Example: res = {chr(x): xforxinrange(65,70)}print(res)# Result{'A':65,'B':66,'E':69,'D':68,'C':67} 总结 列表解析式在Python2中引入,集合与字典解析式在Python3中引入,后来同样也支持了Python2.7。 一般来说,应该多应用解析式,简短、高效。如果看到一个解析式过于复杂,则可以考虑将其层...
Ans: Yes, runtime errors exist in Python. For example, if you are duck typing and things look like a duck, then it is considered as a duck even if that is just a flag or stamp or any other thing. The code, in this case, would be A Run-time error. For example, Print “Hello...
