Learning

Raw_input () and sys. stdin. readline ()

Raw_input () does not contain the last line break of \ n, while the latter has

Sys. stdin. readline (). strip (), no parameter. By default, spaces and line breaks are removed.

. Spilt () and separate the input data by space.

IDE

Debug Comprehension

Console input cannot be displayed immediately

Because pycharm enables buffering

Psyco. full ()

Sometimes it does cause RE

Good code indentation and spaces

Predefined mode is faster

If a in B []

For Loop

No problem. You can use a loop String. If you do not want \ n (this question does not affect the result, but multiple functions are called), use [:-1: the operation is a great benefit of py.

Both the conception and debugging are independently completed.

Come on!
