print(項目1 [,項目2 ,... (,sep=分隔字元,end=結束字
元]))
print()顯示的字串可以使用+進行組合,但不同型別
要先轉為文字

  1. a=123
  2. b=456
  3. print(a,"python",b)
  4. print(a,"python",b,sep="~")
  5. print(a,"python",b,sep="~",end="!!!\n")
  6. print(str(a)+"~python~"+str(b)+"!!!")

Ctrl+Alt+向下方向鍵    向下做單行複製
Ctrl+D    刪除單行
Ctrl+Z    回到上一步
F5    執行程式

a=98
b=89
print(a,"python",b)
print(a,"python",b,sep="~")
print(a,"python",b,sep="~",end="!!!\n")
print(str(a)+"~python~"+str(b)+"!!!")
