Holy crap, a year and no update. In an attempt to get things going again, here's a simple post of something I keep looking up online.
Python has no ternary operator (?: in C++)
Instead, use an and-or construction:
In [1]: True and 'a' or 'b'
Out[1]: 'a'
In [2]: False and 'a' or 'b'
Out[2]: 'b'
Replace True and False with the condition:
In [3]: (1==1) and 'a' or 'b'
Out[3]: 'a'
In [4]: (1==0) and 'a' or 'b'
Out[4]: 'b'
Edit:
One failure of this method is then 'a' or 'b' can evaluate as boolean values. Examples of this behavior:
In [1]: True and True or False
Out[1]: True
In [2]: True and False or True
Out[2]: True
In [3]: True and 1 or 0
Out[3]: 1
In [4]: True and 0 or 1
Out[4]: 1
In [5]: True and 'a' or ''
Out[5]: 'a'
In [6]: True and '' or 'a'
Out[6]: 'a'
So you see that if the first return value evaluates as false, the second value is returned. I'll post a solution or workaround later, when I find one.
