Python合并无空白换行的行

Posted 2021-03-19

我需要您解决以下问题。我有一些大的文本文件，例如：

This is the Name of the Person

This is his surname

He likes to sing 
every time.

我只想将He likes to sing行与every time.合并，因为在此之后我要对每个字符串进行其他正则表达式处理。

因此输出应为：

This is the Name of the Person

This is his surname

He likes to sing every time.

我很喜欢用：

for file in file_list:
    with open(file, 'r', encoding='UTF-8', errors='ignore') as f_in:
        for line in f_in:
              if not line.startswith('
'):
                line.replace('
', '')
                print(line)

感谢您的帮助。

答案

您可以分割 上的部分，然后通过分割 来合并每个部分：

with open("data.txt") as f:
    for line in f.read().split("

"):
        print("".join(line.split("
")) + "
")

输出：

This is the Name of the Person

This is his surname

He likes to sing every time.

另一答案

您可以尝试以下方法：

for file in file_list:
    with open(file, 'r', encoding='UTF-8', errors='ignore') as f_in:
        lines = [i.replace('
', '') for i in f_in.read().split('

')]

    # here you do something with your `lines`
