Hello,
I have this string called test with the contents of 'het is een wonder \\TIS'
Now I want to get rid of the \\ so I do this : test2 = test.replace ('\\', '')
And I get at the python prompt this answer : 'het is een wonder TIS'
So that's right.
Now I try the same in a IDE with this programm :
woorden =[]
letter_counts = {}
file = open ('alice_in_wonderland.txt', 'r')
for line in file:
line2 = line.replace ("\\","")
line3 = line2.lower()
woorden = line3.split()
for letter in woorden:
letter_counts[letter] = letter_counts.get (letter, 0) + 1
letter_items = letter_counts.items()
letter_items.sort()
print letter_items
But now Im gettting this output :
[('"\'tis', 1),
Why does the \ stays here. It should have gone as the test in the python
prompt says.
I ran your program against a 1 line file containing 'het is een wonder
\\TIS'
The result I get is [('een', 1), ('het', 1), ('is', 1), ('tis', 1),
('wonder', 1)]
Dunno why you are getting a different result.
Here is where using the debugger and going step by step can help. I have
no experience with the IDLE debugger. Perhaps others can offer advice on
that.

Hello everyone.
Chancing to (r\\, '') or (\\\\, '') did not help.
I know that there were more outcome. I would only let see that on the python
prompt the \ is deleted and if I use Eclipse the / stays when I use the text
from alice in wonderland.
And im still wondering why this happens.
Maybe put the text from alice into the python prompt and look what happens.
