Python脚本

Question

我有以下形式的数据：

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，据我所知，Python是非常强大的这种愚蠢的任务，但我对语法不是很熟悉，那么完成这个目标的最好方法是什么？

也许是这样的：

#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中运行本程序和数据反馈，然后抓出结果？

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函数来获取数字，然后按需要打印它。请注意错误处理以检查它是否为整数，或者如果该行有：或不是

不确定你的意思是shell，但是你可以创建一个函数，然后调用一个函数：
