txt文件里的文本内容根据指定的分割字符数目区间进行随机换行切分,分割后的结果覆盖原文件python类实现

以下是一个实现随机换行切分的 Python 类的示例:
```python
import random
import os
class FileSplitter:
def __init__(self, file_path, min_chars_per_line, max_chars_per_line):
self.file_path = file_path
self.min_chars_per_line = min_chars_per_line
self.max_chars_per_line = max_chars_per_line
def split(self):
# 读取文件内容
f = open(self.file_path, 'r')
text = f.read()
f.close()
# 随机换行切分文本内容
new_text = ""
curr_pos = 0
while curr_pos < len(text):
# 随机确定下一行的长度
line_length = random.randint(self.min_chars_per_line, self.max_chars_per_line)
# 确定下一行的结束位置
end_pos = min(curr_pos + line_length, len(text))
while end_pos < len(text) and text[end_pos] != " ":
end_pos += 1
if end_pos >= len(text):
new_text += text[curr_pos:]
break
# 添加下一行到新文本中
new_text += text[curr_pos:end_pos+1] + "\n"
curr_pos = end_pos + 1
# 将新文本写回原文件
f = open(self.file_path, 'w')
f.write(new_text)
f.close()
print("File split complete.")
# 测试类
file_path = "test.txt"
min_chars_per_line = 20
max_chars_per_line = 30
if os.path.exists(file_path):
splitter = FileSplitter(file_path, min_chars_per_line, max_chars_per_line)
splitter.split()
else:
print("File not found.")
```
你可以根据需要修改分割字符数目区间等参数,然后创建一个 `FileSplitter` 对象并调用 `split()` 方法进行文本分割。请注意该类将直接修改原文件,因此在调用之前请确保备份重要数据。
