在交互式環境中，執行上述代碼后，會直接輸出?3.14，而不需要顯式調用?print()。這是因為 Python 的交互式環境會將表達式的計算結果作為返回值自動顯示。然而，在腳本文件（如?.py?文件）中運行相同的代碼時，如果沒有使用?print()，則不會輸出任何內容，因為腳本模式不會自動打印表達式的返回值。因此，在腳本中需要顯式使用?print()?來顯示結果

評論區這個程序可以參考：
T = ((1+2), ((1+2),), ('a'+'b'), (1, ), (1,2,3,4,5))
for a in T:
print(type(a))
結果：
<class 'int'>
<class 'tuple'>
<class 'str'>
<class 'tuple'>
<class 'tuple'>
T = ((1+2), ((1+2),), ('a'+'b'), (1, ), (1,2,3,4,5))
for a in T:
print(type(a))
結果：
<class 'int'>
<class 'tuple'>
<class 'str'>
<class 'tuple'>
<class 'tuple'>
