Question

txt文件是这样的。

50 70 60

40 30 80

30 80 40

结果txt文件是这样的。

50 70 60 60

40 30 80 50

30 80 40 50

到目前为止，我确实喜欢这样。但是，我无法获得结果，而且我也无法获得结果。得到平均值

f=open("sample.txt")
lines=f.readlines()
    for line in lines:
    f2=open("result.txt", 'w')
    for i in range(len(lines)):
        each_score=line.split()
        f2.write(str(map(int, each_score)))
f.close()
f2.close()

Answer 1

我的代码存在问题，因此我尽可能地使用它。

Alamofire.request("https://...",
                   method: .get,
                   parameters: ["myKey1": "myValue1"], 
                   encoding: JSONEncoding.default,
                   headers: self.authHeader).responseJSON { response in 
                        //your response
                   }

评论您的理解。

输出：

f=open("sample.txt")
lines=f.readlines()

f2=open("result.txt", 'w')

for line in lines:
    line = line.strip()
    if line == '':
        continue
    # Set each value as an integer into a list.
    each_score = [int(num) for num in line.split()]
    # Get average from sum/length.
    avg = int(sum(each_score) / len(each_score))
    # Create output list with item as str and include avg.
    output = [str(item) for item in (each_score + [avg])]
    # Finally write the line by joining the values.
    f2.write(' '.join(output) + '\n')

f.close()
f2.close()

读取txt文件并计算每行的平均值并将其写入新文件
