Question

我的文本文件中有一行，如下面一行：

hi   everyone  this is good
the weather is good     yes

我想将每个字符串写成一行，如下所示：

  hi
  everyone
  this

我该怎么办？我不知道每个字符串之间的空格数。

谢谢

我使用了这种方法，但它不起作用

text_file = open("1.txt","r")
for line in text_file :
    lline = list(line)
    lline.replace(" ", "")
    line1 = lline.join()
    file.write(line1)

Answer 1

您可以按空格分割线条并展平列表：

lines = ['hi there', 'how    are you   today']
tokens = [token for line in lines for token in line.split()]
# tokens: ['hi', 'there', 'how', 'are', 'you', 'today']

从文件中读取时，代码应为：

with open('1.txt', 'rt') as text_file:
    tokens = [token for line in text_file for token in line.split()]
    target_file.write('\n'.join(tokens))

修改，感谢officialaimm的评论，示例已从re.split(r'\s+', line)简化为line.split()。

Answer 2

您可以使用拆分功能。
像：

 text_file = open("1.txt","r").read()
 for i in text_file.strip().split('\n'):
    [print(j) for j in i.split()]
----
hi
everyone
this
is
good
the
weather
is
good
yes

它会打印结果。

Answer 3

使用re.sub：

In [227]: import re

In [228]: line = '''hi   everyone  this is good
     ...:   the weather is good     yes'''

In [233]: print(re.sub('\s+', '\n', line, re.M | re.DOTALL))
hi
everyone
this
is
good
the
weather
is
good
yes

Answer 4

试试这个，只需确保文件是打开的文件连接即可。

text_file = open("1.txt","r")
for line in text_file :
    lline = line.split()
    line1 = '\n'.join(lline)
    file.write(line1)

将字符串逐字分隔到Python
