Python：为什么不抛出异常？

Question

为什么不抛出异常？

TypeError: cannot concatenate 'str' and 'int' objects

Answer 1

你可以像这样捕捉异常：

try:
    print "test" + 1
except ValueError:
    print "You can't concatenate that different object types silly"
except TypeError:
    print "TypeError and the words you want to say"
