结论：有主角出场的章节数量，约占总章节数的46%
思路：用python统计有“徐峻”出现的章节数量，除以总章节数量
代码：name = '复活之战斗在第三帝国'
in_file_name = name + '.txt'

input = open(in_file_name,encoding='utf-8')

lines = input.readlines()

new_zhang = False
zhang = 0
youzhang = 0
for line in lines:

    if line[0]=="第" and line.find("章")!=-1:
        new_zhang = True
        zhang = zhang+1
        continue
    if new_zhang:
        if line.find("徐峻")!=-1:
            new_zhang = False
            youzhang = youzhang+1
            continue
   
print(youzhang/zhang)
