python实现将结构体中多行代码合并为一行

with open('test1.txt','r') as rf:
    content = ''
    lines = rf.readlines()
    
line_index = 0
with open('test2.txt','w') as wf:
    for line in lines:
        content += line.strip()
        line_index+=1
        if line_index>7:
            content += '\n'
            line_index = 0
    wf.write(content)
