文件合并、去重:
可以使用Python语言中的set数据结构进行去重,然后将去重后的内容写入新的文件中,最后将需要合并的文件逐一读取,将内容写入新文件中即可。
示例代码:
```python
# 文件去重
def file_deduplication(file_path):
with open(file_path, 'r') as f:
lines = f.readlines()
dedup_lines = set(lines)
with open(file_path, 'w') as f:
for line in dedup_lines:
f.write(line)
# 文件合并
def file_merge(file_list, merge_file):
with open(merge_file, 'w') as f:
for file_path in file_list:
with open(file_path, 'r') as f1:
lines = f1.readlines()
for line in lines:
f.write(line)
```
文件排序:
可以使用Python语言中的sorted函数对文件内容进行排序,然后将排序后的内容写入新的文件中。
示例代码:
```python
# 文件排序
def file_sort(file_path):
with open(file_path, 'r') as f:
lines = f.readlines()
sorted_lines = sorted(lines)
with open(file_path, 'w') as f:
for line in sorted_lines:
f.write(line)
```
以上代码仅供参考,实际使用时需要根据具体需求进行修改。
