import re

filename = 'set1.txt'

# 自增数字

i = 0

# 准备空字符串，存新数据

file_data = ""

# 找到数字 替换

with open(filename, "r", encoding="utf-8") as f:

for line in f:

old_str = line.split()[3].strip(',')

print(old_str)

# 用正则查找

# old_str = re.findall(r'\+ \d*', line)[0].replace("+", "").strip()

if old_str in line:

line = line.replace(old_str, str(i))

i += 1

file_data += line

# 写入

with open(filename, "w", encoding="utf-8") as f:

f.write(file_data)

对文件内容按数字进行排序

print(''.join(sorted(open('set1.txt'), key=lambda s: int(s.split()[3].strip(',')))))
