesn't have one, your second one does.
The input you read still contains the `\n` which causes the extra linefeed. One way to compensate for it is to prevent print from issuing a linefeed of its own by using the trailing comma. Alternatively, and arguably a better approach, you could strip the newline in the input when you read it (e.g., by using `rstrip()` )
Problem
I can't figure out why the code #1 returns an extra empty line while code #2 doesn't. Could somebody explain this? The difference is an extra comma at the end of the code #2. ``` # Code #1 file = open('tasks.txt') for i, text in enumerate(filer, start=1): if i >= 2 and i <= 4: print "(%d) %s" % (i, text) # Code #2 file = open('tasks.txt') for i, text in enumerate(filer, start=1): if i >= 2 and i <= 4: print "(%d) %s" % (i, text), ``` Here is the content of my tasks.txt file: ``` line 1 line 2 line 3 line 4 line 5 ``` Result from code #1: ``` (2) line 2 (3) line 3 (4) line 4 ``` Result from code #2 (desired result): ``` (2) line 2 (3) line 3 (4) line 4 ```
