# 引言

因为工作需要，引入自动化脚本，原先手工生成的文本数据，现在通过代码生成，为了保证代码生成的和手工生成的一致性，故写此脚本。

⚠ 文本顺序不影响最终结果，如果要完全一致，则直接考虑md5即可。

# 步骤

1. 读入文件
2. 分割换行
3. 去除空行
4. 排序
5. 生成新文件
6. 计算md5
7. 输出结果

# 技术

1. sort
2. hashlib

# 代码

```python
import hashlib

print("[i] Read text file and output sorted file")
print("[!] Warning new file will del(ignored) blank lines")
file = "%"
files_list = []
while True:

file = input("[#] File:> ")
    if file == "": break
    files_list.append(file)
    result = ""
    with open(file, 'r') as f:
        text = f.read()
        lines = text.split("\n")
        for i in range(len(lines)):
            if lines[i] == "":
                del lines[i]
    lines.sort()
    with open(file + "new", 'w') as f:
        f.write("\n".join(lines))

md5 = []
name_max_len = 0
for new_file in files_list:
    name_max_len = max(name_max_len, len(new_file))
    file_name = new_file + "new"
    with open(file_name, 'r') as f:
        text = f.read()
        md5.append(hashlib.md5(bytes(text, encoding='utf-8')).hexdigest())

print("[i] " + "-" * (name_max_len + 35))
fm = "[i] " + "|{:^32s}|{:^" + str(name_max_len) + "}|"
print(fm.format("md5", "file"))
print("[i] " + "-" * (name_max_len + 35))
fm = "[i] " + "|{:^32s}|{:<" + str(name_max_len) + "}|"
for i in range(len(md5)):
    print(fm.format(md5[i], files_list[i]))
print("[i] " + "-" * (name_max_len + 35))
print("[i] " + "Result: " + "√ Exactly consistent" if len(set(md5)) == 1 else "× Not exactly consistent")
```
