Is there a way to write this C/C++ code in Python?
a = (b == true ? "123" : "456" )
C++ Solutions
Solution 1 - C++
a = '123' if b else '456'
Solution 2 - C++
While a = 'foo' if True else 'bar'
is the more modern way of doing the ternary if statement (python 2.5+), a 1-to-1 equivalent of your version might be:
a = (b == True and "123" or "456" )
... which in python should be shortened to:
a = b is True and "123" or "456"
... or if you simply want to test the truthfulness of b's value in general...
a = b and "123" or "456"
? :
can literally be swapped out for and or
Solution 3 - C++
My cryptic version...
a = ['123', '456'][b == True]
Solution 4 - C++
See PEP 308 for more info.
