【Python】一键提取inp文件结构的脚本

inp=input("输入文件路径:")
# print(type(inp))
ex_txt=inp+'-Struct.inp'
inp=inp+'.inp'

import re
f2= open(ex_txt, 'w')
with open(inp, 'r',encoding="utf-8") as f1:
    row_num=0    
    for i in f1:
        if i.startswith('*'):
            f2.write(i)
        row_num=row_num+1  #进入下一行
f2.close()

print('输出文件--'+ex_txt)

Example
