Question

有没有办法忽略通过raw_input输入的数据中的换行符？我正在尝试使用raw_input输入从电子表格中复制和粘贴的字符串列表。问题是看起来新行字符会导致数据过早输入。无论如何，所有空白空间都将被剥离，因此在输入数据时删除换行符将是一个额外的好处。此数据需要通过终端提示直接输入，而不是从文件中读取。

这是我到目前为止所做的：

names = raw_input('Shoot me some names partner: ')

print 'What do you want to do?'
print '1 - format names for program 1'
print '2 - format names for program 2'

first_act = raw_input('Enter choice: ')

print names
print first_act

现在，当我运行这个并输入虚拟名称时，我将其放入google doc电子表格进行测试，只要我按下shift + ctl + v，而不按Enter键，我就得到：

seth@linux-1337:~> python pythonproj/names.py
Shoot me some names partner: abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnopWhat do you want to do?
1 - format names for program 1
2 - format names for program 2
Enter choice: abcd,efg,hijkl,mnop
abcd,efg,hijkl,mnop
seth@linux-1337:~> abcd,efg,hijkl,mnop
If 'abcd,efg,hijkl,mnop' is not a typo you can use command-not-found to lookup the package that contains it, like this:
cnf abcd,efg,hijkl,mnop
seth@linux-1337:~> abcd,efg,hijkl,mnop

我是python的新手，到目前为止我不是最有经验的程序员。这是python 2.7。

Answer 1

因为raw_input只需要输入一行，你需要创建一个循环：

names = []
print('Shoot me some names partner: ')
while True:
    try:
        name = raw_input()
    except KeyboardInterrupt:
        break
    names.append(name)

print('What do you want to do?')
print('1 - format names for program 1')
print('2 - format names for program 2')

first_act = raw_input('Enter choice: ')

print(names)
print(first_act)

试运行：

Shoot me some names partner: 
name1
name2
^CWhat do you want to do?
1 - format names for program 1
2 - format names for program 2
Enter choice: 1
['name1', 'name2']
1

注意我在这里使用了^C（Ctrl-C）来表示输入结束。

Answer 2

我不确定你要问的是什么，但是当你使用raw_input（）时，它会删除一个尾随的换行符。

而且医生也这么说。

如果存在prompt参数，则将其写入标准输出没有尾随换行符。然后该函数从输入中读取一行，将其转换为字符串（剥离尾随换行符），然后返回那。读取EOF时，会引发EOFError。

Python raw_input忽略换行符
