按特定排列合并每个文本文件的最后 3 行

  • 772

我的目录中有大量 txt 文件E:\Desktop\Social_media\edit8\New folder，每个文件的排列类似于以下内容：

Bolt
2,739,393
Classmates
1,267,092
SixDegrees
1,077,353
PlanetAll
552,488
theGlobe
437,847
OpenDiary
9,251
1998
MARCH
034+

现在我想合并每个 txt 文件的最后 3 行，如下所示：

Bolt
2,739,393
Classmates
1,267,092
SixDegrees
1,077,353
PlanetAll
552,488
theGlobe
437,847
OpenDiary
9,251
034+ MARCH 1998

这意味着最后 3 行必须有这样的排列number+ month year

我为此编写了以下 python 脚本，但我不知道为什么不起作用：

import os

# Define the directory where your text files are located
directory_path = r'E:\Desktop\Social_media\edit8\New folder'

# Function to rearrange the lines and write to a new file
def rearrange_lines(file_path):
    with open(file_path, 'r') as file:
        lines = [line.strip() for line in file.readlines() if line.strip()]  # Read non-empty lines

    # Check if there are at least 3 non-empty lines
    if len(lines) >= 3:
        lines[-1], lines[-2], lines[-3] = lines[-3], lines[-2], lines[-1]  # Rearrange the last 3 lines

        # Create a new file with the rearranged lines
        with open(file_path, 'w') as file:
            file.write('\n'.join(lines))

# Iterate through each file in the directory
for root, dirs, files in os.walk(directory_path):
    for file_name in files:
        if file_name.endswith('.txt'):
            file_path = os.path.join(root, file_name)
            rearrange_lines(file_path)
            print(f'Rearranged lines in {file_name}')

print('Done!')

我的脚本问题出在哪里？以及如何解决这个问题？

    您没有将结果中的最后 3 行合并为一行。

    # Function to rearrange the lines and write to a new file
def rearrange_lines(file_path):
    with open(file_path, 'r') as file:
        lines = [line.strip() for line in file.readlines() if line.strip()]  # Read non-empty lines

    # Check if there are at least 3 non-empty lines
    if len(lines) >= 3:
        # reverse last 3 lines, join them with space, and replace with this result
        lines[-3:] = [' '.join(lines[-1:-4:-1])]

        # Create a new file with the rearranged lines
        with open(file_path, 'w') as file:
            file.write('\n'.join(lines))

    分配给lines[-3:]是切片替换。我们用单行列表替换它。

  2. 我在评论的帮助下发现了我的脚本的问题：

    import os

# Define the directory where your text files are located
directory_path = r'E:\Desktop\Social_media\edit8\New folder'

# Function to rearrange and combine the lines and write to a new file
def rearrange_lines(file_path):
    with open(file_path, 'r') as file:
        lines = [line.strip() for line in file.readlines() if line.strip()]  # Read non-empty lines

    # Check if there are at least 3 non-empty lines
    if len(lines) >= 3:
        combined_line = f'{lines[-1]} {lines[-2]} {lines[-3]}'  # Combine the last 3 lines
        lines = lines[:-3]  # Remove the last 3 lines
        lines.append(combined_line)  # Append the combined line

        # Create a new file with the rearranged lines
        with open(file_path, 'w') as file:
            file.write('\n'.join(lines))

# Iterate through each file in the directory
for root, dirs, files in os.walk(directory_path):
    for file_name in files:
        if file_name.endswith('.txt'):
            file_path = os.path.join(root, file_name)
            rearrange_lines(file_path)
            print(f'Rearranged lines in {file_name}')

print('Done!')
