Question

我有两个仅包含数字的txt文件（每行数），所以我想将第1行和第1行连续添加到每个文件的最后一行。每个文件都有相同的行号。

我正在尝试这种方式，但我只能打印第一行

arq = open ("List1.txt")
arq2 = open ("List2.txt")

x = [linha.strip() for linha in arq]
arq.close()
y = [linha.strip() for linha in arq2]
arq2.close()

for linha in x:
    index = 0
    while index<len(x):
       result = (int(x[index]) + int(y[index]))
       index += 1
    print result

Answer 1

您可以使用zip轻松实现此目标。

将相关代码行更改为：

for x, y in zip(arq, arq2):
    result = int(x) + int(y)
    print(result)

Answer 2

虽然您应该使用上面提到的zip，但如果您想继续使用您的做事方式，那么您的问题就在这里

当你在python中循环for时，它是一个foreach，所以当你这样做时

for linha in x:
    print linha

linha将是x[n]的值，其中n是循环的迭代

无论如何，修复你要做的代码

# no need for the for loop, pull everything back
index = 0
while index< min(len(x), len(y)): # make sure you check for both lengths in case they are not the same
    result = (int(x[index]) + int(y[index]))
    index += 1
    print result # you want to print the result inside the loop so you don't lose it on the next iteration

这样做的正确方法是

for n,p in zip(x,y):
    print int(n) + int(p)

Answer 3

首先，我会得到一个numpy数组并连接

import numpy as np
file1 = np.genfromtxt('file1')
file2 = np.genfromtxt('file2')
file3 = np.concatenate((file1, file2), axis=1)

然后保存你认为合适的

txt文件中整数的总和
