The difference between python2.x and python3.x

1. The difference between raw_input() and input() in python2.x and python3.x

1、 In Python2.x, raw_input() and input( ), both functions exist, the difference is

raw_input( )--- treat all input as string and return the string type

input( )-----can only receive "digital" input, has its own characteristics when treating pure digital input, it returns the type of the input number (int, float)

2. In python3.x, raw_input() and input() are integrated, raw_input() is removed, and only the input( )** function is retained, which accepts arbitrary input and defaults all inputs For string processing, and return the string type.
