How do I make backslash (\\) work in IDLE?

问题:

I use a Mac and I use Shift + Alt + / when I want to type a \. I'm trying to learn Python and as you can see \ works fine, but not in IDLE.

How do I make backslash (\) work in IDLE?

回答1:

Since this problem still persists on OSX 10.8 with python 2.7.5 and 3.3.2 and since this is the first google hit when searching for backslash idle here is a more practical solution instead of copy and pasting: Go to:

idle->preferences->keys

Under Action-Keys replace:

expand-word <Option-Key-Slash>

with something you like for instance:

expand-word <Control-Option-Key-Slash>

This should fix it.

go to

idle -> preferences -> General -> default source encoding -> Locale-defined

回答3:

Copy-Paste it from notepad.
or
Use command line python shell.

回答4:

In IDLE, it worked with alt (option) + i.

回答5:

Everyone i have an excellent solution to this problem. Go to "Terminal":

Write

Python

Now it works because it's like using IDLE just in terminal and in terminal the backslash will work perfectly fine.
