Python內建函數input

英文文檔：

input([prompt])

If the prompt argument is present, it is written to standard output without a trailing newline. The function then reads a line from input, converts it to a string (stripping a trailing newline), and returns that. When EOF is read, EOFError is raised

說明：

　　1. 如果提供了promat參數，首先將參數值輸出到標準的輸出，並且不換行。函數讀取使用者輸入的值，將其轉換成字串。

>>> s = input('please input your name:')please input your name:Ain>>> s'Ain'
