Python腳本

Question

我有以下形式的數據：

Overall evaluation: 2 
Invite to interview: 3 
Strength or novelty of the idea (1): 3 
Strength or novelty of the idea (2): 3 
Strength or novelty of the idea (3): 4 
Use or provision of open data (1): 3 
Use or provision of open data (2): 2 
"Open by default" (1): 3 
"Open by default" (2): 2 
Value proposition and potential scale (1): 3 
Value proposition and potential scale (2): 2 
Market opportunity and timing (1): 3 
Market opportunity and timing (2): 2 
Triple bottom line impact (1): 3 
Triple bottom line impact (2): 2 
Triple bottom line impact (3): 3 
Knowledge and skills of the team (1): 2 
Knowledge and skills of the team (2): 4 
Capacity to realise the idea (1): 3 
Capacity to realise the idea (2): 2 
Capacity to realise the idea (3): 3 
Appropriateness of the budget to realise the idea: 2 

我想渲染它，如下所示：

=2+3+3+3+4+3+2+3+2+3+2+3+2+3+2+3+2+4+3+2+3+2 

所以，據我所知，Python是非常強大的這種愚蠢的任務，但我對語法不是很熟悉，那麼完成這個目標的最好方法是什麼？

也許是這樣的：

#create an array 
#array = "=" 
f = open('data.txt', 'r') 
for line in f: 
    #number = grab that number off the end with some kind of regex 
    #array.append(number + "+") 

是否有可能只是在Python shell中運行本程序和數據反饋，然後抓出結果？

Answer 1

with open('data.txt', 'r') as f: 
    for line in f: 
     number = int(line.split(':')[1]) 
     array.append(number) 
print '+'.join(array) 

基本上，使用split函數來獲取數字，然後按需要打印它。請注意錯誤處理以檢查它是否爲整數，或者如果該行有：或不是

不確定你的意思是shell，但是你可以創建一個函數，然後調用一個函數：
