Python縮進

縮進出現問題,運行不出來。ide

正確代碼以下:spa

 1 def binary_search(list, item):
 2     low = 0
 3     high = len(list)-1
 4 
 5     while low <= high:
 6         mid = (low + high)
 7         guess = list[mid]
 8         if guess == item:
 9             return mid
10         if guess > item:
11             high = mid-1
12         else:
13             low = mid + 1
14     return None
15 
16 my_list = [1, 3, 5, 7, 9]
17 print (binary_search(my_list, 3)) # => 1

直接粘貼,以下,運行報錯

而後,選中所有,alt+ctrl+I自動縮進,以下:blog

仍然須要調整,選中,tab鍵,總體縮進it

直至最終能夠運行。event

目前看來,很不方便,也許還未掌握訣竅class
