    在原有的文件上,修改替换,并放到新的文件里
    
    old = open('day','r')
    new = open('new_day','w')
    old_replace = input('please replace content:')
    new_replace = input('please new replace content:')
    
    for i in old:
        if old_replace in i:
            i = i.replace(old_replace,new_replace)
        new.write(i)
    
    old.close()
    new.close()
