03-07 map函數-list()-split()詳解

1、 源碼及輸出

list=input() 
b=list.split(" ")
print(b)              #這裡b已經是個list
a=map(int,b)          
print(a)			  #map後傳回的是個位址

print(list(a))        #這一句報錯
           

12 34 56 67
Traceback (most recent call last):
  File "D:/爬蟲/chengdu/LianJia/練習.py", line 23, in <module>
    print(list(a))
TypeError: 'str' object is not callable
['12', '34', '56', '67']
<map object at 0x00000000026FE550>
           

2、

score=list(map(int,input().split()))
print(score)

傳回值：
1 2 3 4 5
[1, 2, 3, 4, 5]         #傳回值為list


score=map(int,input().split())
print(score)

傳回值：
1 2 3 4 5
<map object at 0x00000000026FE550>  #結果為記憶體位址
