Hi,
I have some wxPython code created with wxGlade that I am customizing.
I have a label created under the def __init__() section of the Frame
Class. It states...
self.Question = wx.StaticText(self, -1, "My question...")
if I insert a new line character in this string like this then the
output is placed on two lines as expected.
self.Question = wx.StaticText(self, -1, "My \nquestion...")
Output My
question
I am getting the question as an argument using sys.argv[] and putting
it in a variable called "question_text". The code is as follows...
question_text = "My \nquestion..."
self.Question = wx.StaticText(self, -1, question_text)
Output My \nquestion
How do I get the line text \n recognized so the break is inserted using
the variable technique like what happened when I actually used a string?
...in bash you would do "$question_text". Is there comparable macro
substitution in python.
In a Python script, a \n within a plain string literal such as "My
\nquestion..." will be treated as a newline character.
If you're getting the string from the command line, a \n will be
treated as backslash '\' followed by letter 'n', so it's equivalent to
the string literal "\\n".
In Python 2, you can unescape a string using its .decode method:
>>> "My \\nquestion..."
'My \\nquestion...'
>>> "My \\nquestion...".decode("string_escape")
'My \nquestion...'
