python之文件切割保存

Posted 2020-07-26 知_行

最近在看小甲鱼的视频，把写的文件切割代码拿出来捋捋

#-*- coding:utf-8 -*-
f = open(‘foo.txt‘)

man = [] #定义两个空列表
women =[]
count = 1 #初始化计数器

for each_line in f:
    if each_line[:6] != ‘======‘: #如果文档未遇到分隔符，则切割
        (role,line_spoken) = each_line.split(‘:‘,1)#遇到冒号则切割1次
        if role == ‘boy‘:
            man.append(line_spoken) #将角色boy的话添加到man列表
        if role == ‘girl‘:
            women.append(line_spoken)
    else:
        file_name_boy = ‘boy_‘+ str(count) + ‘.txt‘       #定义文件名
        file_name_girl = ‘girl_‘ + str(count) + ‘.txt‘
        
        boy_file = open(file_name_boy,‘w‘)#创建文件
        girl_file = open(file_name_girl,‘w‘)
        
        boy_file.writelines(man)#将列表内容分别写入文件
        girl_file.writelines(women)
        
        boy_file.close()
        girl_file.close()
        
        man = []
        women = []
        count += 1
        
file_name_boy = ‘boy_‘+ str(count) + ‘.txt‘
file_name_girl = ‘girl_‘ + str(count) + ‘.txt‘
        
boy_file = open(file_name_boy,‘w‘)
girl_file = open(file_name_girl,‘w‘)
        
boy_file.writelines(man)
girl_file.writelines(women)
        
boy_file.close()
girl_file.close()

f.close()
        

升级版代码捋捋

#-*- coding:utf-8 -*-

#自定义保存文件函数
def save_file(man, women, count):
    file_name_boy = ‘boy_‘+ str(count) + ‘.txt‘ 
    file_name_girl = ‘girl_‘ + str(count) + ‘.txt‘
        
    boy_file = open(file_name_boy,‘w‘)
    girl_file = open(file_name_girl,‘w‘)
        
    boy_file.writelines(man)
    girl_file.writelines(women)
        
    boy_file.close()
    girl_file.close()
        
 #自定义分割文件函数
def fenge(filename):    
    f = open(filename)
    
    man = []
    women =[]
    count = 1

    for each_line in f:
        if each_line[:6] != ‘======‘:
            (role,line_spoken) = each_line.split(‘:‘, 1)
            if role == ‘boy‘:
                man.append(line_spoken)
            if role == ‘girl‘:
                women.append(line_spoken)
        else:
            save_file(man, women, count)
                    
            man = []
            women = []
            count += 1
            
    save_file(man, women, count)

    f.close()
    
fenge(‘foo.txt‘)      

 

END!
