Python读取文件首行和最后一行
-
注意事项
文件打开方式为rb
file = open('XXX','rb')
- 使用链接中第2种批量处理文件的最后一行
count = 0
for i in range(88,100):
for j in range(0,30):
if os.access('solution//charac_'+str(i)+'_'+str(j)+'.txt', os.F_OK): # 如果文件存在,则进行下一步操作
file = open('solution//charac_'+str(i)+'_'+str(j)+'.txt','rb') # 文件打开方式为'rb',否则seek函数会报错
offset = -50
while True:
file.seek(offset, 2)
lines = file.readlines()
if len(lines) >= 2:
last_line = lines[-1]
break
offset *= 2
res = int(last_line[8:10])
if res <= 79:
count=count+1
print(count)
