Python 3.5.1 - 将多个输入读入数组 [英] Python 3.5.1 - read multiple inputs into an array

问题描述

我正在使用 python 3.5.1 并通过 Windows 上的命令提示符运行我的文件.程序运行后传递参数；即程序根据之前生成的列表提示输入.

I'm using python 3.5.1 and running my file through command prompt on windows. The arguments are being passed after the program is run; ie the program prompts for input based on a previously generated list.

我希望在以空格分隔的同一行中读取多个数字.Python 2.X 使用 raw_input 不会有问题，但事实证明这是一个挑战.

I'm looking to read in multiple numbers on the same line separated by spaces. Python 2.X it wouldn't have been an issue with raw_input but this is proving to be a challenge.

selection = list(map(int,input("Enter items to archive (1 2 etc):").split(",")))

如果我在同一行输入两个不同的数字:

If I enter two different numbers on the same line:

输入要存档的项目(1 2 等):29 30 Traceback(最近调用最后):文件G:\Learning\Python\need_to_watch.py​​"，第 15 行，在selection = list(map(int,input("Enter items to archive (1 2 etc):").split(","))) File "", line 129 30^ 语法错误:解析时出现意外 EOF

Enter items to archive (1 2 etc):29 30 Traceback (most recent call last): File "G:\Learning\Python\need_to_watch.py", line 15, in selection = list(map(int,input("Enter items to archive (1 2 etc):").split(","))) File "", line 1 29 30 ^ SyntaxError: unexpected EOF while parsing

我放弃了单行并尝试只在循环中进行，但我得到了不同的错误

I gave up on a single line and tried just doing it in a loop but I get a different error

data=[]
while True:
        entry = int(input('Item number : '))
        data.append(entry)
        if entry == 'q':
            break

即使我没有 eval() 任何东西，它也会尝试将 'q' 评估为一个变量.

It tries to evaluate 'q' as a variable even though I haven't eval()'d anything.

这个问题说只使用 input().split() 但看起来这不再有效....接受多个用户输入在python中用空格分隔并将它们附加到列表中

This question says to just use input().split() but it would appear that this no longer works.... accepting multiple user inputs separated by a space in python and append them to a list

我可以尝试捕获 EOF 异常，但这似乎不是正确的方法，也没有必要.

I could try and catch the EOF exception, but that doesn't seem like the right way to do it, nor should it be necessary.

推荐答案

entry = input('Enter items: ')
entry = entry.split(' ')
entry = list(map(int, entry))
print(entry)

或者更简洁:

entry = list(map(int, input('Enter items: ').split(' ')))
print(entry)
